 # sccache-setup-action
+
 A github action to install and setup sccache to speed up your builds
+
+It installs (on Windows using `choco` and on MacOS using `brew`), recover a cached sccache cache using the github cache action
+then setup and run a sccache server.
+
+On Linux, it assumes sccache is available.
+
+Example usage:
+
+```
+  - name: Install and setup sccache
+    uses: f3d-app/sccache-setup-action@v1
+    with:
+      key: MyKey-0
+```
+
+Then during the configuration of your build, add sccache as a launcher, eg, for CMake:
+
+```
+  - name: Configure
+    working-directory: ${{github.workspace}}/build
+    shell: bash
+    run: >
+      cmake ../source
+      -DCMAKE_CXX_COMPILER_LAUNCHER=sccache
+      -DCMAKE_C_COMPILER_LAUNCHER=sccache
+```
+
+Resulting caches can be seen in your actions tab.
+
+To check the sccache action is behaving as expected, it is possible to add the following at the end of your job:
+
+```
+  - name: Stop and check sccache
+    shell: bash
+    run: sccache --show-stats
+```
+
+Please note sccache does not work with Visual Studio Generator on Windows but requires ninja-build in that case:
