 ## Usage
-Inputs `java-version` and `distribution` are mandatory. See [Supported distributions](#supported-distributions) section for a list of available options.
 
-### Basic
+  - `java-version`: _(required)_ The Java version to set up. Takes a whole or [semver](#supported-version-syntax) Java version.
-**Eclipse Temurin**
+   
+  - `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: `x64`.
+
+  - `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 diractory 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:

 ### 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.

 Currently, LTS versions of Adopt OpenJDK (`adopt`) 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
+```
