-## Example Usage (with caching)
-
-```yml
-- name: Cache LLVM and Clang
-  id: cache-llvm
-  uses: actions/cache@v3
-  with:
-    path: |
-      C:/Program Files/LLVM
-      ./llvm
-    key: llvm-3.5
-- name: Install LLVM and Clang
-  uses: KyleMayes/install-llvm-action@v1
-  with:
-    version: "3.5"
-    cached: ${{ steps.cache-llvm.outputs.cache-hit }}
-```
-
-**Note:** Based on some benchmarks on a GitHub Actions Ubuntu runner, an uncached install of the LLVM and Clang binaries using this action takes about 60 seconds but a cached install takes only about 20 seconds.

 ## Linking to Installed Libraries (Linux)
 
 If your build system requires a library from the installed LLVM and Clang binaries such as `libclang.so`, and it fails to find it, then it may help to create a symlink for the versioned `.so` using the following step which utilizes the `LLVM_PATH` environment variable set by this action:
