 ## Build and Development Process
 
 ### Prerequisites
+
 - Node.js 24+ (matches GitHub Actions runtime)
 - npm (included with Node.js)
 
 ### Essential Commands (ALWAYS run in this order)
 
 #### 1. Install Dependencies
+
 ```bash
 npm install
 ```
+
 **Timing**: ~20-30 seconds
 **Note**: Always run this first after cloning or when package.json changes
 
 #### 2. Build TypeScript
+
 ```bash
 npm run build
 ```
+
 **Timing**: ~5-10 seconds
 **Purpose**: Compiles TypeScript source to JavaScript in `lib/` directory
 
 #### 3. Lint and Format Code
+
 ```bash
 npm run check
 ```
+
 **Timing**: ~2-5 seconds
 **Tool**: Biome (replaces ESLint/Prettier)
 **Auto-fixes**: Formatting, import organization, basic linting issues
 
 #### 4. Package for Distribution
+
 ```bash
 npm run package
 ```
+
 **Timing**: ~20-30 seconds
 **Purpose**: Creates bundled distributions in `dist/` using @vercel/ncc
 **Critical**: This step MUST be run before committing - the `dist/` files are used by GitHub Actions
 
 #### 5. Run Tests
+
 ```bash
 npm test
 ```
+
 **Timing**: ~10-15 seconds
 **Framework**: Jest with TypeScript support
 **Coverage**: Unit tests for version resolution, input parsing, checksum validation
 
 #### 6. Complete Validation (Recommended)
+
 ```bash
 npm run all
 ```
+
 **Timing**: ~60-90 seconds
 **Purpose**: Runs build → check → package → test in sequence
 **Use**: Before making pull requests or when unsure about build state

 ## Troubleshooting
 
 ### Build Failures
+
 - **"Module not found"**: Run `npm install` to ensure dependencies are installed
 - **TypeScript errors**: Check `tsconfig.json` and ensure all imports are valid
 - **Test failures**: Check if test fixtures have been modified or if logic changes broke assumptions
 
 ### Action Failures in Workflows
+
 - **Changes not taking effect**: Ensure `npm run package` was run and `dist/` files committed
 - **Version resolution issues**: Check version specification format and file existence
 - **Cache problems**: Verify cache key generation and dependency glob patterns
 
 ### Common Gotchas
+
 - **Forgetting to package**: Code changes won't work without running `npm run package`
 - **Platform differences**: Windows paths use backslashes, test cross-platform behavior
 - **Cache invalidation**: Cache keys are sensitive to dependency file changes

-### Enable caching
-
-> [!NOTE]
-> The cache is pruned before it is uploaded to the GitHub Actions cache. This can lead to
-> a small or empty cache. See [Disable cache pruning](#disable-cache-pruning) for more details.
-
-If you enable caching, the [uv cache](https://docs.astral.sh/uv/concepts/cache/) will be uploaded to
-the GitHub Actions cache. This can speed up runs that reuse the cache by several minutes.
-Caching is enabled by default on GitHub-hosted runners.
-
-> [!TIP]
->
-> On self-hosted runners this is usually not needed since the cache generated by uv on the runner's
-> filesystem is not removed after a run. For more details see [Local cache path](#local-cache-path).
-
-You can optionally define a custom cache key suffix.
-
-```yaml
-- name: Enable caching and define a custom cache key suffix
-  id: setup-uv
-  uses: astral-sh/setup-uv@v6
-  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 example, to use the cache in the above case:
-
-```yaml
-- name: Do something if the cache was restored
-  if: steps.setup-uv.outputs.cache-hit == 'true'
-  run: echo "Cache was restored"
-```
-
-#### Cache dependency glob
-
-If you want to control when the GitHub Actions cache is invalidated, specify a glob pattern with the
-`cache-dependency-glob` input. The GitHub Actions cache will be invalidated if any file matching the glob pattern
-changes. If you use relative paths, they are relative to the repository root.

