Bump version

There has been a security issue with older Alpine versions and their package manager.
https://justi.cz/security/2018/09/13/alpine-apk-rce.html

Not sure about 3.7, but the latest 3.8 image has it fixed.

-# yq
+# yq 
 
-a lightweight and portable command-line YAML, JSON, INI and XML processor. `yq` uses [jq](https://github.com/stedolan/jq) like syntax but works with yaml files as well as json, xml, ini, properties, csv and tsv. It doesn't yet support everything `jq` does - but it does support the most common operations and functions, and more is being added continuously.
+[![Build Status](https://travis-ci.org/mikefarah/yq.svg?branch=master)](https://travis-ci.org/mikefarah/yq)  ![Docker Pulls](https://img.shields.io/docker/pulls/mikefarah/yq.svg) ![Github Releases (by Release)](https://img.shields.io/github/downloads/mikefarah/yq/total.svg)
 
-yq is written in go - so you can download a dependency free binary for your platform and you are good to go! If you prefer there are a variety of package managers that can be used as well as Docker and Podman, all listed below.
 
-## Quick Usage Guide
+a lightweight and portable command-line YAML processor
 
-Read a value:
-```bash
-yq '.a.b[0].c' file.yaml
-```
-
-Pipe from STDIN:
-```bash
-yq '.a.b[0].c' < file.yaml
-```
-
-Update a yaml file, in place
-```bash
-yq -i '.a.b[0].c = "cool"' file.yaml
-```
-
-Update using environment variables
-```bash
-NAME=mike yq -i '.a.b[0].c = strenv(NAME)' file.yaml
-```
-
-Merge multiple files
-```bash
-# merge two files
-yq -n 'load("file1.yaml") * load("file2.yaml")'
-
-# merge using globs:
-# note the use of `ea` to evaluate all the files at once
-# instead of in sequence
-yq ea '. as $item ireduce ({}; . * $item )' path/to/*.yml
-```
-
-Multiple updates to a yaml file
-```bash
-yq -i '
-  .a.b[0].c = "cool" |
-  .x.y.z = "foobar" |
-  .person.name = strenv(NAME)
-' file.yaml
-```
-
-Find and update an item in an array:
-```bash
-yq '(.[] | select(.name == "foo") | .address) = "12 cat st"'
-```
-
-Convert JSON to YAML
-```bash
-yq -Poy sample.json
-```
-
-See [recipes](https://mikefarah.gitbook.io/yq/recipes) for more examples and the [documentation](https://mikefarah.gitbook.io/yq/) for more information.
-
-Take a look at the discussions for [common questions](https://github.com/mikefarah/yq/discussions/categories/q-a), and [cool ideas](https://github.com/mikefarah/yq/discussions/categories/show-and-tell)
+The aim of the project is to be the [jq](https://github.com/stedolan/jq) or sed of yaml files.
 
 ## Install
+On MacOS:
+```
+brew install yq
+```
+On Ubuntu and other Linux distros supporting `snap` packages:
+```
+snap install yq
+```
+On Ubuntu 16.04 or higher from Debian package:

+```
 
-See the [github page](https://github.com/mikefarah/yq/#install) for the various ways you can install and use `yq`
+## Run with Docker
 
-## Known Issues / Missing Features
-- `yq` attempts to preserve comment positions and whitespace as much as possible, but it does not handle all scenarios (see https://github.com/go-yaml/yaml/tree/v3 for details)
-- Powershell has its own...[opinions on quoting yq](https://mikefarah.gitbook.io/yq/usage/tips-and-tricks#quotes-in-windows-powershell)
+Oneshot use:
 
-See [tips and tricks](https://mikefarah.gitbook.io/yq/usage/tips-and-tricks) for more common problems and solutions.

