+### Use prebuilt binary
+
+To furter speed up the CI pipeline the action [taiki-e/install-action](https://github.com/marketplace/actions/install-development-tools) can be used. This will save time by using a prebuilt binary from cargo-audit's [release](https://github.com/rustsec/rustsec/releases) page instead of installing it from source each time this action is triggered.
