-## Caching
+# Build scans
 
-This action provides 3 levels of caching to help speed up your GitHub Actions:
-
-- `distributions` caches any distributions downloaded to satisfy a `gradle-version` parameter ;
-- `gradle-user-home` caches downloaded dependencies, wrapper distributions, and other stuff from the Gradle User home directory ;
-- `project-dot-gradle` caches stored [configuration-cache](https://docs.gradle.org/nightly/userguide/configuration_cache.html) state, saving time configuring the build.
-
-Each of these are enabled by default. To save caching space, you can disable any of them as follows:
-
-```yaml
-distributions-cache-enabled: true
-gradle-user-home-cache-enabled: true
-project-dot-gradle-cache-enabled: true
-```
-
-The distributions cache uses a cache key that is unique to the downloaded distribution. This will not change over time.
-
-The `gradle-user-home` and `project-dot-gradle` caches compute a cache key based on the current commit and the Gradle invocation.
-As such, these are likely to change on each subsequent run of GitHub actions, allowing the most recent state to always be available in the GitHub actions cache.
-
-By default, this action aims to cache any and all reusable state that may be speed up a subsequent build invocation. 
-
-At this time it is not possible to fine-tune this caching. If you have a legitimate use case for fine-grained caching or restricting which files are cached, please raise an issue.
-
-### Using the caches read-only
-
-Cache storage space is limited for GitHub actions, and writing new cache entries can trigger the deletion of exising entries.
-In some circumstances, it makes sense for a Gradle invocation to read any existing cache entries but not to write changes back.
-For example, you may want to write cache entries for builds on your `main` branch, but not for any PR build invocations.
-
-You can enable read-only caching for any of the caches asfollows:
-
-```yaml
-distributions-cache-enabled: read-only
-gradle-user-home-cache-enabled: read-only
-project-dot-gradle-cache-enabled: read-only
-```
-
-## Build scans
-
-If your build publishes a [build scan](https://gradle.com/build-scans/) the `gradle-build-action` action will emit the link to the published build scan as an output named `build-scan-url`.
+If your build publishes a [build scan](https://gradle.com/build-scans/) the `gradle-command-action` action will emit the link to the published build scan as an output named `build-scan-url`.
 
 You can then use that link in subsequent actions of your workflow.

-#
-#   Gradle start up script for POSIX generated by Gradle.
-#
-#   Important for running:
-#
-#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
-#       noncompliant, but you have some other compliant shell such as ksh or
-#       bash, then to run this script, type that shell name before the whole
-#       command line, like:
-#
-#           ksh Gradle
-#
-#       Busybox and similar reduced shells will NOT work, because this script
-#       requires all of these POSIX shell features:
-#         * functions;
-#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
-#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
-#         * compound commands having a testable exit status, especially «case»;
-#         * various built-in commands including «command», «set», and «ulimit».
-#
-#   Important for patching:
-#
-#   (2) This script targets any POSIX shell, so it avoids extensions provided
-#       by Bash, Ksh, etc; in particular arrays are avoided.
-#
-#       The "traditional" practice of packing multiple parameters into a
-#       space-separated string is a well documented source of bugs and security
-#       problems, so this is (mostly) avoided, by progressively accumulating
-#       options in "$@", and eventually passing that to Java.
-#
-#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
-#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
-#       see the in-line comments for details.
-#
-#       There are tweaks for specific operating systems such as AIX, CygWin,
-#       Darwin, MinGW, and NonStop.
-#
-#   (3) This script is generated from the Groovy template
-#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
-#       within the Gradle project.
