-> ## :warning: Upgrade from v2!

-> The v2 version of this action [has stopped working](https://github.com/pnpm/action-setup/issues/135) with newer Node.js versions. Please, upgrade to the latest version to fix any issues.
+# Setup PNPM

-# Setup pnpm
-
-Install pnpm package manager.
+Install PNPM package manager.

 ## Inputs

 ### `version`

-Version of pnpm to install.
-
-**Optional** when there is a [`packageManager` field in the `package.json`](https://nodejs.org/api/corepack.html).
-
-otherwise, this field is **required** It supports npm versioning scheme, it could be an exact version (such as `6.24.1`), or a version range (such as `6`, `6.x.x`, `6.24.x`, `^6.24.1`, `*`, etc.), or `latest`.
+**Required** Version of PNPM to install.

 ### `dest`

-**Optional** Where to store pnpm files.
+**Optional** Where to store PNPM files.

-### `run_install`
+### `bin_dest`

-**Optional** (_default:_ `null`) If specified, run `pnpm install`.
+**Optional** Where to store executables (`pnpm` and `pnpx` commands).

-If `run_install` is either `null` or `false`, pnpm will not install any npm package.
+### `registry`

-If `run_install` is `true`, pnpm will install dependencies recursively.
-
-If `run_install` is a YAML string representation of either an object or an array, pnpm will execute every install commands.
-
-#### `run_install.recursive`
-
-**Optional** (_type:_ `boolean`, _default:_ `false`) Whether to use `pnpm recursive install`.
-
-#### `run_install.cwd`
-
-**Optional** (_type:_ `string`) Working directory when run `pnpm [recursive] install`.
-
-#### `run_install.args`
-
-**Optional** (_type:_ `string[]`) Additional arguments after `pnpm [recursive] install`, e.g. `[--ignore-scripts, --strict-peer-dependencies]`.
-
-### `cache`
-
-**Optional** (_type:_ `boolean`, _default:_ `false`) Whether to cache the pnpm store directory.
-
-### `cache_dependency_path`
-
-**Optional** (_type:_ `string|string[]`, _default:_ `pnpm-lock.yaml`) File path to the pnpm lockfile, which contents hash will be used as a cache key.
-
-### `package_json_file`
-
-**Optional** (_type:_ `string`, _default:_ `package.json`) File path to the `package.json`/[`package.yaml`](https://github.com/pnpm/pnpm/pull/1799) to read "packageManager" configuration.
-
-### `standalone`
-
-**Optional** (_type:_ `boolean`, _default:_ `false`) When set to true, [@pnpm/exe](https://www.npmjs.com/package/@pnpm/exe), which is a Node.js bundled package, will be installed, enabling using `pnpm` without Node.js.
-
-This is useful when you want to use a incompatible pair of Node.js and pnpm.
+**Optional** Registry to download PNPM from.

 ## Outputs

@ -68,100 +28,33 @@ Expanded path of inputs#dest.

 ### `bin_dest`

-Location of `pnpm` and `pnpx` command.
+Expanded path of inputs@bin_dest.

 ## Usage example

-### Install only pnpm without `packageManager`
-
-This works when the repo either doesn't have a `package.json` or has a `package.json` but it doesn't specify `packageManager`.

 ```

-###  Install only pnpm with `packageManager`
-
-Omit `version` input to use the version in the [`packageManager` field in the `package.json`](https://nodejs.org/api/corepack.html).
-
-```yaml
-on:
-  - push
-  - pull_request
-
-jobs:
-  install:
-    runs-on: ubuntu-latest
-
-    steps:
-      - uses: pnpm/action-setup@v5
-```
-
-### Install pnpm and a few npm packages
-
-```yaml
-on:
-  - push
-  - pull_request
-
-jobs:
-  install:
-    runs-on: ubuntu-latest
-
-    steps:
-      - uses: actions/checkout@v4
-
-      - uses: pnpm/action-setup@v5
-        with:
-          version: 10
-          run_install: |
-            - recursive: true
-              args: [--strict-peer-dependencies]
-            - args: [--global, gulp, prettier, typescript]
-```
-
-### Use cache to reduce installation time
-
-```yaml
-on:
-  - push
-  - pull_request
-
-jobs:
-  cache-and-install:
-    runs-on: ubuntu-latest
-
-    steps:
-      - name: Checkout
-        uses: actions/checkout@v4
-
-      - uses: pnpm/action-setup@v5
-        name: Install pnpm
-        with:
-          version: 10
-          cache: true
-
-      - name: Install dependencies
-        run: pnpm install
-```
-
-**Note:** You don't need to run `pnpm store prune` at the end; post-action has already taken care of that.