----
-
-# Evaluate All
-
-Evaluate All is most useful when needing to run expressions that depend on multiple yaml documents or files. Merge is probably the most common reason why evaluate all would be used. Note that `eval-all` consumes more memory than `evaluate`.
-
-Like `evaluate` you can use `-` to pipe from STDIN.
-
-## Usage
-
-```bash
-yq eval-all [expression] [yaml_file1]... [flags]
-```
-
-Aliases: `eval-all, ea`
-
-## Examples
-
-```bash
-# merges f2.yml into f1.yml (inplace)
-yq eval-all --inplace 'select(fileIndex == 0) * select(fileIndex == 1)' f1.yml f2.yml
-
-# you can merge into a file, piping from STDIN
-cat somefile.yml | yq eval-all --inplace 'select(fileIndex == 0) * select(fileIndex == 1)' f1.yml -
-```
-
-## Flags
-
-```bash
-  -h, --help          help for eval-all
-  -C, --colors        force print with colors
-  -e, --exit-status   set exit status if there are no matches or null or false is returned
-  -I, --indent int    sets indent level for output (default 2)
-  -i, --inplace       update the yaml file inplace of first yaml file given.
-  -M, --no-colors     force print with no colors
-  -N, --no-doc        Don't print document separators (---)
-  -n, --null-input    Don't read input, simply evaluate the expression given. Useful for creating yaml docs from scratch.
-  -j, --tojson        output as json. Set indent to 0 to print json in one line.
-  -v, --verbose       verbose mode

-```bash
-# runs the expression against each file, in series

-# '-' will pipe from STDIN

-### zsh
-
-If shell completion is not already enabled in your environment you will need to enable it.  You can execute the following once:
-
-```bash
-echo "autoload -U compinit; compinit" >> ~/.zshrc
-```
-
-#### To load completions for each session, execute once:
-
-```bash
-yq shell-completion zsh > "${fpath[1]}/_yq"
-```
-
-You will need to start a new shell for this setup to take effect.
-
-### fish
-
-```bash
-yq shell-completion fish | source

-
-#### To load completions for each session, execute once:
-
-```
-yq shell-completion fish > ~/.config/fish/completions/yq.fish
-```
-
-### PowerShell
-
-```bash
-yq shell-completion powershell
-```
-
-Users need PowerShell version 5.0 or above, which comes with Windows 10 and can be downloaded separately for Windows 7 or 8.1. They can then write the completions to a file and source this file from their PowerShell profile, which is referenced by the $Profile environment variable.

+<p>To convert output to json, use the --tojson (or -j) flag. This can only be used with the read command.</p>
+<p>Given a sample.yaml file of:</p>
+<pre><code class="yaml">b:
+  c: 2
+</code></pre>
+
+<p>then</p>
+<pre><code class="bash">yq r -j sample.yaml b.c
+</code></pre>
+
+<p>will output</p>
+<pre><code class="json">{&quot;b&quot;:{&quot;c&quot;:2}}
+</code></pre>
+
+<h3 id="json-to-yaml">Json to Yaml<a class="headerlink" href="#json-to-yaml" title="Permanent link">&para;</a></h3>
+<p>To read in json, just pass in a json file instead of yaml, it will just work :)</p>
+<p>e.g given a json file</p>
+<pre><code class="json">{&quot;a&quot;:&quot;Easy! as one two three&quot;,&quot;b&quot;:{&quot;c&quot;:2,&quot;d&quot;:[3,4]}}

+                <p>Yaml files can be created using the 'new' command. This works in the same way as the write command, but you don't pass in an existing Yaml file. Currently this does not support creating multiple documents in a single yaml file.</p>

+</code></pre>
+
+<h3 id="creating-a-simple-yaml-file">Creating a simple yaml file<a class="headerlink" href="#creating-a-simple-yaml-file" title="Permanent link">&para;</a></h3>
+<pre><code class="bash">yq n b.c cat
+</code></pre>
+
+<p>will output:</p>

+
+<h3 id="creating-using-a-create-script">Creating using a create script<a class="headerlink" href="#creating-using-a-create-script" title="Permanent link">&para;</a></h3>
+<p>Create scripts follow the same format as the update scripts.</p>
+<p>Given a script create_instructions.yaml of:</p>
+<pre><code class="yaml">b.c: 3
+b.e[0].name: Howdy Partner
+</code></pre>
+
+<p>then</p>
+<pre><code class="bash">yq n -s create_instructions.yaml
+</code></pre>
+
+<p>will output:</p>
+<pre><code class="yaml">b:
+  c: 3
+  e:
+    - name: Howdy Partner
+</code></pre>
+
+<p>You can also pipe the instructions in:</p>
+<pre><code class="bash">cat create_instructions.yaml | yq n -s -
+</code></pre>
+
+<h3 id="keys-with-dots">Keys with dots<a class="headerlink" href="#keys-with-dots" title="Permanent link">&para;</a></h3>
+<p>When specifying a key that has a dot use key lookup indicator.</p>
+<pre><code class="yaml">b:
+  foo.bar: 7
+</code></pre>
+
+<pre><code class="bash">yaml r sample.yaml 'b[foo.bar]'
+</code></pre>
+
+<pre><code class="bash">yaml w sample.yaml 'b[foo.bar]' 9
+</code></pre>
+
+<p>Any valid yaml key can be specified as part of a key lookup.</p>
+<p>Note that the path is in quotes to avoid the square brackets being interpreted by your shell.</p>

