+## Minimum supported Rust version (MSRV)
+
+Both `ffmpeg-the-third` and `ffmpeg-sys-the-third` currently require a Rust version of 1.61.0 or higher. Increases in MSRV will result in a semver MINOR version increase.
+
+If you are having issues compiling this crate on your version of Rust, there are two tools you can use to help find MSRV-compatible dependency versions:
+
+- Install a nightly Rust toolchain and run `cargo +nightly update -Zmsrv-policy`. This will automatically resolve dependencies to versions that are compatible with the `rust-version` in `Cargo.toml`.
+- Check the `Cargo.lock.MSRV` in this repository. It contains dependency versions that are known to compile on the MSRV. In the simplest case, you can just `cp Cargo.lock.MSRV Cargo.lock`. For more complex dependency graphs, you might need to manually select compatible versions from the `Cargo.lock.MSRV`.
