+### Set Up Ccache
+
+To speed up repeated compilations, we recommend that you install
+[ccache](https://ccache.dev), a tool that wraps your compiler so that it can
+cache build objects locally.
+
+#### Linux
+
+You can install it using the package manager, e.g. `sudo apt install ccache`
+(Ubuntu) or `sudo dnf install ccache` (RHEL).
+
+#### macOS
+
+You can install it using Homebrew, i.e. `brew install ccache`.
+
+#### Windows
+
+You can install it using Chocolatey, i.e. `choco install ccache`. If you already
+have Ccache installed, then `choco upgrade ccache` will update it to the latest
+version. However, if you see an error such as:
+
+```
+terminate called after throwing an instance of 'std::bad_alloc'
+      what():  std::bad_alloc
+C:\Program Files\Microsoft Visual Studio\2022\Community\MSBuild\Microsoft\VC\v170\Microsoft.CppCommon.targets(617,5): error MSB6006: "cl.exe" exited with code 3.
+```
+
+then please install a specific version of Ccache that we know works, via: `choco
+install ccache --version 4.11.3 --allow-downgrade`.
