-### 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'

-```
-
-then please install a specific version of Ccache that we know works, via: `choco
-install ccache --version 4.11.3 --allow-downgrade`.
