    From the README

    Boringtun is currently undergoing a restructuring. You should probably not rely on or link to the master branch right now. Instead you should use the crates.io page.

    BoringTun is an implementation of the WireGuard® protocol designed for portability and speed.

    BoringTun is successfully deployed on millions of iOS and Android consumer devices as well as thousands of Cloudflare Linux servers.

    By default the executable is placed in the ./target/release folder. You can copy it to a desired location manually, or install it using cargo install --bin boringtun --path ..
