-
-## ⚠️ MANDATORY: GitHub agent disclosure
-
-**Always required. No exceptions.**
-
-Whenever you perform **any** GitHub action on behalf of the user, you **must** disclose that an AI agent (Cursor) wrote the content and is acting on the user's behalf — **not the user personally**. Do this **before** submitting; never post first and add the disclosure later.
-
-Applies to **all** GitHub interactions, including:
-
-- Pull requests (titles, descriptions, and reviews)
-- PR comments and inline review comments
-- Issues (new issues, comments, and updates)
-- Any other post or reply on GitHub
-
-**How to disclose:** Put it prominently at the **top** of every PR description, review body, comment, or issue. Use wording like:
-
-
-Inline review comments must include a short disclosure too (e.g. `> Generated by Cursor acting on the user's behalf, not the user personally.`).
-
-**Never** submit a GitHub action without this disclosure.
-
----
-
-Always run the spellcheck before raising a PR:
-
-```bash
-bash scripts/spelling.sh
-```
-
-This is also included in the full CI pipeline via `make local test`.
-
-## Cursor Cloud specific instructions
-
-### Overview
-
-**yq** is a Go CLI for querying and transforming YAML, JSON, XML, INI, and other structured formats. There are no long-running services — development is build-and-test against a local `./yq` binary.
-
-### Prerequisites
-
-- **Go ≥ 1.25** (see `go.mod`)
-- **Bash** (acceptance tests)
-- **Docker/Podman** is optional; use `make local <target>` to run natively when containers are unavailable
-
-### PATH
-
-After `scripts/devtools.sh`, add Go tool binaries to PATH:
-
-```bash
-export PATH="$HOME/go/bin:$PATH"
-```
-
-`golangci-lint` and `typos` install to `$HOME/go/bin`; `gosec` installs to `./bin/gosec` in the repo root.
-
-### Common commands (local, no Docker)
-
-| Task | Command |
-|------|---------|
-| Install dev tools | `bash scripts/devtools.sh` |
-| Vendor dependencies | `make local vendor` |
-| Build binary | `go build -o yq .` or `make local build` |
-| Format | `make local format` |
-| Lint | `make local check` |
-| Unit tests | `make local test` or `bash scripts/test.sh` |
-| Acceptance (E2E) | `bash scripts/acceptance.sh` (requires `./yq` built first) |
-
-`make local build` runs the full CI chain (format → spelling → gosec → lint → unit tests → build → acceptance). For a faster loop, build with `go build -o yq .` and run `bash scripts/acceptance.sh`.
-
-### Caveats
-
-- **`make` without `local`** tries Docker/Podman (`Dockerfile.dev`). In Cloud Agent VMs without Docker, always prefix with `make local`.
-- **Spelling step** uses `typos` (installed by `scripts/devtools.sh`).
-- **`make local test` / `scripts/check.sh`** require `golangci-lint` on PATH (`devtools.sh`).
-
----
-
-# General rules
-✅ **DO:**
-- You can use ./yq with the `--debug-node-info` flag to get a deeper understanding of the ast.
-- run ./scripts/format.sh to format the code; then ./scripts/check.sh lint and finally ./scripts/spelling.sh to check spelling.
-- Add comprehensive tests to cover the changes
-- Run test suite to ensure there is no regression
-- Use UK english spelling
-- **Follow the mandatory GitHub agent disclosure rule above** on every GitHub action — no exceptions
-
-❌ **DON'T:**
-- Git add or commit
-- Add comments to functions that are self-explanatory
-- **Post to GitHub without the mandatory agent disclosure** (PRs, reviews, comments, issues, or any other GitHub interaction)