-  with:
-    enable-cache: true
-    cache-dependency-glob: "**/pyproject.toml"

-  with:
-    enable-cache: true
-    cache-dependency-glob: |
-      **/requirements*.txt
-      **/pyproject.toml
-```
-
-```yaml
-- name: Define an absolute cache dependency glob
-  uses: astral-sh/setup-uv@v6
-  with:
-    enable-cache: true
-    cache-dependency-glob: "/tmp/my-folder/requirements*.txt"
-```
-
-```yaml
-- name: Never invalidate the cache
-  uses: astral-sh/setup-uv@v6
-  with:
-    enable-cache: true
-    cache-dependency-glob: ""
-```
-
-#### Restore cache
-
-Restoring an existing cache can be enabled or disabled with the `restore-cache` input.
-By default, the cache will be restored.
-
-```yaml
-- name: Don't restore an existing cache
-  uses: astral-sh/setup-uv@v6
-  with:
-    enable-cache: true
-    restore-cache: false
-```
-
-#### Save cache
-
-You can also disable saving the cache after the run with the `save-cache` input.
-This can be useful to save cache storage when you know you will not use the cache of the run again.
-By default, the cache will be saved.
-
-```yaml
-- name: Don't save the cache after the run
-  uses: astral-sh/setup-uv@v6
-  with:
-    enable-cache: true
-    save-cache: false
-```
-
-### Local cache path
-
-If caching is enabled, this action controls where uv stores its cache on the runner's filesystem
-by setting `UV_CACHE_DIR`.
-
-It defaults to `setup-uv-cache` in the `TMP` dir, `D:\a\_temp\uv-tool-dir` on Windows and
-`/tmp/setup-uv-cache` on Linux/macOS. You can change the default by specifying the path with the
-`cache-local-path` input.
-
-> [!NOTE]
-> If the environment variable `UV_CACHE_DIR` is already set this action will not override it.
-> If you configured [cache-dir](https://docs.astral.sh/uv/reference/settings/#cache-dir) in your
-> config file then it is also respected and this action will not set `UV_CACHE_DIR`.
-
-```yaml
-- name: Define a custom uv cache path
-  uses: astral-sh/setup-uv@v6
-  with:
-    cache-local-path: "/path/to/cache"
-```
-
-### Disable cache pruning
-
-By default, the uv cache is pruned after every run, removing pre-built wheels, but retaining any
-wheels that were built from source. On GitHub-hosted runners, it's typically faster to omit those
-pre-built wheels from the cache (and instead re-download them from the registry on each run).
-However, on self-hosted or local runners, preserving the cache may be more efficient. See
-the [documentation](https://docs.astral.sh/uv/concepts/cache/#caching-in-continuous-integration) for
-more information.
-
-If you want to persist the entire cache across runs, disable cache pruning with the `prune-cache`
-input.
-
-```yaml
-- name: Don't prune the cache before saving it
-  uses: astral-sh/setup-uv@v6
-  with:
-    enable-cache: true
-    prune-cache: false
-```
-
-### Cache Python installs
-
-By default, the Python install dir (`uv python dir` / `UV_PYTHON_INSTALL_DIR`) is not cached,
-for the same reason that the dependency cache is pruned.
-If you want to cache Python installs along with your dependencies, set the `cache-python` input to `true`.
-
-```yaml
-- name: Cache Python installs
-  uses: astral-sh/setup-uv@v6
-  with:
-    enable-cache: true
-    cache-python: true
-```
-
-### Ignore nothing to cache
-
-By default, the action will fail if caching is enabled but there is nothing to upload (the uv cache directory does not exist).
-If you want to ignore this, set the `ignore-nothing-to-cache` input to `true`.
-
-```yaml
-- name: Ignore nothing to cache
-  uses: astral-sh/setup-uv@v6
-  with:
-    enable-cache: true
-    ignore-nothing-to-cache: true
-```
-
-### Ignore empty workdir
-
-By default, the action will warn if the workdir is empty, because this is usually the case when
-`actions/checkout` is configured to run after `setup-uv`, which is not supported.
-
-If you want to ignore this, set the `ignore-empty-workdir` input to `true`.
-
-```yaml
-- name: Ignore empty workdir
-  uses: astral-sh/setup-uv@v6
-  with:
-    ignore-empty-workdir: true
-```
-
-### GitHub authentication token
-
-This action uses the GitHub API to fetch the uv release artifacts. To avoid hitting the GitHub API
