+# setup-uv
+
+Set up your GitHub Actions workflow with a specific version of [uv](https://docs.astral.sh/uv/).
+
+* Install a version of uv and add it to the path
+* Cache the installed version of uv to speed up consecutive runs on self-hosted runners
+* Register problem matchers for error output
+* Optional: Cache the uv cache
+* Optional: Verify the checksum of the downloaded uv executable
+
+## Usage
+
+Example workflow will be added later
+
+### Install specific version
+
+You can also specify a specific version of uv
+
+```yaml
+- name: Install a specific version
+  uses: eifinger/setup-uv@v1
+  with:
+    version: '0.3.0'
+```
+
+### Install latest version
+
+By default this action installs the version defined as `default` in `action.yml`.
+This gets automatically updated in a new release of this action when a new version of uv is released.
+If you don't want to wait for a new release of this action you can use use `version: latest`.
+
+> [!WARNING]  
+> Using the `latest` version means that the uv executable gets downloaded every single time instead of loaded from the tools cache.
+> This can take up to 20s depending on the download speed.
+> This does not affect the uv cache.
+
+```yaml
+- name: Install a specific version
+  uses: eifinger/setup-uv@v1
+  with:
+    version: 'latest'
+```
+
+### Validate checksum
+
+You can also specify a checksum to validate the downloaded file.
+Checksums up to the default version are automatically verified by this action.
+The sha265 hashes can be found on the [releases page](https://github.com/astral-sh/uv/releases)
+of the uv repo.
+
+```yaml
+- name: Install a specific version and validate the checksum
+  uses: eifinger/setup-uv@v1
+  with:
+    version: '0.3.1'
+    checksum: 'e11b01402ab645392c7ad6044db63d37e4fd1e745e015306993b07695ea5f9f8'
+```
+
+### Enable caching
+
+If you enable caching the [uv cache](https://docs.astral.sh/uv/concepts/cache/) will
+be cached to the GitHub Actions Cache. This can speed up runs which can reuse the cache
+by several minutes. The cache will always be reused on self-hosted runners.
+
+You can optionally define a custom cache key suffix.
+
+```yaml
+- name: Enable caching and define a custom cache key suffix
+  id: setup-uv
+  uses: eifinger/setup-uv@v1
+  with:
+    enable-cache: true
+    cache-suffix: 'optional-suffix'
+```
+
+When the cache was successfully restored the output `cache-hit` will be set to `true` and you can use it in subsequent steps.
+For the example above you can use it like this:
+
+```yaml
+- name: Do something if the cache was restored
+  if: steps.setup-uv.outputs.cache-hit == 'true'
+  run: echo "Cache was restored"
+```
+
+#### Local cache path
+
+If you want to save the cache to a local path other than the default path (`/tmp/setup-uv-cache`)
+you can specify the path with the `cache-local-path` input.
+
+```yaml
+- name: Define a custom uv cache path
+  uses: eifinger/setup-uv@v1
+  with:
+    enable-cache: true
+    cache-local-path: '/path/to/cache'
+```
+
+#### Cache dependency glob
+
+If you want to control when the cache is invalidated you can specify a glob pattern with the `cache-dependency-glob` input.
+The cache will be invalidated if any file matching the glob pattern changes.
+The glob matches files relative to the repository root.
+
+```yaml
+- name: Define a custom cache dependency glob
+  uses: eifinger/setup-uv@v1
+  with:
+    enable-cache: true
+    cache-dependency-glob: 'uv.lock'
+```
+
+```yaml
+- name: Define a custom cache dependency glob
+  uses: eifinger/setup-uv@v1
+  with:
+    enable-cache: true
+    cache-dependency-glob: '**requirements*.txt'
+```
+
+### API rate limit
+
+To avoid hitting the error `API rate limit exceeded` you can supply a GitHub token with the `github-token` input.
+
+```yaml
+- name: Install uv and supply a GitHub token
+  uses: eifinger/setup-uv@v1
+  with:
+    github-token: ${{ secrets.GITHUB_TOKEN }}
+```
+
+## How it works
+
+This action downloads uv from the releases of the [uv repo](https://github.com/astral-sh/uv) and uses the [GitHub Actions Toolkit](https://github.com/actions/toolkit) to cache it as a tool to speed up consecutive runs on self-hosted runners.
+
+The installed version of uv is then added to the runner path so other steps can just use it by calling `uv`.
+
+## FAQ
+
+### Do I still need actions/setup-python when using this action?
+
+No! This action was modelled as a drop-in replacement for `actions/setup-python` when using uv.
+
+A simple example workflow could look like this:
+
+```yaml
+- name: Checkout the repository
+  uses: actions/checkout@main
+- name: Install the latest version of uv
+  uses: eifinger/setup-uv@v1
+  with:
+    enable-cache: true
+- name: Sync dependencies
+  run: uv sync
+- name: Test
+  run: uv run pytest
+```
+
+### What is the default version?
+
+By default this action installs the version defined as `default` in `action.yml`.
+When a new release of uv is published this triggers an automatic release of this action with the new version as `default`.
+
+If you have to know the version installed for other steps of your workflow you can use the `uv-version` output:
+
+```yaml
+- name: Checkout the repository
+  uses: actions/checkout@latest
+- name: Install the default version of uv
+  id: setup-uv
+  uses: eifinger/setup-uv@v1
+- name: Print the installed version
+  run: echo "Installed uv version is ${{ steps.setup-uv.outputs.uv-version }}"
+```