-# Adding a New Encoder/Decoder
-
-This guide explains how to add support for a new format (encoder/decoder) to yq without modifying `candidate_node.go`.
-
-## Overview
-
-The encoder/decoder architecture in yq is based on two main interfaces:
-
-- **Encoder**: Converts a `CandidateNode` to output in a specific format
-- **Decoder**: Reads input in a specific format and creates a `CandidateNode`
-
-Each format is registered in `pkg/yqlib/format.go` and made available through factory functions.
-
-## Architecture
-
-### Key Files
-
-- `pkg/yqlib/encoder.go` - Defines the `Encoder` interface
-- `pkg/yqlib/decoder.go` - Defines the `Decoder` interface
-- `pkg/yqlib/format.go` - Format registry and factory functions
-- `pkg/yqlib/operator_encoder_decoder.go` - Encode/decode operators
-- `pkg/yqlib/encoder_*.go` - Encoder implementations
-- `pkg/yqlib/decoder_*.go` - Decoder implementations
-
-### Interfaces
-
-**Encoder Interface:**
-```go
-type Encoder interface {
-    Encode(writer io.Writer, node *CandidateNode) error
-    PrintDocumentSeparator(writer io.Writer) error
-    PrintLeadingContent(writer io.Writer, content string) error
-    CanHandleAliases() bool
-}
-```
-
-**Decoder Interface:**
-```go
-type Decoder interface {
-    Init(reader io.Reader) error
-    Decode() (*CandidateNode, error)
-}
-```
-
-## Step-by-Step: Adding a New Encoder/Decoder
-
-### Step 1: Create the Encoder File
-
-Create `pkg/yqlib/encoder_<format>.go` implementing the `Encoder` interface:
-- `Encode()` - Convert a `CandidateNode` to your format and write to the output writer
-- `PrintDocumentSeparator()` - Handle document separators if your format requires them
-- `PrintLeadingContent()` - Handle leading content/comments if supported
-- `CanHandleAliases()` - Return whether your format supports YAML aliases
-
-See `encoder_json.go` or `encoder_base64.go` for examples.
-
-### Step 2: Create the Decoder File
-
-Create `pkg/yqlib/decoder_<format>.go` implementing the `Decoder` interface:
-- `Init()` - Initialize the decoder with the input reader and set up any needed state
-- `Decode()` - Decode one document from the input and return a `CandidateNode`, or `io.EOF` when finished
-
-See `decoder_json.go` or `decoder_base64.go` for examples.
-
-### Step 3: Create Tests (Mandatory)
-
-Create a test file `pkg/yqlib/<format>_test.go` using the `formatScenario` pattern:
-- Define test scenarios as `formatScenario` structs with fields: `description`, `input`, `expected`, `scenarioType`
-- `scenarioType` can be `"decode"` (test decoding to YAML) or `"roundtrip"` (encode/decode preservation)
-- Create a helper function `test<Format>Scenario()` that switches on `scenarioType`
-- Create main test function `Test<Format>FormatScenarios()` that iterates over scenarios
-- The main test function should use `documentScenarios` to ensure testcase documentation is generated.
-
-Test coverage must include:
-- Basic data types (scalars, arrays, objects/maps)
-- Nested structures
-- Edge cases (empty inputs, special characters, escape sequences)
-- Format-specific features or syntax
-- Round-trip tests: decode → encode → decode should preserve data
-
-See `hcl_test.go` for a complete example.
-
-### Step 4: Register the Format in format.go
-
-Edit `pkg/yqlib/format.go`:
-
-1. Add a new format variable:
-   - `"<format>"` is the formal name (e.g., "json", "yaml")
-   - `[]string{...}` contains short aliases (can be empty)
-   - The first function creates an encoder (can be nil for encode-only formats)
-   - The second function creates a decoder (can be nil for decode-only formats)
-
-2. Add the format to the `Formats` slice in the same file
-
-See existing formats in `format.go` for the exact structure.
-
-### Step 5: Handle Encoder Configuration (if needed)
-
-If your format has preferences/configuration options:
-
-1. Create a preferences struct with your configuration fields
-2. Update the encoder to accept preferences in its factory function
-3. Update `format.go` to pass the configured preferences
-4. Update `operator_encoder_decoder.go` if special indent handling is needed (see existing formats like JSON and YAML for the pattern)
-
