+Cache storage space for GitHub actions is limited, and writing new cache entries can trigger the deletion of existing entries.
 Eviction of shared cache entries can reduce cache effectiveness, slowing down your `gradle-build-action` steps.
 
 There are a number of actions you can take if your cache use is less effective due to entry eviction.

+#### Select branches that should write to the cache
 
-GitHub cache entries are not shared between builds on different branches. This means that identical cache entries will be stored separately for different branches.
-The exception to the is cache entries for the default (`master`/`main`) branch can be read by actions invoked for other branches.
+GitHub cache entries are not shared between builds on different branches. 
+This means that each PR branch will have it's own Gradle User Home cache, and will not benefit from cache entries written by other PR branches.
+An exception to this is that cache entries written in parent and upstream branches are visible to child branches, and cache entries for the default (`master`/`main`) branch can be read by actions invoked for any other branch.
 
-An easy way to reduce cache usage when you run builds on many different branches is to only permit your default branch to write to the cache,
-with all other branch builds using `cache-read-only`. See [Using the caches read-only](#using-the-caches-read-only) for more details.
+By default, the `gradle-build-action` will only _write_ to the cache for builds run on the default (`master`/`main`) branch. 
+Jobs run on other branches will only read from the cache. In most cases, this is the desired behaviour, 
+because Jobs run against other branches will benefit from the cache Gradle User Home from `main`, 
+without writing private cache entries that could lead to evicting shared entries.
+
+If you have other long-lived development branches that would benefit from writing to the cache, 
+you can configure these by overriding the `cache-read-only` action parameter. 
+See [Using the caches read-only](#using-the-caches-read-only) for more details.
 
 Similarly, you could use `cache-read-only` for certain jobs in the workflow, and instead have these jobs reuse the cache content from upstream jobs.

+
+You can use the `gradle-build-action` on GitHub Enterprise Server, and benefit from the improved integration with Gradle. Depending on the version of GHES you are running, certain features may be limited:
+- Build scan links are captured and displayed in the GitHub Actions UI
+- Easily run your build with different versions of Gradle
+- Save/restore of Gradle User Home (requires GHES v3.5+ : GitHub Actions cache was introduced in GHES 3.5)
+- Support for GitHub Actions Job Summary is not yet available in any version of GHES. Instead of producing a Job Summary, the build-results summary and caching report will be written to the workflow log, as part of the post-action step.

+#   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

+#   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.
