-### Checkin
-
-- Do checkin source (src)
-- Do checkin a single index.js file after running `ncc`
-- Do not checking node_modules
-
-### NCC
-
-In order to avoid uploading `node_modules` to the repository, we use [vercel/ncc](https://github.com/vercel/ncc) to create multiple `index.js` files that gets saved under `dist/`.
-There are two main files that get created
-- `dist/setup/index.js`
-   - Core `setup-java` logic that downloads and installs an appropriate version of Java 
-   - Handling creating a `settings.xml` file to make it easier to publish packages
-- `dist/cleanup/index/js`
-   -  Extra cleanup script that is used to remove GPG keys (needed for certain self-hosted runner scenarios)
-
-If you're developing locally, after doing `npm install`, you can use the following commands
-```yaml
-npm run build # runs tsc along with ncc
-npm run format # runs prettier --write
-npm run format-check # runs prettier --check
-npm run test # runs jest
-npm run release # add all the necessary ncc files under dist/* to the git staging area
-```
-
-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`.
-
-### Testing
-
-Tests are included under `_tests_/*` and can be run using `npm run-script test`.
-
-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.
-
-### Licensed
-
-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.

 ## Usage
-Inputs `java-version` and `distribution` are mandatory. See [Supported distributions](#supported-distributions) section for a list of available options.
 
-### Basic
-**Eclipse Temurin**
+  - `java-version`: The Java version that is going to be set up. Takes a whole or [semver](#supported-version-syntax) Java version. If not specified, the action will expect `java-version-file` input to be specified.
+
+  - `java-version-file`: The path to the `.java-version` file. See more details in [about `.java-version` file](docs/advanced-usage.md#Java-version-file).
+   
+  - `distribution`: _(required)_ Java [distribution](#supported-distributions).
+
+  - `java-package`: The packaging variant of the choosen distribution. Possible values: `jdk`, `jre`, `jdk+fx`, `jre+fx`. Default value: `jdk`.
+
+  - `architecture`: The target architecture of the package. Possible values: `x86`, `x64`, `armv7`, `aarch64`, `ppc64le`. Default value: Derived from the runner machine.
+
+  - `jdkFile`: If a use-case requires a custom distribution setup-java uses the compressed JDK from the location pointed by this input and will take care of the installation and caching on the VM.
+
+  - `check-latest`: Setting this option makes the action to check for the latest available version for the version spec.
+
+  - `cache`: Quick [setup caching](#caching-packages-dependencies) for the dependencies managed through one of the predifined package managers. It can be one of "maven", "gradle" or "sbt".
+
+  #### Maven options
+  The action has a bunch of inputs to generate maven's [settings.xml](https://maven.apache.org/settings.html) on the fly and pass the values to Apache Maven GPG Plugin as well as Apache Maven Toolchains. See [advanced usage](docs/advanced-usage.md) for more.
+
+  - `overwrite-settings`: By default action overwrites the settings.xml. In order to skip generation of file if it exists set this to `false`.
+
+  - `server-id`: ID of the distributionManagement repository in the pom.xml file. Default is `github`.
+
+  - `server-username`: Environment variable name for the username for authentication to the Apache Maven repository. Default is GITHUB_ACTOR.
+
+  - `server-password`: Environment variable name for password or token for authentication to the Apache Maven repository. Default is GITHUB_TOKEN.
+
+  - `settings-path`: Maven related setting to point to the directory where the settings.xml file will be written. Default is ~/.m2.
+
+  - `gpg-private-key`: GPG private key to import. Default is empty string.
+
+  - `gpg-passphrase`: description: Environment variable name for the GPG private key passphrase. Default is GPG_PASSPHRASE.
+
+  - `mvn-toolchain-id`: Name of Maven Toolchain ID if the default name of `${distribution}_${java-version}` is not wanted.
+
+  - `mvn-toolchain-vendor`: Name of Maven Toolchain Vendor if the default name of `${distribution}` is not wanted.