-This pattern is optional and only needed if your format has user-configurable options.
-
-## Build Tags
-
-Use build tags to allow optional compilation of formats:
-- Add `//go:build !yq_no<format>` at the top of your encoder and decoder files
-- Create a no-build version in `pkg/yqlib/no_<format>.go` that returns nil for encoder/decoder factories
-
-This allows users to compile yq without certain formats using: `go build -tags yq_no<format>`
-
-## Working with CandidateNode
-
-The `CandidateNode` struct represents a YAML node with:
-- `Kind`: The node type (ScalarNode, SequenceNode, MappingNode)
-- `Tag`: The YAML tag (e.g., "!!str", "!!int", "!!map")
-- `Value`: The scalar value (for ScalarNode only)
-- `Content`: Child nodes (for SequenceNode and MappingNode)
-
-Key methods:
-- `node.guessTagFromCustomType()` - Infer the tag from Go type
-- `node.AsList()` - Convert to a list for processing
-- `node.CreateReplacement()` - Create a new replacement node
-- `NewCandidate()` - Create a new CandidateNode
-
-## Key Points
-
-✅ **DO:**
-- Implement only the `Encoder` and `Decoder` interfaces
-- Register your format in `format.go` only
-- Keep format-specific logic in your encoder/decoder files
-- Use the candidate_node style attribute to store style information for round-trip. Ask if this needs to be updated with new styles.
-- Use build tags for optional compilation
-- Add comprehensive tests
-- Run the specific encoder/decoder test (e.g. <format>_test.go) whenever you make ay changes to the encoder_<format> or decoder_<format>
-- Handle errors gracefully
-- Add the no build directive, like the xml encoder and decoder, that enables a minimal yq builds. e.g.  `//go:build !yq_<format>`. Be sure to also update the build_small-yq.sh and build-tinygo-yq.sh to not include the new format.
-
-❌ **DON'T:**
-- Modify `candidate_node.go` to add format-specific logic
-- Add format-specific fields to `CandidateNode`
-- Create special cases in core navigation or evaluation logic
-- Bypass the encoder/decoder interfaces
-- Use candidate_node tag attribute for anything other than indicate the data type
-
-## Examples
-
-Refer to existing format implementations for patterns:
-
-- **Simple encoder/decoder**: `encoder_json.go`, `decoder_json.go`
-- **Complex with preferences**: `encoder_yaml.go`, `decoder_yaml.go`
-- **Encoder-only**: `encoder_sh.go` (ShFormat has nil decoder)
-- **String-only operations**: `encoder_base64.go`, `decoder_base64.go`
-
-## Testing Your Implementation (Mandatory)
-
-Tests must be implemented in `<format>_test.go` following the `formatScenario` pattern:
-
-1. **Create test scenarios** using the `formatScenario` struct with fields:
-   - `description`: Brief description of what's being tested
-   - `input`: Sample input in your format
-   - `expected`: Expected output (typically in YAML for decode tests)
-   - `scenarioType`: Either `"decode"` or `"roundtrip"`
-
-2. **Test coverage must include:**
-   - Basic data types (scalars, arrays, objects/maps)
-   - Nested structures
-   - Edge cases (empty inputs, special characters, escape sequences)
-   - Format-specific features or syntax
-   - Round-trip tests: decode → encode → decode should preserve data
-
-3. **Test function pattern:**
-   - `test<Format>Scenario()`: Helper function that switches on `scenarioType`
-   - `Test<Format>FormatScenarios()`: Main test function that iterates over scenarios
-
-4. **Example from existing formats:**
-   - See `hcl_test.go` for a complete example
-   - See `yaml_test.go` for YAML-specific patterns
-   - See `json_test.go` for more complex scenarios
-
-## Common Patterns
-
-### Format with Indentation
-Use preferences to control output formatting:
-```go
-type <format>Preferences struct {
-    Indent int
-}
-
-func (prefs *<format>Preferences) Copy() <format>Preferences {
-    return *prefs
-}
-```
-
-### Multiple Documents
-Decoders should support reading multiple documents:
-```go
-func (dec *<format>Decoder) Decode() (*CandidateNode, error) {
-    if dec.finished {
-        return nil, io.EOF
-    }
-    // ... decode next document ...
-    if noMoreDocuments {
-        dec.finished = true
-    }
-    return candidate, nil
-}
-```

