 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
+
+`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
+- name: Set up Python
+  uses: actions/setup-python@v4
+  with:
+    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 }}
+```
 
-To avoid hitting rate-limit problems, we recommend [setting up your own runner tool cache](https://docs.github.com/en/enterprise-server@2.22/admin/github-actions/managing-access-to-actions-from-githubcom/setting-up-the-tool-cache-on-self-hosted-runners-without-internet-access#about-the-included-setup-actions-and-the-runner-tool-cache).

+Thank you for contributing!
 
-- Do check in source (`src/`)
-- Do check in a single `index.js` file after running `ncc`
-- Do not check in `node_modules/`
+We have prepared a short guide so that the process of making your contribution is as simple and clear as possible. Please check it out before you contribute!
 
-### NCC
+## How can I contribute...
 
-In order to avoid uploading `node_modules/` to the repository, we use [vercel/ncc](https://github.com/vercel/ncc) to create a single `index.js` file that gets saved in `dist/`.
+* [Contribute Documentation:green_book:](#contribute-documentation)
 
-### Developing
+* [Contribute Code :computer:](#contribute-code)
 
-If you're developing locally, you can run
+* [Provide Support on Issues:pencil:](#provide-support-on-issues)
 
-```sh
-npm install
-tsc
-ncc build src/setup-python.ts
-```
+* [Review Pull Requests:mag:](#review-pull-requests)
 
-Any files generated using `tsc` will be added to `lib/`, however those files also are not uploaded to the repository and are excluded using `.gitignore`.
+## Contribute documentation
 
-During the commit step, Husky will take care of formatting all files with [Prettier](https://github.com/prettier/prettier) (to run manually, use `npm run format`).
+Documentation is a super important, critical part of this project. Docs are how we keep track of what we're doing, how, and why. It's how we stay on the same page about our policies and how we tell others everything they need to be able to use this project or contribute to it. 
 
-### Testing
+Documentation contributions of any size are welcome! Feel free to contribute even if you're just rewording a sentence to be more clear, or fixing a spelling mistake!
 
-We ask that you include a link to a successful run that utilizes the changes you are working on. For example, if your changes are in the branch `newAwesomeFeature`, then show an example run that uses `setup-python@newAwesomeFeature` or `my-fork@newAwesomeFeature`. This will help speed up testing and help us confirm that there are no breaking changes or bugs.
+**How to contribute:**
 
-### Licensed
+Pull requests are the easiest way to contribute changes to git repos at GitHub. They are the preferred contribution method, as they offer a convenient way of commenting and amending the proposed changes.
 
-This repository uses a tool called [Licensed](https://github.com/github/licensed) to verify third party dependencies. You may need to locally install licensed and run `licensed cache` to update the dependency cache if you install or update a production dependency. If licensed cache is unable to determine the dependency, you may need to modify the cache file yourself to put the correct license. You should still verify the dependency, licensed is a tool to help, but is not a substitute for human review of dependencies.
+- Please check that no one else has already created a pull request with these or similar changes
+- Use a "feature branch" for your changes. That separates the changes in the pull request from your other changes and makes it easy to edit/amend commits in the pull request 
+- Make sure your changes are formatted properly and consistently with the rest of the documentation
+- Re-read what you wrote, and run a spellchecker on it to make sure you didn't miss anything
+- If your pull request is connected to an open issue, please, leave a link to this issue in the `Related issue:` section
+- If you later need to add new commits to the pull request, you can simply commit the changes to the local branch and then push them. The pull request gets automatically updated
 
