+# setup-texlive-action
+
+[![Marketplace][marketplace-badge]][marketplace]
+[![CI][ci-badge]][ci]
+[![Codecov][codecov-badge]][codecov]
+
+This action provides
+the functionality of installing and caching [TeX Live][texlive].
+
+Linux, Windows, and macOS are supported.
+
+## Usage
+
+Installing the latest version of TeX Live with `scheme-infraonly`:
+
+```yaml
+- name: Setup TeX Live
+  uses: teatimeguest/setup-texlive-action@v1
+
+- name: Check `tlmgr` version
+  run: tlmgr --version
+```
+
+Additional TeX packages to be installed
+can be specified by the `packages` input:
+
+```yaml
+- name: Setup TeX Live
+  uses: teatimeguest/setup-texlive-action@v1
+  with:
+    packages: >-
+      sheme-basic
+      cleveref
+      hyperref
+```
+
+An old version of TeX Live is also available:
+
+```yaml
+- name: Setup TeX Live 2019
+  uses: teatimeguest/setup-texlive-action@v1
+  with:
+    version: 2019
+```
+
+Versions prior to `2019` are currently not supported
+as the `install-tl` script does not work properly on Windows and macOS.
+
+## Caching
+
+By default, the action caches `TEXDIR` using [`@actions/cache`][actions-cache]
+to improve workflow execution time.
+If you want to disable caching, you can use the `cache` input:
+
+```yaml
+- name: Setup TeX Live
+  uses: teatimeguest/setup-texlive-action@v1
+  with:
+    cache: false
+```
+
+## Inputs
+
+All inputs are optional.
+
+|Name|Type|Description|
+|---|---|---|
+|`cache`|Bool|Enable to cache `TEXDIR`. The default is `true`.|
+|`packages`|String|Whitespace-separated list of TeX packages to install. Shemes and collections can also be specified.|
+|`prefix`|String|TeX Live installation prefix. The default is `C:\TEMP\setup-texlive` on Windows, `/tmp/setup-texlive` on Linux and macOS.|
+|`version`|String|Version of TeX Live to install. Supported values are `2019`, `2020`, `2021`, and `latest`.|
+
+## Outputs
+
+|Name|Type|Description|
+|---|---|---|
+|`cache-hit`|Bool|A boolean value to indicate if a cache was hit.|