-# Adding a New Operator
-
-This guide explains how to add a new operator to yq. Operators are the core of yq's expression language and process `CandidateNode` objects without requiring modifications to `candidate_node.go` itself.
-
-## Overview
-
-Operators transform data by implementing a handler function that processes a `Context` containing `CandidateNode` objects. Each operator is:
-
-1. Defined as an `operationType` in `operation.go`
-2. Registered in the lexer in `lexer_participle.go`
-3. Implemented in its own `operator_<type>.go` file
-4. Tested in `operator_<type>_test.go`
-5. Documented in `pkg/yqlib/doc/operators/headers/<type>.md`
-
-## Architecture
-
-### Key Files

-### Core Types
-
-**operationType:**
-```go
-type operationType struct {
-    Type                 string          // Unique operator name (e.g., "REVERSE")
-    NumArgs              uint            // Number of arguments (0 for no args)
-    Precedence           uint            // Operator precedence (higher = higher precedence)
-    Handler              operatorHandler // The function that executes the operator
-    CheckForPostTraverse bool            // Whether to apply post-traversal logic
-    ToString             func(*Operation) string // Custom string representation
-}
-```
-
-**operatorHandler signature:**
-```go
-type operatorHandler func(*dataTreeNavigator, Context, *ExpressionNode) (Context, error)
-```
-
-**expressionScenario for tests:**
-```go
-type expressionScenario struct {
-    description      string
-    subdescription   string
-    document         string
-    expression       string
-    expected         []string
-    skipDoc          bool
-    expectedError    string
-}
-```
-
-## Step-by-Step: Adding a New Operator
-
-### Step 1: Create the Operator Implementation File
-
-Create `pkg/yqlib/operator_<type>.go` implementing the operator handler function:
-- Implement the `operatorHandler` function signature
-- Process nodes from `context.MatchingNodes`
-- Return a new `Context` with results using `context.ChildContext()`
-- Use `candidate.CreateReplacement()` or `candidate.CreateReplacementWithComments()` to create new nodes
-- Handle errors gracefully with meaningful error messages
-
-See `operator_reverse.go` or `operator_keys.go` for examples.
-
-### Step 2: Register the Operator in operation.go
-
-Add the operator type definition to `pkg/yqlib/operation.go`:
-
-```go
-var <type>OpType = &operationType{
-    Type:       "<TYPE>",          // All caps, matches pattern in lexer
-    NumArgs:    0,                 // 0 for no args, 1+ for args
-    Precedence: 50,                // Typical range: 40-55
-    Handler:    <type>Operator,    // Reference to handler function
-}
-```
-
-**Precedence guidelines:**
-- 10-20: Logical operators (OR, AND, UNION)
-- 30: Pipe operator
-- 40: Assignment and comparison operators
-- 42: Arithmetic operators (ADD, SUBTRACT, MULTIPLY, DIVIDE)
-- 50-52: Most other operators
-- 55: High precedence (e.g., GET_VARIABLE)
-
-**Optional fields:**
-- `CheckForPostTraverse: true` - If your operator can have another directly after it without the pipe character. Most of the time this is false.
-- `ToString: customToString` - Custom string representation (rarely needed)
-
-### Step 3: Register the Operator in lexer_participle.go
-
-Edit `pkg/yqlib/lexer_participle.go` to add the operator to the lexer rules:
-- Use `simpleOp()` for simple keyword patterns
-- Use object syntax for regex patterns or complex syntax
-- Support optional characters with `_?` and aliases with `|`
-
-See existing operators in `lexer_participle.go` for pattern examples.
-
-### Step 4: Create Tests (Mandatory)
-
-Create `pkg/yqlib/operator_<type>_test.go` using the `expressionScenario` pattern:
-- Define test scenarios with `description`, `document`, `expression`, and `expected` fields