 ### Caching packages dependencies
 The action has a built-in functionality for caching and restoring dependencies. It uses [actions/cache](https://github.com/actions/cache) under hood for caching dependencies but requires less configuration settings. Supported package managers are gradle, maven and sbt. The format of the used cache key is `setup-java-${{ platform }}-${{ packageManager }}-${{ fileHash }}`, where the hash is based on the following files:
-- gradle: `**/*.gradle*`, `**/gradle-wrapper.properties`
+- gradle: `**/*.gradle*`, `**/gradle-wrapper.properties`, `buildSrc/**/Versions.kt`, `buildSrc/**/Dependencies.kt`, and `gradle/*.versions.toml`
 - maven: `**/pom.xml`
 - sbt: all sbt build definition files `**/*.sbt`, `**/project/build.properties`, `**/project/**.{scala,sbt}`

 ### Check latest
+
 In the basic examples above, the `check-latest` flag defaults to `false`. When set to `false`, the action tries to first resolve a version of Java from the local tool cache on the runner. If unable to find a specific version in the cache, the action will download a version of Java. Use the default or set `check-latest` to `false` if you prefer a faster more consistent setup experience that prioritizes trying to use the cached versions at the expense of newer versions sometimes being available for download.
 
 If `check-latest` is set to `true`, the action first checks if the cached version is the latest one. If the locally cached version is not the most up-to-date, the latest version of Java will be downloaded. Set `check-latest` to `true` if you want the most up-to-date version of Java to always be used. Setting `check-latest` to `true` has performance implications as downloading versions of Java is slower than using cached versions.
 
-For Java distributions that are not cached on Hosted images, `check-latest` always behaves as `true` and downloads Java on-flight. Check out [Hosted Tool Cache](docs/advanced-usage.md#Hosted-Tool-Cache) for more details about pre-cached Java versions.

+### Using Maven Toolchains
+In the example above multiple JDKs are installed for the same job. The result after the last JDK is installed is a Maven Toolchains declaration containing references to all three JDKs. The values for `id`, `version`, and `vendor` of the individual Toolchain entries are the given input values for `distribution` and `java-version` (`vendor` being the combination of `${distribution}_${java-version}`) by default.

+### Using Microsoft distribution on GHES
+
+`setup-java` comes pre-installed on the appliance with GHES if Actions is enabled. When dynamically downloading the Microsoft Build of OpenJDK distribution, `setup-java` makes a request to `actions/setup-java` to get available versions on github.com (outside of the appliance). These calls to `actions/setup-java` 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...`.
+
+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:
+
+```yaml
+uses: actions/setup-java@v3
+with:
+  token: ${{ secrets.GH_DOTCOM_TOKEN }}
+  distribution: 'microsoft'
+  java-version: '11'
+```
+
+If the runner is not able to access github.com, any Java 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@3.2/admin/github-actions/managing-access-to-actions-from-githubcom/setting-up-the-tool-cache-on-self-hosted-runners-without-internet-access)" for more information.

 ## Hosted Tool Cache
 GitHub Hosted Runners have a tool cache that comes with some Java versions pre-installed. This tool cache helps speed up runs and tool setup by not requiring any new downloads. There is an environment variable called `RUNNER_TOOL_CACHE` on each runner that describes the location of this tools cache and this is where you can find the pre-installed versions of Java. `setup-java` works by taking a specific version of Java in this tool cache and adding it to PATH if the version, architecture and distribution match.
 
-Currently, LTS versions of Adopt OpenJDK (`adopt`) are cached on the GitHub Hosted Runners.
+Currently, LTS versions of Eclipse Temurin (`temurin`) are cached on the GitHub Hosted Runners.
 
