 ## Usage
 
-Example workflow in a real world project can be found [here](https://github.com/eifinger/hass-weenect/blob/main/.github/workflows/ci.yml)
-
-### Install specific version
-
-You can also specify a specific version of uv
+### Install a required-version or latest (default)
 
 ```yaml
-- name: Install a specific version
-  uses: eifinger/setup-uv@v1
-  with:
-    version: '0.3.0'
+- name: Install the latest version of uv
+  uses: astral-sh/setup-uv@v5
 ```
 
-### Install latest version
+If you do not specify a version, this action will look for a [required-version](https://docs.astral.sh/uv/reference/settings/#required-version)
+in a `uv.toml` or `pyproject.toml` file in the repository root. If none is found, the latest version will be installed.
 
-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`.
+For an example workflow, see
+[here](https://github.com/charliermarsh/autobot/blob/e42c66659bf97b90ca9ff305a19cc99952d0d43f/.github/workflows/ci.yaml).
 
-> [!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.
+### Install the latest version
 
 ```yaml
-- name: Install a specific version
-  uses: eifinger/setup-uv@v1
+- name: Install the latest version of uv
+  uses: astral-sh/setup-uv@v5
   with:
-    version: 'latest'
+    version: "latest"
+```
+
+### Install a specific version
+
+```yaml
+- name: Install a specific version of uv
+  uses: astral-sh/setup-uv@v5
+  with:
+    version: "0.4.4"
+```
+
+### Install a version by supplying a semver range
+
+You can specify a [semver range](https://github.com/npm/node-semver?tab=readme-ov-file#ranges)
+to install the latest version that satisfies the range.
+
+```yaml
+- name: Install a semver range of uv
+  uses: astral-sh/setup-uv@v5
+  with:
+    version: ">=0.4.0"
+```
+
+```yaml
+- name: Pinning a minor version of uv
+  uses: astral-sh/setup-uv@v5
+  with:
+    version: "0.4.x"
+```
+
+### Install a required-version
+
+You can specify a [required-version](https://docs.astral.sh/uv/reference/settings/#required-version)
+in either a `uv.toml` or `pyproject.toml` file:
+
+```yaml
+- name: Install required-version defined in uv.toml
+  uses: astral-sh/setup-uv@v5
+  with:
+    uv-file: "path/to/uv.toml"

+  uses: astral-sh/setup-uv@v5
+  with:
+    pyproject-file: "path/to/pyproject.toml"
+```
+
+### Python version
+
+You can use the input `python-version` to
+
+- set the environment variable `UV_PYTHON` for the rest of your workflow
+- create a new virtual environment with the specified python version
+- activate the virtual environment for the rest of your workflow
+
+This will override any python version specifications in `pyproject.toml` and `.python-version`
+
+```yaml
+- name: Install the latest version of uv and set the python version to 3.13t
+  uses: astral-sh/setup-uv@v5
+  with:
+    python-version: 3.13t
+- run: uv pip install --python=3.13t pip
+```
+
+You can combine this with a matrix to test multiple python versions:
+
+```yaml
+jobs:
+  test:
+    runs-on: ubuntu-latest
+    strategy:
+      matrix:
+        python-version: ["3.9", "3.10", "3.11", "3.12"]
+    steps:
+      - uses: actions/checkout@v4
+      - name: Install the latest version of uv and set the python version

+      - name: Test with python ${{ matrix.python-version }}
+        run: uv run --frozen pytest
 ```
 
 ### 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.

 ### 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.
+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.
+
+> [!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

-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.
+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

+
+### Local cache path
+
+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.
 
 ```yaml
 - name: Define a custom uv cache path
-  uses: eifinger/setup-uv@v1
+  uses: astral-sh/setup-uv@v5
   with:
-    enable-cache: true
-    cache-local-path: '/path/to/cache'
+    cache-local-path: "/path/to/cache"
 ```
 
-#### Cache dependency glob
+### Disable cache pruning
 
-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.
+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: Define a cache dependency glob
-  uses: eifinger/setup-uv@v1
+- name: Don't prune the cache before saving it
+  uses: astral-sh/setup-uv@v5
   with:
     enable-cache: true
-    cache-dependency-glob: 'uv.lock'
+    prune-cache: false
 ```
 
+### 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: Define a cache dependency glob
-  uses: eifinger/setup-uv@v1
+- name: Ignore nothing to cache
+  uses: astral-sh/setup-uv@v5
   with:
     enable-cache: true
-    cache-dependency-glob: '**requirements*.txt'
+    ignore-nothing-to-cache: true
 ```
 
-### API rate limit
+### GitHub authentication token
 
-To avoid hitting the error `API rate limit exceeded` you can supply a GitHub token with the `github-token` input.
+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 uv and supply a GitHub token
-  uses: eifinger/setup-uv@v1
+- name: Install the latest version of uv with a custom GitHub token
+  uses: astral-sh/setup-uv@v5
   with:
-    github-token: ${{ secrets.GITHUB_TOKEN }}
+    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@v5
+  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@v5
+  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:
+
+- `cache-local-path`
+- `tool-dir`
+- `tool-bin-dir`
+- `cache-dependency-glob`
+
+```yaml
+- name: Expand the tilde character
+  uses: astral-sh/setup-uv@v5
+  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"
 ```
 
 ## 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.
+This action downloads uv from the uv repo's official
+[GitHub Releases](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`.
+The installed version of uv is then added to the runner PATH, enabling subsequent steps to invoke it
+by name (`uv`).
 
 ## FAQ
 
-### Do I still need actions/setup-python when using this action?
+### Do I still need `actions/setup-python` alongside `setup-uv`?
 
-No! This action was modelled as a drop-in replacement for `actions/setup-python` when using uv.
+With `setup-uv`, you can install a specific version of Python using `uv python install` rather than
+relying on `actions/setup-python`.
 
-A simple example workflow could look like this:
+Using `actions/setup-python` can be faster, because GitHub caches the Python versions alongside the runner.
+
+For example:

-  uses: eifinger/setup-uv@v1

   with:
     enable-cache: true
 - name: Test
-  run: uv run --frozen pytest
+  run: uv run --frozen pytest  # Uses the Python version automatically installed by uv