-rate limit too quickly, an authentication token can be provided via the `github-token` input. By
-default, the `GITHUB_TOKEN` secret is used, which is automatically provided by GitHub Actions.
-
-If the default
-[permissions for the GitHub token](https://docs.github.com/en/actions/security-for-github-actions/security-guides/automatic-token-authentication#permissions-for-the-github_token)
-are not sufficient, you can provide a custom GitHub token with the necessary permissions.
-
-```yaml
-- name: Install the latest version of uv with a custom GitHub token
-  uses: astral-sh/setup-uv@v6
-  with:
-    github-token: ${{ secrets.CUSTOM_GITHUB_TOKEN }}
-```
-
-### UV_TOOL_DIR
-
-On Windows `UV_TOOL_DIR` is set to `uv-tool-dir` in the `TMP` dir (e.g. `D:\a\_temp\uv-tool-dir`).
-On GitHub hosted runners this is on the much faster `D:` drive.
-
-On all other platforms the tool environments are placed in the
-[default location](https://docs.astral.sh/uv/concepts/tools/#tools-directory).
-
-If you want to change this behaviour (especially on self-hosted runners) you can use the `tool-dir`
-input:
-
-```yaml
-- name: Install the latest version of uv with a custom tool dir
-  uses: astral-sh/setup-uv@v6
-  with:
-    tool-dir: "/path/to/tool/dir"
-```
-
-### UV_TOOL_BIN_DIR
-
-On Windows `UV_TOOL_BIN_DIR` is set to `uv-tool-bin-dir` in the `TMP` dir (e.g.
-`D:\a\_temp\uv-tool-bin-dir`). On GitHub hosted runners this is on the much faster `D:` drive. This
-path is also automatically added to the PATH.
-
-On all other platforms the tool binaries get installed to the
-[default location](https://docs.astral.sh/uv/concepts/tools/#the-bin-directory).
-
-If you want to change this behaviour (especially on self-hosted runners) you can use the
-`tool-bin-dir` input:
-
-```yaml
-- name: Install the latest version of uv with a custom tool bin dir
-  uses: astral-sh/setup-uv@v6
-  with:
-    tool-bin-dir: "/path/to/tool-bin/dir"
-```
-
-### Tilde Expansion
-
-This action supports expanding the `~` character to the user's home directory for the following inputs:
-
-- `version-file`
-- `cache-local-path`
-- `tool-dir`
-- `tool-bin-dir`
-- `cache-dependency-glob`
-
-```yaml
-- name: Expand the tilde character
-  uses: astral-sh/setup-uv@v6
-  with:
-    cache-local-path: "~/path/to/cache"
-    tool-dir: "~/path/to/tool/dir"
-    tool-bin-dir: "~/path/to/tool-bin/dir"
-    cache-dependency-glob: "~/my-cache-buster"
-```
-
-### Manifest file
-
-The `manifest-file` input allows you to specify a JSON manifest that lists available uv versions,
-architectures, and their download URLs. By default, this action uses the manifest file contained
-in this repository, which is automatically updated with each release of uv.
-
-The manifest file contains an array of objects, each describing a version,
-architecture, platform, and the corresponding download URL. For example:
-
-```json
-[
-  {
-    "version": "0.7.13",
-    "artifactName": "uv-aarch64-apple-darwin.tar.gz",
-    "arch": "aarch64",
-    "platform": "apple-darwin",
-    "downloadUrl": "https://github.com/astral-sh/uv/releases/download/0.7.13/uv-aarch64-apple-darwin.tar.gz"
-  },
-  ...
-]
-```
-
-You can supply a custom manifest file URL to define additional versions,
-architectures, or different download URLs.
-This is useful if you maintain your own uv builds or want to override the default sources.
-
-```yaml
-- name: Use a custom manifest file
-  uses: astral-sh/setup-uv@v6
-  with:
-    manifest-file: "https://example.com/my-custom-manifest.json"
-```
-
-> [!NOTE]
-> When you use a custom manifest file and do not set the `version` input, its default value is `latest`.
-> This means the action will install the latest version available in the custom manifest file.
-> This is different from the default behavior of installing the latest version from the official uv releases.
-
-### Add problem matchers
-
-This action automatically adds
-[problem matchers](https://github.com/actions/toolkit/blob/main/docs/problem-matchers.md)
-for python errors.
-
-You can disable this by setting the `add-problem-matchers` input to `false`.
-
-```yaml
-- name: Install the latest version of uv without problem matchers
-  uses: astral-sh/setup-uv@v6
-  with:
-    add-problem-matchers: false
-```

