+### How to merge a Dependabot PR
+
+The "distribution" for a GitHub Action is checked into the repository itself. 
+In the case of the `gradle-build-action`, the transpiled sources are committed to the `dist` directory. 
+Any production dependencies are inlined into the distribution. 
+So if a Dependabot PR updates a production dependency (or a dev dependency that changes the distribution, like the Typescript compiler), 
+then a manual step is required to rebuild the dist and commit.
+
+The simplest process to follow is:
+1. Checkout the dependabot branch locally eg: `git checkout dependabot/npm_and_yarn/actions/github-5.1.0`
+2. Run `npm install` to download and the new dependencies and install locally
+3. Run `npm run build` to regenerate the distribution
+4. Push the changes to the dependabot branch
+5. If/when the checks pass, you can merge the dependabot PR

 [Cache debugging ](#cache-debugging-and-analysis) can provide insight into which cache entries are the largest,
 and you can selectively [exclude content using `gradle-home-cache-exclude`](#gradle-user-home-cache-tuning).
 
+#### Removing unused files from Gradle User Home before saving to cache
+
+The Gradle User Home directory has a tendency to grow over time. When you switch to a new Gradle wrapper version or upgrade a dependency version
+the old files are not automatically and immediately removed. While this can make sense in a local environment, in a GitHub Actions environment
+it can lead to ever-larger Gradle User Home cache entries being saved and restored.
+
+In order to avoid this situation, the `gradle-build-action` supports the `gradle-home-cache-cleanup` parameter. 
+When enabled, this feature will attempt to delete any files in the Gradle User Home that were not used by Gradle during the GitHub Actions workflow, 
+prior to saving the Gradle User Home to the GitHub Actions cache.
+
+Gradle Home cache cleanup is disabled by default.  You can enable this feature for the action as follows:
+```yaml
+gradle-home-cache-cleanup: true
+```
+
 ## Saving build outputs
 
 By default, a GitHub Actions workflow using `gradle-build-action` will record the log output and any Build Scan links for your build,

+#   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.
