 The action has built-in functionality for caching and restoring dependencies. It uses [toolkit/cache](https://github.com/actions/toolkit/tree/main/packages/cache) under the hood for caching dependencies but requires less configuration settings. Supported package managers are `pip`, `pipenv` and `poetry`. The `cache` input is optional, and caching is turned off by default.
 
-The action defaults to searching for a dependency file (`requirements.txt` for pip, `Pipfile.lock` for pipenv or `poetry.lock` for poetry) in the repository, and uses its hash as a part of the cache key. Input `cache-dependency-path` is used for cases when multiple dependency files are used, they are located in different subdirectories or different files for the hash that want to be used.

 ## Using `setup-python` on GHES
 
-`setup-python` comes pre-installed on the appliance with GHES if Actions is enabled. When dynamically downloading Python distributions, `setup-python` downloads distributions from [`actions/python-versions`](https://github.com/actions/python-versions) on github.com (outside of the appliance). These calls to `actions/python-versions` are made via unauthenticated requests, which are limited to [60 requests per hour per IP](https://docs.github.com/en/rest/overview/resources-in-the-rest-api#rate-limiting). If more requests are made within the time frame, then you will start to see rate-limit errors during downloading that looks like: `##[error]API rate limit exceeded for...`.
+### Avoiding rate limit issues
 
-To get a higher rate limit, you can [generate a personal access token on github.com](https://github.com/settings/tokens/new) and pass it as the `token` input for the action:
+`setup-python` comes pre-installed on the appliance with GHES if Actions is enabled. When dynamically downloading Python distributions, `setup-python` downloads distributions from [`actions/python-versions`](https://github.com/actions/python-versions) on github.com (outside of the appliance). These calls to `actions/python-versions` are by default made via unauthenticated requests, which are limited to [60 requests per hour per IP](https://docs.github.com/en/rest/overview/resources-in-the-rest-api#rate-limiting). If more requests are made within the time frame, then you will start to see rate-limit errors during downloading that look like this: 
+
+    ##[error]API rate limit exceeded for YOUR_IP. (But here's the good news: Authenticated requests get a higher rate limit. Check out the documentation for more details.)
+
+To get a higher rate limit, you can [generate a personal access token (PAT) on github.com](https://github.com/settings/tokens/new) and pass it as the `token` input for the action. It is important to understand that this needs to be a token from github.com and _not_ from your GHES instance. If you or your colleagues do not yet have a github.com account, you might need to create one.
+
+Here are the steps you need to follow to avoid the rate limit:
+
+1. Create a PAT on any github.com account by using [this link](https://github.com/settings/tokens/new) after logging into github.com (not your Enterprise instance).  This PAT does _not_ need any rights, so make sure all the boxes are unchecked.
+2. Store this PAT in the repository / organization where you run your workflow, e.g. as `GH_GITHUB_COM_TOKEN`. You can do this by navigating to your repository -> **Settings** -> **Secrets** -> **Actions** -> **New repository secret**.
+3. To use this functionality, you need to use any version newer than `v4.3`. Also, change _python-version_ as needed.
 
 ```yml
-uses: actions/setup-python@v4
+- name: Set up Python
-with:
+  uses: actions/setup-python@v4
-  token: ${{ secrets.GH_DOTCOM_TOKEN }}
+  with:
-  python-version: 3.11
+    python-version: 3.8
+    token: ${{ secrets.GH_GITHUB_COM_TOKEN }}
+```
+
+Requests should now be authenticated. To verify that you are getting the higher rate limit, you can call GitHub's [rate limit API](https://docs.github.com/en/rest/rate-limit) from within your workflow ([example](https://github.com/actions/setup-python/pull/443#issuecomment-1206776401)).
+
+### No access to github.com
+If the runner is not able to access github.com, any Python versions requested during a workflow run must come from the runner's tool cache. See "[Setting up the tool cache on self-hosted runners without internet access](https://docs.github.com/en/enterprise-server/admin/github-actions/managing-access-to-actions-from-githubcom/setting-up-the-tool-cache-on-self-hosted-runners-without-internet-access)" for more information.
+
+
+## Allow pre-releases
+
+The `allow-prereleases` flag defaults to `false`.
+If `allow-prereleases` is set to `true`, the action will allow falling back to pre-release versions of Python when a matching GA version of Python is not available.
+This allows for example to simplify reuse of `python-version` as an input of nox for pre-releases of Python by not requiring manipulation of the `3.y-dev` specifier.
+For CPython, `allow-prereleases` will only have effect for `x.y` version range (e.g. `3.12`).
+Let's say that python 3.12 is not generally available, the following workflow will fallback to the most recent pre-release of python 3.12:
+```yaml
+jobs:
+  test:
+    name: ${{ matrix.os }} / ${{ matrix.python_version }}
+    runs-on: ${{ matrix.os }}-latest
+    strategy:
+      fail-fast: false
+      matrix:
+        os: [Ubuntu, Windows, macOS]
+        python_version: ["3.11", "3.12"]
+
+    steps:
+      - uses: actions/checkout@v3
+      - uses: actions/setup-python@v4
+        with:
+          python-version: "${{ matrix.python_version }}"
+          allow-prereleases: true
+      - run: pipx run nox --error-on-missing-interpreters -s tests-${{ matrix.python_version }}
 ```
 
-If the runner is not able to access github.com, any Python versions requested during a workflow run must come from the runner's tool cache.

 - To implement new features or fix bugs, you need to make changes to the `.ts` files, which are located in the `src` folder
 - To comply with the code style, **you need to run the `format` script**
+- To lint the code, **you need to run the `lint:fix` script**
 - To transpile source code to `javascript` we use [NCC](https://github.com/vercel/ncc). **It is very important to run the `build` script after making changes**, otherwise your changes will not get into the final `javascript` build
 
 **Learn more about how to implement tests:**
