+## FAQ
+
+### What about support for F1 2021-2018?
+
+My initial goal was to provide support from the most recent game all the way to F1 2018, starting development with implementing support for the latter and _working my way up_. I ended up limiting my crate's backwards compatibility to F1 22, because:
+- When I was done with the 2021 format, certain structs had so many fields that got added, removed, or in some cases even reordered with each new format that they became a nightmare to manage and navigate through in the documentation.
+- I realised that most users would probably never end up using formats that are over 2-3 years old anyway. Limiting support to the 3 most recent packet formats also happens to be the actual policy in the latest games.
+
+However, if you believe there's a method in the madness and/or need support for these older packet formats, feel free to open an issue or a pull request.
+
+### Are there any alternatives to this crate?
+
+If you're looking for a crate that supports an older telemetry format or need a built-in UDP client, consider one of the following:
+
++ [f1_game_telemetry](https://crates.io/crates/f1_game_telemetry) - supports the 2022 format and offers a built-in UDP client
++ [f1-telemetry-client](https://crates.io/crates/f1-telemetry-client) - supports the 2020 format and offers a built-in UDP client