-- `expected` is a slice of strings showing output format: `"D<doc>, P[<path>], (<tag>)::<value>\n"`
-- Set `skipDoc: true` for edge cases you don't want in generated documentation
-- Include `subdescription` for longer test names
-- Set `expectedError` if testing error cases
-- Create main test function that iterates over scenarios
-- The main test function should use `documentScenarios` to ensure testcase documentation is generated.
-
-Test coverage must include:
-- Basic data types and nested structures
-- Edge cases (empty inputs, special characters, type errors)
-- Multiple outputs if applicable
-- Format-specific features
-
-See `operator_reverse_test.go` for a simple example and `operator_keys_test.go` for complex cases.
-
-### Step 5: Create Documentation Header
-
-Create `pkg/yqlib/doc/operators/headers/<type>.md`:
-- Use the exact operator name as the title
-- Include a concise 1-2 sentence summary
-- Add additional context or examples if the operator is complex
-
-See existing headers in `doc/operators/headers/` for examples.
-
-## Working with Context and CandidateNode
-
-### Context Management
-- `context.ChildContext(results)` - Create child context with results
-- `context.GetVariable("varName")` - Get variables stored in context
-- `context.SetVariable("varName", value)` - Set variables in context
-
-### CandidateNode Operations
-- `candidate.CreateReplacement(ScalarNode, "!!str", stringValue)` - Create a replacement node
-- `candidate.CreateReplacementWithComments(SequenceNode, "!!seq", candidate.Style)` - With style preserved
-- `candidate.Kind` - The node type (ScalarNode, SequenceNode, MappingNode)
-- `candidate.Tag` - The YAML tag (!!str, !!int, etc.)
-- `candidate.Value` - The scalar value (for ScalarNode only)
-- `candidate.Content` - Child nodes (for SequenceNode and MappingNode)
-- `candidate.guessTagFromCustomType()` - Infer the tag from Go type
-- `candidate.AsList()` - Convert to a list representation
-
-## Key Points
-
-✅ **DO:**
-- Implement the operator handler with the correct signature
-- Register in `operation.go` with appropriate precedence
-- Add the lexer pattern in `lexer_participle.go`
-- Write comprehensive tests covering normal and edge cases
-- Create a documentation header in `doc/operators/headers/`
-- Use `Context.ChildContext()` for proper context threading
-- Handle all node types gracefully
-- Return meaningful error messages
-
-❌ **DON'T:**
-- Modify `candidate_node.go` (operators shouldn't need this)
-- Modify core navigation or evaluation logic
-- Bypass the handler function pattern
-- Add format-specific or operator-specific fields to `CandidateNode`
-- Skip tests or documentation
-
-## Examples
-
-Refer to existing operator implementations for patterns:
-
-- **No-argument operator**: `operator_reverse.go` - Processes arrays/sequences
-- **Single-argument operator**: `operator_map.go` - Takes an expression argument
-- **Complex multi-output**: `operator_keys.go` - Produces multiple results
-- **With preferences**: `operator_to_number.go` - Configuration options
-- **Error handling**: `operator_error.go` - Control flow with errors
-- **String operations**: `operator_strings.go` - Multiple related operators
-
-## Testing Patterns
-
-Refer to existing test files for specific patterns:
-- Basic expression tests in `operator_reverse_test.go`
-- Multi-output tests in `operator_keys_test.go`
-- Error handling tests in `operator_error_test.go`
-- Tests with `skipDoc` flag to exclude from generated documentation
-
-## Common Patterns
-
-Refer to existing operator implementations for these patterns:
-- Simple transformation: see `operator_reverse.go`
-- Type checking: see `operator_error.go`
-- Working with arguments: see `operator_map.go`
-- Post-traversal operators: see `operator_with.go`

