+### Incremental build cache
+
+To further speed up consequent builds, you may want to cache the incremental build cache directory.

+Example:
+
+```yaml
+- uses: actions/cache@v3
+  with:
+    path: ~/work/_temp/_github_home/.cache/unity3d/bee
+    key: IncrementalBuildCache-MyProjectName-TargetPlatform

+On a Windows runner (e.g. if building for IL2CPP) this path is different, but the incremental build
+cache is automatically saved with the Library folder.

 In order to make builds run faster, you can cache Library files from previous builds. To do so
 simply add Github Actions official [cache action](https://github.com/marketplace/actions/cache)
 before any unity steps.