+# Advanced Version Configuration
+
+This document covers advanced options for configuring which version of uv to install.
+
+## Install the latest version
+
+```yaml
+- name: Install the latest version of uv
+  uses: astral-sh/setup-uv@v6
+  with:
+    version: "latest"
+```
+
+## Install a specific version
+
+```yaml
+- name: Install a specific version of uv
+  uses: astral-sh/setup-uv@v6
+  with:
+    version: "0.4.4"
+```
+
+## Install a version by supplying a semver range or pep440 specifier
+
+You can specify a [semver range](https://github.com/npm/node-semver?tab=readme-ov-file#ranges)
+or [pep440 specifier](https://peps.python.org/pep-0440/#version-specifiers)
+to install the latest version that satisfies the range.
+
+```yaml
+- name: Install a semver range of uv
+  uses: astral-sh/setup-uv@v6
+  with:
+    version: ">=0.4.0"
+```
+
+```yaml
+- name: Pinning a minor version of uv
+  uses: astral-sh/setup-uv@v6
+  with:
+    version: "0.4.x"
+```
+
+```yaml
+- name: Install a pep440-specifier-satisfying version of uv
+  uses: astral-sh/setup-uv@v6
+  with:
+    version: ">=0.4.25,<0.5"
+```
+
+## Resolution strategy
+
+By default, when resolving version ranges, setup-uv will install the highest compatible version.
+You can change this behavior using the `resolution-strategy` input:
+
+```yaml
+- name: Install the lowest compatible version of uv
+  uses: astral-sh/setup-uv@v6
+  with:
+    version: ">=0.4.0"
+    resolution-strategy: "lowest"
+```
+
+The supported resolution strategies are:
+- `highest` (default): Install the latest version that satisfies the constraints
+- `lowest`: Install the oldest version that satisfies the constraints
+
+This can be useful for testing compatibility with older versions of uv, similar to uv's own `--resolution-strategy` option.
+
+## Install a version defined in a requirements or config file
+
+You can use the `version-file` input to specify a file that contains the version of uv to install.
+This can either be a `pyproject.toml` or `uv.toml` file which defines a `required-version` or
+uv defined as a dependency in `pyproject.toml` or `requirements.txt`.
+
+[asdf](https://asdf-vm.com/) `.tool-versions` is also supported, but without the `ref` syntax.
+
+```yaml
+- name: Install uv based on the version defined in pyproject.toml
+  uses: astral-sh/setup-uv@v6
+  with:
+    version-file: "pyproject.toml"
+```