-Not all new PRs will be merged in 
-
-It's recommended to check with the owner first (e.g. raise an issue) to discuss a new feature before developing, to ensure your hard efforts don't go to waste.
-
-PRs to fix bugs and issues are almost always welcome :pray: please ensure you write tests as well.
-
-The following types of PRs will _not_ be accepted:
-- **Significant refactors** take a lot of time to understand and can have all sorts of unintended side effects. If you think there's a better way to do things (that requires significant changes) raise an issue for discussion first :)
-- **Release pipeline PRs** are a security risk - it's too easy for a serious vulnerability to sneak in (either intended or not). If there is a new cool way of releasing things, raise an issue for discussion first - it will need to be gone over with a fine tooth comb.
-- **Version bumps** are handled by dependabot, the bot will auto-raise PRs and they will be regularly merged in. 
-- **New release platforms** At this stage, yq is not going to maintain any other release platforms other than GitHub and Docker - that said, I'm more than happy to put in other community maintained methods in the README for visibility :heart:

 # Development
 
-## Initial Setup
+1. Install (Golang)[https://golang.org/]
+1. Run  `scripts/devtools.sh` to install the required devtools
+2. Run `make [local] vendor` to install the vendor dependencies
+2. Run `make [local] test` to ensure you can run the existing tests
+3. Write unit tests - (see existing examples). Changes will not be accepted without corresponding unit tests.
+4. Make the code changes.
+5. `make [local] test` to lint code and run tests
+6. Profit! ok no profit, but raise a PR and get kudos :)
 
-1. Install [Golang](https://golang.org/) (version 1.24.0 or later)
-2. Run `scripts/devtools.sh` to install required development tools:
-   - golangci-lint for code linting
-   - gosec for security analysis
-3. Run `make [local] vendor` to install vendor dependencies
-4. Run `make [local] test` to ensure you can run the existing tests
-
-## Development Workflow
-
-1. **Write unit tests first** - Changes will not be accepted without corresponding unit tests (see Testing section below)
-2. **Make your code changes**
-3. **Run tests and linting**: `make [local] test` (this runs formatting, linting, security checks, and tests)
-4. **Create your PR** and get kudos! :)
-
-## Make Commands
-
-- Use `make [local] <command>` for local development (runs in Docker container)
-- Use `make <command>` for CI/CD environments
-- Common commands:
-  - `make [local] vendor` - Install dependencies
-  - `make [local] test` - Run all checks and tests
-  - `make [local] build` - Build the yq binary
-  - `make [local] format` - Format code
-  - `make [local] check` - Run linting and security checks
-
-# Code Quality
-
-## Linting and Formatting
-
-The project uses strict linting rules defined in `.golangci.yml`. All code must pass:
-
-- **Code formatting**: gofmt, goimports, gci
-- **Linting**: revive, errorlint, gosec, misspell, and others
-- **Security checks**: gosec security analysis
-- **Spelling checks**: misspell detection
-
-Run `make [local] check` to verify your code meets all quality standards.
-
-## Code Style Guidelines
-
-- Follow standard Go conventions
-- Use meaningful variable names
-- Add comments for public functions and complex logic
-- Keep functions focused and reasonably sized
-- Use the project's existing patterns and conventions
-
-# Testing
-
-## Test Structure
-
-Tests in yq use the `expressionScenario` pattern. Each test scenario includes:
-- `expression`: The yq expression to test
-- `document`: Input YAML/JSON (optional)
-- `expected`: Expected output
-- `skipDoc`: Whether to skip documentation generation
-
-## Writing Tests
-
-1. **Find the appropriate test file** (e.g., `operator_add_test.go` for addition operations)
-2. **Add your test scenario** to the `*OperatorScenarios` slice
-3. **Run the specific test**: `go test -run TestAddOperatorScenarios` (replace with appropriate test name)
-4. **Verify documentation generation** (see Documentation section)
-
-## Test Examples
-
-```go
-var addOperatorScenarios = []expressionScenario{
-    {
-        skipDoc:    true,
-        expression: `"foo" + "bar"`,
-        expected: []string{
-            "D0, P[], (!!str)::foobar\n",
-        },
-    },
-    {
-        document:   "apples: 3",
-        expression: `.apples + 3`,
-        expected: []string{
-            "D0, P[apples], (!!int)::6\n",
-        },
-    },
-}
-```
-
-## Running Tests
-
-- **All tests**: `make [local] test`
-- **Specific test**: `go test -run TestName`
-- **With coverage**: `make [local] cover`
 
 # Documentation
 
-## Documentation Generation
+The documentation is a bit of a mixed bag (sorry in advance, I do plan on simplifying it...) - with some parts automatically generated and stiched together and some statically defined.
 
-The project uses a documentation system that combines static headers with dynamically generated content from tests.
+Documentation is written in markdown, and is published in the 'gitbook' branch.
 
-### How It Works
+The various operator documentation (e.g. 'strings') are generated from the 'master' branch, and have a statically defined header (e.g. `pkg/yqlib/doc/operators/headers/add.md`) and the bulk of the docs are generated from the unit tests e.g. `pkg/yqlib/operator_add_test.go`.
 