-# 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.
-
-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.
-
-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
-```
-
-## Simple assignment example
-
-Given a document like:
-
-```yaml
-a: cat
-b: dog
-```
-
-with an expression:
-
-```
-.a = .b
-```
-
-Like math expressions - operator precedence is important. 
-
-The `=` operator takes two arguments, a `lhs` expression, which in this case is `.a` and `rhs` expression which is `.b`. 
-
-It pipes the current, lets call it 'root' context through the `lhs` expression of `.a` to return the node 
-
-```yaml
-cat
-```
-
-Side note: this node holds not only its value 'cat', but comments and metadata too, including path and parent information.
-
-The `=` operator then pipes the 'root' context through the `rhs` expression of `.b` to return the node
-
-```yaml
-dog
-```
-
-Both sides have now been evaluated, so now the operator copies across the value from the RHS (`.b`) to the LHS (`.a`), and it returns the now updated context:
-
-```yaml
-a: dog
-b: dog
-```
-
-## Complex assignment, operator precedence rules
-
-Just like math expressions - `yq` expressions have an order of precedence. The pipe `|` operator has a low order of precedence, so operators with higher precedence will get evaluated first. 
-
-Most of the time, this is intuitively what you'd want, for instance `.a = "cat" | .b = "dog"` is effectively: `(.a = "cat") | (.b = "dog")`.
-
-However, this is not always the case, particularly if you have a complex LHS or RHS expression, for instance if you want to select particular nodes to update. 
-
-Lets say you had:
-
-```yaml
-- name: bob
-  fruit: apple
-- name: sally
-  fruit: orange
-
-```
-
-Lets say you wanted to update the `sally` entry to have fruit: 'mango'. The _incorrect_ way to do that is:
-`.[] | select(.name == "sally") | .fruit = "mango"`.
-
-Because `|` has a low operator precedence, this will be evaluated (_incorrectly_) as : `(.[]) | (select(.name == "sally")) | (.fruit = "mango")`. What you'll see is only the updated segment returned:
-
-```yaml
-name: sally
-fruit: mango
-```
-
-**Important**: To properly update this YAML, you must wrap the entire LHS in parentheses. Think of it like using brackets in math to ensure the correct order of operations.
-`(.[] | select(.name == "sally") | .fruit) = "mango"`
-
-
-Now that entire LHS expression is passed to the 'assign' (`=`) operator, and the yaml is correctly updated and returned:
-
-
-```yaml
-- name: bob
-  fruit: apple
-- name: sally
-  fruit: mango
-
-```
-
-## Relative update (e.g. `|=`)
-There is another form of the `=` operator which we call the relative form. It's very similar to `=` but with one key difference when evaluating the RHS expression.
-
-In the plain form, we pass in the 'root' level context to the RHS expression. In relative form, we pass in _each result of the LHS_ to the RHS expression. Let's go through an example.
-
-Given a document like:
-
-```yaml
-a: 1
-b: thing
-```
-
-with an expression:
-
-```
-.a |= . + 1
-```
-
-Similar to the `=` operator, `|=` takes two operands, the LHS and RHS.
-
-It pipes the current context (the whole document) through the LHS expression of `.a` to get the node value:
-
-```
-1
-```
-
-Now it pipes _that LHS context_ into the RHS expression `. + 1` (whereas in the `=` plain form it piped the original document context into the RHS) to yield:
-
-
-```
-2
-```
-
-The assignment operator then copies across the value from the RHS to the value on the LHS, and it returns the now updated 'root' context:
-
-```yaml
-a: 2
-b: thing
-```