+# Caching
+
+This document covers all caching-related configuration options for setup-uv.
+
+## Enable caching
+
+> [!NOTE]
+> The cache is pruned before it is uploaded to the GitHub Actions cache. This can lead to
+> a small or empty cache. See [Disable cache pruning](#disable-cache-pruning) for more details.
+
+If you enable caching, the [uv cache](https://docs.astral.sh/uv/concepts/cache/) will be uploaded to
+the GitHub Actions cache. This can speed up runs that reuse the cache by several minutes.
+Caching is enabled by default on GitHub-hosted runners.
+
+> [!TIP]
+>
+> On self-hosted runners this is usually not needed since the cache generated by uv on the runner's
+> filesystem is not removed after a run. For more details see [Local cache path](#local-cache-path).
+
+You can optionally define a custom cache key suffix.
+
+```yaml
+- name: Enable caching and define a custom cache key suffix
+  id: setup-uv
+  uses: astral-sh/setup-uv@v6
+  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 example, to use the cache in the above case:
+
+```yaml
+- name: Do something if the cache was restored
+  if: steps.setup-uv.outputs.cache-hit == 'true'
+  run: echo "Cache was restored"
+```
+
+## Cache dependency glob
+
+If you want to control when the GitHub Actions cache is invalidated, specify a glob pattern with the
+`cache-dependency-glob` input. The GitHub Actions cache will be invalidated if any file matching the glob pattern
+changes. If you use relative paths, they are relative to the repository root.
+
+> [!NOTE]
+>
+> You can look up supported patterns [here](https://github.com/actions/toolkit/tree/main/packages/glob#patterns)
+>
+> The default is
+> ```yaml
+> cache-dependency-glob: |
+>   **/*requirements*.txt
+>   **/*requirements*.in
+>   **/*constraints*.txt
+>   **/*constraints*.in
+>   **/pyproject.toml
+>   **/uv.lock
+>   **/*.py.lock
+> ```
+
+```yaml
+- name: Define a cache dependency glob
+  uses: astral-sh/setup-uv@v6
+  with:
+    enable-cache: true
+    cache-dependency-glob: "**/pyproject.toml"
+```
+
+```yaml
+- name: Define a list of cache dependency globs
+  uses: astral-sh/setup-uv@v6
+  with:
+    enable-cache: true
+    cache-dependency-glob: |
+      **/requirements*.txt
+      **/pyproject.toml
+```
+
+```yaml
+- name: Define an absolute cache dependency glob
+  uses: astral-sh/setup-uv@v6
+  with:
+    enable-cache: true
+    cache-dependency-glob: "/tmp/my-folder/requirements*.txt"
+```
+
+```yaml
+- name: Never invalidate the cache
+  uses: astral-sh/setup-uv@v6
+  with:
+    enable-cache: true
+    cache-dependency-glob: ""
+```
+
+## Restore cache
+
+Restoring an existing cache can be enabled or disabled with the `restore-cache` input.
+By default, the cache will be restored.
+
+```yaml
+- name: Don't restore an existing cache
+  uses: astral-sh/setup-uv@v6
+  with:
+    enable-cache: true
+    restore-cache: false
+```
+
+## Save cache
+
+You can also disable saving the cache after the run with the `save-cache` input.
+This can be useful to save cache storage when you know you will not use the cache of the run again.
+By default, the cache will be saved.
+
+```yaml
+- name: Don't save the cache after the run
+  uses: astral-sh/setup-uv@v6
+  with:
+    enable-cache: true
+    save-cache: false
+```
+
+## Local cache path
+
+If caching is enabled, this action controls where uv stores its cache on the runner's filesystem
+by setting `UV_CACHE_DIR`.
+
+It defaults to `setup-uv-cache` in the `TMP` dir, `D:\a\_temp\setup-uv-cache` on Windows and
+`/tmp/setup-uv-cache` on Linux/macOS. You can change the default by specifying the path with the
+`cache-local-path` input.
+
+> [!NOTE]
+> If the environment variable `UV_CACHE_DIR` is already set this action will not override it.
+> If you configured [cache-dir](https://docs.astral.sh/uv/reference/settings/#cache-dir) in your
+> config file then it is also respected and this action will not set `UV_CACHE_DIR`.
+
+```yaml
+- name: Define a custom uv cache path
+  uses: astral-sh/setup-uv@v6
+  with:
+    cache-local-path: "/path/to/cache"
+```
+
+## Disable cache pruning
+
+By default, the uv cache is pruned after every run, removing pre-built wheels, but retaining any
+wheels that were built from source. On GitHub-hosted runners, it's typically faster to omit those
+pre-built wheels from the cache (and instead re-download them from the registry on each run).
+However, on self-hosted or local runners, preserving the cache may be more efficient. See
+the [documentation](https://docs.astral.sh/uv/concepts/cache/#caching-in-continuous-integration) for
+more information.
+
+If you want to persist the entire cache across runs, disable cache pruning with the `prune-cache`
+input.
+
+```yaml
+- name: Don't prune the cache before saving it
+  uses: astral-sh/setup-uv@v6
+  with:
+    enable-cache: true
+    prune-cache: false
+```
+
+## Cache Python installs
+
+By default, the Python install dir (`uv python dir` / `UV_PYTHON_INSTALL_DIR`) is not cached,
+for the same reason that the dependency cache is pruned.
+If you want to cache Python installs along with your dependencies, set the `cache-python` input to `true`.
+
+```yaml
+- name: Cache Python installs
+  uses: astral-sh/setup-uv@v6
+  with:
+    enable-cache: true
+    cache-python: true
+```
+
+## Ignore nothing to cache
+
+By default, the action will fail if caching is enabled but there is nothing to upload (the uv cache directory does not exist).
+If you want to ignore this, set the `ignore-nothing-to-cache` input to `true`.
+
+```yaml
+- name: Ignore nothing to cache
+  uses: astral-sh/setup-uv@v6
+  with:
+    enable-cache: true
+    ignore-nothing-to-cache: true
+```