-1. **Static headers** are defined in `pkg/yqlib/doc/operators/headers/*.md`
-2. **Dynamic content** is generated from test scenarios in `*_test.go` files
-3. **Generated docs** are created in `pkg/yqlib/doc/*.md` by concatenating headers with test-generated content
-4. **Documentation is synced** to the gitbook branch for the website
+The pipeline will run the tests and automatically concatenate the files together, and put them under 
+`pkg/qylib/doc/add.md`. These files are checked in the master branch (and are copied to the gitbook branch as part of the release process).
 
-### Updating Operator Documentation
+## How to contribute
 
-#### For Test-Generated Documentation
+The first step is to find if what you want is automatically generated or not - start by looking in the master branch. 
 
-Most operator documentation is generated from tests. To update:
+### Updating dynamic documentation from master
+- Search for the documentation you want to update. If you find matches in a `*_test.go` file - update that, as that will automatically update the matching `*.md` file 
+- Assuming you are updating a `*_test.go` file, once updated, run the test to regenerated the docs. E.g. for the 'Add' test generated docs, from the pkg/yqlib folder run:
+`go test -run TestAddOperatorScenarios` which will run that test defined in the `operator_add_test.go` file.
+- Ensure the tests still pass, and check the generated documentation have your update.
+- Note: If the documentation is only in a `headers/*.md` file, then just update that directly
+- Raise a PR to merge the changes into master!
 
-1. **Find the test file** (e.g., `operator_add_test.go`)
-2. **Update test scenarios** - each `expressionScenario` with `skipDoc: false` becomes documentation
-3. **Run the test** to regenerate docs:
-   ```bash
-   cd pkg/yqlib
-   go test -run TestAddOperatorScenarios
-   ```
-4. **Verify the generated documentation** in `pkg/yqlib/doc/add.md`
-5. **Create a PR** with your changes
+### Updating static documentation from the gitbook branch
+If you haven't found what you want to update in the master branch, then check the gitbook branch directly as there are a few pages in there that are not in master.
 
-#### For Header-Only Documentation
-
-If documentation exists only in `headers/*.md` files:
-1. **Update the header file directly** (e.g., `pkg/yqlib/doc/operators/headers/add.md`)
-2. **Create a PR** with your changes
-
-### Updating Static Documentation
-
-For documentation not in the master branch:
-
-1. **Check the gitbook branch** for additional pages
-2. **Update the `*.md` files** directly
-3. **Create a PR** to the gitbook branch
-
-### Documentation Best Practices
-
-- **Write clear, concise examples** in test scenarios
-- **Use meaningful variable names** in examples
-- **Include edge cases** and error conditions
-- **Test your documentation changes** by running the specific test
-- **Verify generated output** matches expectations
-
-Note: PRs with small changes (e.g. minor typos) may not be merged (see https://joel.net/how-one-guy-ruined-hacktoberfest2020-drama).

-# Troubleshooting
-
-## Common Setup Issues
-
-### Docker/Podman Issues
-- **Problem**: `make` commands fail with Docker errors
-- **Solution**: Ensure Docker or Podman is running and accessible
-- **Alternative**: Use `make local <command>` to run in containers
-
-### Go Version Issues
-- **Problem**: Build fails with Go version errors
-- **Solution**: Ensure you have Go 1.24.0 or later installed
-- **Check**: Run `go version` to verify
-
-### Vendor Dependencies
-- **Problem**: `make vendor` fails or dependencies are outdated
-- **Solution**: 
-  ```bash
-  go mod tidy
-  make [local] vendor
-  ```
-
-### Linting Failures
-- **Problem**: `make check` fails with linting errors
-- **Solution**: 
-  ```bash
-  make [local] format  # Auto-fix formatting
-  # Manually fix remaining linting issues
-  make [local] check   # Verify fixes
-  ```
-
-### Test Failures
-- **Problem**: Tests fail locally but pass in CI
-- **Solution**: 
-  ```bash
-  make [local] test    # Run in Docker container
-  ```
-
-- **Problem**: Tests fail with a VCS error:
-  ```bash
-  error obtaining VCS status: exit status 128
-  Use -buildvcs=false to disable VCS stamping.
-  ```
-- **Solution**:
-  Git security mechanisms prevent Golang from detecting the Git details inside
-  the container; either build with the `local` option, or pass GOFLAGS to
-  disable Golang buildvcs behaviour.
-  ```bash
-  make local test
-  # OR
-  make test GOFLAGS='-buildvcs=true'
-  ```
-
-### Documentation Generation Issues
-- **Problem**: Generated docs don't update after test changes
-- **Solution**: 
-  ```bash
-  cd pkg/yqlib
-  go test -run TestSpecificOperatorScenarios
-  # Check if generated file updated in pkg/yqlib/doc/
-  ```
-
-## Getting Help
-
-- **Check existing issues**: Search GitHub issues for similar problems
-- **Create an issue**: If you can't find a solution, create a detailed issue
-- **Ask questions**: Use GitHub Discussions for general questions
-- **Join the community**: Check the project's community channels
+- Update the `*.md` files
+- Raise a PR to merge the changes into gitbook.