 The tools cache gets updated on a weekly basis. For information regarding locally cached versions of Java on GitHub hosted runners, check out [GitHub Actions Virtual Environments](https://github.com/actions/virtual-environments).
+
+## Modifying Maven Toolchains
+The `setup-java` action generates a basic [Maven Toolchains declaration](https://maven.apache.org/guides/mini/guide-using-toolchains.html) for specified Java versions by either creating a minimal toolchains file or extending an existing declaration with the additional JDKs.
+
+### Installing Multiple JDKs With Toolchains
+Subsequent calls to `setup-java` with distinct distribution and version parameters will continue to extend the toolchains declaration and make all specified Java versions available.
+
+```yaml
+steps:
+- uses: actions/setup-java@v3
+  with:
+    distribution: '<distribution>'
+    java-version: |
+      8
+      11
+
+- uses: actions/setup-java@v3
+  with:
+    distribution: '<distribution>'
+    java-version: 15
+```
+
+The result is a Toolchain with entries for JDKs 8, 11 and 15. You can even combine this with custom JDKs of arbitrary versions:
+
+```yaml
+- run: |
+    download_url="https://example.com/java/jdk/6u45-b06/jdk-6u45-linux-x64.tar.gz"
+    wget -O $RUNNER_TEMP/java_package.tar.gz $download_url
+- uses: actions/setup-java@v3
+  with:
+    distribution: 'jdkfile'
+    jdkFile: ${{ runner.temp }}/java_package.tar.gz
+    java-version: '1.6'
+    architecture: x64
+```
+
+This will generate a Toolchains entry with the following values: `version: 1.6`, `vendor: jkdfile`, `id: Oracle_1.6`.
+
+### Modifying The Toolchain Vendor For JDKs
+Each JDK provider will receive a default `vendor` using the `distribution` input value but this can be overridden with the `mvn-toolchain-vendor` parameter as follows.
+
+```yaml
+- run: |
+    download_url="https://example.com/java/jdk/6u45-b06/jdk-6u45-linux-x64.tar.gz"
+    wget -O $RUNNER_TEMP/java_package.tar.gz $download_url
+- uses: actions/setup-java@v3
+  with:
+    distribution: 'jdkfile'
+    jdkFile: ${{ runner.temp }}/java_package.tar.gz
+    java-version: '1.6'
+    architecture: x64
+    mvn-toolchain-vendor: 'Oracle'
+```
+
+This will generate a Toolchains entry with the following values: `version: 1.6`, `vendor: Oracle`, `id: Oracle_1.6`.
+
+In case you install multiple versions of Java at once with multi-line `java-version` input setting the `mvn-toolchain-vendor` still only accepts one value and will use this value for installed JDKs as expected when installing multiple versions of the same `distribution`.
+
+```yaml
+steps:
+- uses: actions/setup-java@v3
+  with:
+    distribution: '<distribution>'
+    java-version: |
+      8
+      11
+    mvn-toolchain-vendor: Eclipse Temurin
+```
+
+### Modifying The Toolchain ID For JDKs
+Each JDK provider will receive a default `id` based on the combination of `distribution` and `java-version` in the format of `distribution_java-version` (e.g. `temurin_11`) but this can be overridden with the `mvn-toolchain-id` parameter as follows.
+
+```yaml
+steps:
+- uses: actions/checkout@v3
+- uses: actions/setup-java@v3
+  with:
+    distribution: 'temurin'
+    java-version: '11'
+    mvn-toolchain-id: 'some_other_id'
+- run: java -cp java HelloWorldApp
+```
+
+In case you install multiple versions of Java at once you can use the same syntax as used in `java-versions`. Please note that you have to declare an ID for all Java versions that will be installed or the `mvn-toolchain-id` instruction will be skipped wholesale due to mapping ambiguities.
+
+```yaml
+steps:
+- uses: actions/setup-java@v3
+  with:
+    distribution: '<distribution>'
+    java-version: |
+      8
+      11
+    mvn-toolchain-id: |
+      something_else
+      something_other
+```
+
+## Java-version file
+If the `java-version-file` input is specified, the action will try to extract the version from the file and install it.
+Action is able to recognize all variants of the version description according to [jenv](https://github.com/jenv/jenv). 
+Valid entry options:
+```
+major versions: 8, 11, 16, 17
+more specific versions: 1.8.0.2, 17.0, 11.0, 11.0.4, 8.0.232, 8.0.282+8
+early access (EA) versions: 15-ea, 15.0.0-ea, 15.0.0-ea.2, 15.0.0+2-ea
+versions with specified distribution: openjdk64-11.0.2
+```
+If the file contains multiple versions, only the first one will be recognized.

+# Contributors
+
+Thank you for contributing!
+
+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!
+
+## How can I contribute...

+
+* [Provide Support on Issues:pencil:](#provide-support-on-issues)

+
+## Contribute documentation
+
+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. 
+
+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!
+
+**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 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
+
+**Once you've filed the pull request:**
+
+- 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 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` prefix, for instance, [e2e-cache.yml](https://github.com/actions/setup-java/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
+- 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:
+
+## 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-java/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-java/blob/main/CODE_OF_CONDUCT.md#our-standards), refer to the [enforcement](https://github.com/actions/setup-java/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 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-java/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