+# Customization
+
+This document covers advanced customization options including checksum validation, custom manifests, and problem matchers.
+
+## Validate checksum
+
+You can specify a checksum to validate the downloaded executable. Checksums up to the default version
+are automatically verified by this action. The sha256 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: astral-sh/setup-uv@v6
+  with:
+    version: "0.3.1"
+    checksum: "e11b01402ab645392c7ad6044db63d37e4fd1e745e015306993b07695ea5f9f8"
+```
+
+## Manifest file
+
+The `manifest-file` input allows you to specify a JSON manifest that lists available uv versions,
+architectures, and their download URLs. By default, this action uses the manifest file contained
+in this repository, which is automatically updated with each release of uv.
+
+The manifest file contains an array of objects, each describing a version,
+architecture, platform, and the corresponding download URL. For example:
+
+```json
+[
+  {
+    "version": "0.7.13",
+    "artifactName": "uv-aarch64-apple-darwin.tar.gz",
+    "arch": "aarch64",
+    "platform": "apple-darwin",
+    "downloadUrl": "https://github.com/astral-sh/uv/releases/download/0.7.13/uv-aarch64-apple-darwin.tar.gz"
+  },
+  ...
+]
+```
+
+You can supply a custom manifest file URL to define additional versions,
+architectures, or different download URLs.
+This is useful if you maintain your own uv builds or want to override the default sources.
+
+```yaml
+- name: Use a custom manifest file
+  uses: astral-sh/setup-uv@v6
+  with:
+    manifest-file: "https://example.com/my-custom-manifest.json"
+```
+
+> [!NOTE]
+> When you use a custom manifest file and do not set the `version` input, its default value is `latest`.
+> This means the action will install the latest version available in the custom manifest file.
+> This is different from the default behavior of installing the latest version from the official uv releases.
+
+## Add problem matchers
+
+This action automatically adds
+[problem matchers](https://github.com/actions/toolkit/blob/main/docs/problem-matchers.md)
+for python errors.
+
+You can disable this by setting the `add-problem-matchers` input to `false`.
+
+```yaml
+- name: Install the latest version of uv without problem matchers
+  uses: astral-sh/setup-uv@v6
+  with:
+    add-problem-matchers: false