-### Releases
+**Once you've filed the pull request:**
 
-There is a `master` branch where contributor changes are merged into. There are also release branches such as `releases/v1` that are used for tagging (for example the `v1` tag) and publishing new versions of the action. Changes from `master` are periodically merged into a releases branch. You do not need to create any PR that merges changes from master into a releases branch.
+- Maintainers will review your pull request
+- If a maintainer requests changes, first of all, try to think about this request critically and only after that implement and request another review
+- If your PR gets accepted, it will soon be merged into the main branch. But your contribution will take effect only after the release of a new version of the action and updating the major tag
+> Sometimes maintainers reject pull requests and that's ok! Usually, along with rejection, we supply the reason for it. Nonetheless, we still really appreciate you taking the time to do it, and we don't take that lightly :heart:
+
+## Contribute code
+
+We like code commits a lot! They're super handy, and they keep the project going and doing the work it needs to do to be useful to others.
+
+Code contributions of just about any size are acceptable!
+
+The main difference between code contributions and documentation contributions is that contributing code requires the inclusion of relevant tests for the code being added or changed. Contributions without accompanying tests will be held off until a test is added unless the maintainers consider the specific tests to be either impossible or way too much of a burden for such a contribution.
+
+**How to contribute:**
+
+Pull requests are the easiest way to contribute changes to git repos at GitHub. They are the preferred contribution method, as they offer a convenient way of commenting and amending the proposed changes.
+
+- Please check that no one else has already created a pull request with these or similar changes
+- Use a "feature branch" for your changes. That separates the changes in the pull request from your other changes and makes it easy to edit/amend commits in the pull request
+- Make sure your changes are well formatted and that all tests are passing
+- If your pull request is connected to an open issue, please, leave a link to this issue in the `Related issue:` section
+- If you later need to add new commits to the pull request, you can simply commit the changes to the local branch and then push them. The pull request gets automatically updated
+
+**Learn more about how to work with the repository:**
+
+- 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:**
+
+Adding or changing tests is an integral part of making a change to the code. 
+Unit tests are in the `__tests__` folder, and end-to-end tests are in the `workflows` folder, particularly take a look at the files with `e2e` and `test` prefixes, for instance, [e2e-cache.yml](https://github.com/actions/setup-python/blob/main/.github/workflows/e2e-cache.yml).
+
+- The contributor can add various types of tests (like unit tests or end-to-end tests), which, in his opinion, will be necessary and sufficient for testing new or changed functionality
+- Tests should cover a successful execution, as well as some edge cases and possible errors
+- As already mentioned, pull requests without tests will be considered more carefully by maintainers. If you are sure that in this situation the tests are not needed or cannot be implemented with a commensurate effort - please add this clarification message to your pull request
+
+**Once you've filed the pull request:**
+
+- CI will start automatically with some checks. Wait until the end of the execution and make sure that all checks passed successfully. If some checks fail, you can open them one by one, try to find the reason for failing and make changes to your code to resolve the problem
+- Maintainers will review your pull request
+- If a maintainer requests changes, first of all, try to think about his request critically and only after that implement and request another review

+
+## Provide support on issues
+
+Helping out other users with their questions is an awesome way of contributing to any community. It's not uncommon for most of the issues on open source projects to be support-related questions by users trying to understand something they ran into or find their way around a known bug.
+
+**To help other folks out with their questions:**
+
+- Go to the [issue tracker](https://github.com/actions/setup-python/issues)
+- Read through the list until you find something that you're familiar enough with to answer to
+- Respond to the issue with whatever details are needed to clarify the question, or get more details about what's going on
+- Once the discussion wraps up and things are clarified, ask the original issue filer (or a maintainer) to close it for you
+ 
+*Some notes on picking up support issues:*
+
+- Avoid responding to issues you don't know you can answer accurately
+- Try to refer to past issues with accepted answers as much as possible. Link to them from your replies
+- Be kind and patient with users. Often, folks who have run into confusing things might be upset or impatient. This is natural. If you feel uncomfortable in conversation with them, it's better to stay away or withdraw from the issue.
+
+ > If some user is violating our code of conduct [standards](https://github.com/actions/setup-python/blob/main/CODE_OF_CONDUCT.md#our-standards), refer to the [enforcement](https://github.com/actions/setup-python/blob/main/CODE_OF_CONDUCT.md#enforcement) section of the Code of Conduct to resolve the conflict
+ 
+
+## Review pull requests
+ 
+
+Another great way to contribute is to review pull request. Please, be extra kind: people who submit code/doc contributions are putting themselves in a pretty vulnerable position, and have put time and care into what they've done (even if that's not obvious to you!) Please, always respond with respect, and be understanding, but don't feel like you need to sacrifice your standards for their sake, either.
+ 
+**How to review:**
+
+- Go to the [pull requests](https://github.com/actions/setup-python/pulls)
+- Make sure you're familiar with the code or documentation is updated, unless it's a minor change (spellchecking, minor formatting, etc.)
+- Review changes using the GitHub functionality. You can ask a clarifying question, point out an error or suggest an alternative. 
+> Note: You may ask for minor changes - "nitpicks", but consider whether they are real blockers to merging or not
+- Submit your review, which may include comments, an approval, or a changes request