-### Common Issues
-
-**PowerShell quoting issues:**
-```powershell
-# Use single quotes for expressions
-yq '.a.b[0].c' file.yaml
-
-# Or escape double quotes
-yq ".a.b[0].c = \"value\"" file.yaml
-```

-# Security Policy
-
-## Reporting a Vulnerability
-
-Please **do not** report security vulnerabilities through public GitHub issues.
-
-Instead, use GitHub's private vulnerability reporting feature:
-👉 https://github.com/mikefarah/yq/security
-
-This allows vulnerabilities to be triaged and addressed confidentially before any public disclosure.
-
-## Scope
-
-### HTTP / TLS / Network vulnerabilities
-
-yq is a command-line YAML/JSON/TOML processor that reads from files or standard input and writes to standard output. **yq does not include any HTTP or network libraries** and makes no network connections at runtime. CVEs related to HTTP, TLS, or networking are therefore **not applicable** to yq.
-
-### Dependency version bumps
-
-yq uses [Dependabot](https://docs.github.com/en/code-security/dependabot) to automatically raise pull requests for:
-
-- Go module dependencies
-- Go toolchain version
-- Docker base images
-
-Please **do not** raise pull requests or issues solely to bump dependency or Go versions — Dependabot handles this automatically and the maintainers merge those PRs regularly.

-# Expression Syntax: A Visual Guide
-In `yq`, expressions are made up of operators and pipes. A context of nodes is passed through the expression, and each operation takes the context as input and returns a new context as output. That output is piped in as input for the next operation in the expression.
+# How it works
 
-Let's break down the process step by step using a diagram. We'll start with a single YAML document, apply an expression, and observe how the context changes at each step.
+In `yq` expressions are made up of operators and pipes. A context of nodes is passed through the expression and each operation takes the context as input and returns a new context as output. That output is piped in as input for the next operation in the expression. To begin with, the context is set to the first yaml document of the first yaml file (if processing in sequence using eval).
 
-Given a document like:
-
-```yaml
-root:
-  items:
-    - name: apple
-      type: fruit
-    - name: carrot
-      type: vegetable
-    - name: banana
-      type: fruit
-```
-
-You can use dot notation to access nested structures. For example, to access the `name` of the first item, you would use the expression `.root.items[0].name`, which would return `apple`.
-
-But lets see how we could find all the fruit under `items`
-
-## Step 1: Initial Context
-The context starts at the root of the YAML document. In this case, the entire document is the initial context. 
-
-```
-root
-└── items
-    ├── name: apple
-    │   type: fruit
-    ├── name: carrot
-    │   type: vegetable
-    └── name: banana
-        type: fruit
-```
-
-## Step 2: Splatting the Array
-Using the expression `.root.items[]`, we "splat" the items array. This means each element of the array becomes its own node in the context:
-
-```
-Node 1: { name: apple, type: fruit }
-Node 2: { name: carrot, type: vegetable }
-Node 3: { name: banana, type: fruit }
-```
-
-## Step 3: Filtering the Nodes
-Next, we apply a filter to select only the nodes where type is fruit. The expression `.root.items[] | select(.type == "fruit")` filters the nodes:
-
-```
-Filtered Node 1: { name: apple, type: fruit }
-Filtered Node 2: { name: banana, type: fruit }
-```
-
-## Step 4: Extracting a Field
-Finally, we extract the name field from the filtered nodes using `.root.items[] | select(.type == "fruit") | .name` This results in:
-
-```
-apple
-banana
-```
+Lets look at a couple of examples.