+# Environment and Tools
+
+This document covers environment activation, tool directory configuration, and authentication options.
+
+## Activate environment
+
+You can set `activate-environment` to `true` to automatically activate a venv.
+This allows directly using it in later steps:
+
+```yaml
+- name: Install the latest version of uv and activate the environment
+  uses: astral-sh/setup-uv@v6
+  with:
+    activate-environment: true
+- run: uv pip install pip
+```
+
+> [!WARNING]
+>
+> Activating the environment adds your dependencies to the `PATH`, which could break some workflows.
+> For example, if you have a dependency which requires uv, e.g., `hatch`, activating the
+> environment will shadow the `uv` binary installed by this action and may result in a different uv
+> version being used.
+>
+> We do not recommend using this setting for most use-cases. Instead, use `uv run` to execute
+> commands in the environment.
+
+## GitHub authentication token
+
+This action uses the GitHub API to fetch the uv release artifacts. To avoid hitting the GitHub API
+rate limit too quickly, an authentication token can be provided via the `github-token` input. By
+default, the `GITHUB_TOKEN` secret is used, which is automatically provided by GitHub Actions.
+
+If the default
+[permissions for the GitHub token](https://docs.github.com/en/actions/security-for-github-actions/security-guides/automatic-token-authentication#permissions-for-the-github_token)
+are not sufficient, you can provide a custom GitHub token with the necessary permissions.
+
+```yaml
+- name: Install the latest version of uv with a custom GitHub token
+  uses: astral-sh/setup-uv@v6
+  with:
+    github-token: ${{ secrets.CUSTOM_GITHUB_TOKEN }}
+```
+
+## UV_TOOL_DIR
+
+On Windows `UV_TOOL_DIR` is set to `uv-tool-dir` in the `TMP` dir (e.g. `D:\a\_temp\uv-tool-dir`).
+On GitHub hosted runners this is on the much faster `D:` drive.
+
+On all other platforms the tool environments are placed in the
+[default location](https://docs.astral.sh/uv/concepts/tools/#tools-directory).
+
+If you want to change this behaviour (especially on self-hosted runners) you can use the `tool-dir`
+input:
+
+```yaml
+- name: Install the latest version of uv with a custom tool dir
+  uses: astral-sh/setup-uv@v6
+  with:
+    tool-dir: "/path/to/tool/dir"
+```
+
+## UV_TOOL_BIN_DIR
+
+On Windows `UV_TOOL_BIN_DIR` is set to `uv-tool-bin-dir` in the `TMP` dir (e.g.
+`D:\a\_temp\uv-tool-bin-dir`). On GitHub hosted runners this is on the much faster `D:` drive. This
+path is also automatically added to the PATH.
+
+On all other platforms the tool binaries get installed to the
+[default location](https://docs.astral.sh/uv/concepts/tools/#the-bin-directory).
+
+If you want to change this behaviour (especially on self-hosted runners) you can use the
+`tool-bin-dir` input:
+
+```yaml
+- name: Install the latest version of uv with a custom tool bin dir
+  uses: astral-sh/setup-uv@v6
+  with:
+    tool-bin-dir: "/path/to/tool-bin/dir"
+```
+
+## Tilde Expansion
+
+This action supports expanding the `~` character to the user's home directory for the following inputs:
+
+- `version-file`
+- `cache-local-path`
+- `tool-dir`
+- `tool-bin-dir`
+- `cache-dependency-glob`
+
+```yaml
+- name: Expand the tilde character
+  uses: astral-sh/setup-uv@v6
+  with:
+    cache-local-path: "~/path/to/cache"
+    tool-dir: "~/path/to/tool/dir"
+    tool-bin-dir: "~/path/to/tool-bin/dir"
+    cache-dependency-glob: "~/my-cache-buster"
+```
+
+## Ignore empty workdir
+
+By default, the action will warn if the workdir is empty, because this is usually the case when
+`actions/checkout` is configured to run after `setup-uv`, which is not supported.
+
+If you want to ignore this, set the `ignore-empty-workdir` input to `true`.
+
+```yaml
+- name: Ignore empty workdir
+  uses: astral-sh/setup-uv@v6
+  with:
+    ignore-empty-workdir: true
+```
+
+## Environment Variables
+
+This action sets several environment variables that influence uv's behavior and can be used by subsequent steps:
+
+- `UV_PYTHON`: Set when `python-version` input is specified. Controls which Python version uv uses.
+- `UV_CACHE_DIR`: Set when caching is enabled (unless already configured in uv config files). Controls where uv stores its cache.
+- `UV_TOOL_DIR`: Set when `tool-dir` input is specified. Controls where uv installs tool environments.
+- `UV_TOOL_BIN_DIR`: Set when `tool-bin-dir` input is specified. Controls where uv installs tool binaries.
+- `UV_PYTHON_INSTALL_DIR`: Always set. Controls where uv installs Python versions.
+- `VIRTUAL_ENV`: Set when `activate-environment` is true. Points to the activated virtual environment.
+
+**Environment variables that affect the action behavior:**
+
+- `UV_NO_MODIFY_PATH`: If set, prevents the action from modifying PATH. Cannot be used with `activate-environment`.
+- `UV_CACHE_DIR`: If already set, the action will respect it instead of setting its own cache directory.
+
+```yaml
+- name: Example using environment variables
+  uses: astral-sh/setup-uv@v6
+  with:
+    python-version: "3.12"
+    tool-dir: "/custom/tool/dir"
+    enable-cache: true
+
+- name: Check environment variables
+  run: |
+    echo "UV_PYTHON: $UV_PYTHON"
+    echo "UV_CACHE_DIR: $UV_CACHE_DIR"
+    echo "UV_TOOL_DIR: $UV_TOOL_DIR"
+    echo "UV_PYTHON_INSTALL_DIR: $UV_PYTHON_INSTALL_DIR"
+```
