	By its nature LFS is a very programmer friendly game and, while customisation of the game engine itself is frowned upon, there are many other avenues available for budding addon writers to explore. Whether it's parsing some esoteric file format, writing your own server system, or just grabbing your friend's hotlaps from LFSWorld, LFS has something to keep even the most adventurous hackers busy!

 The following category attempts to explain and document the many various programmer topics related to LFS, in hopefully a clear and useful way. Our job of course is not to teach you how to program, there are many, many books about that, but to show you the myriad possibilities for customising LFS which are right at your fingertips.

 [[InSim]] is a protocol which allows an external program to communicate with Live for Speed. It allows you to create a socket connection with the game and to send and receive packets of data. The InSim protocol describes how each of these packets is formatted, and any programming language which can create a network connection and send and receive strings of binary data can interface with it.

 With the release of mods in 2021, there wasn't a good way to fetch information about mods. Victor therefore introduced the REST API where users can fetch nearly anything imaginable from mods. There was a [https://www.lfs.net/forum/thread/95699 LFS Forum discussion] about this.

 The LFS game client itself is written in C++ and many of data-types referenced throughout the documentation are named in accordance with that language. The following table represents a breakdown of what each data-type means and what sort of value it holds.

+=== LFS strings and escape codes ===
 Strings in LFS are C-style strings, meaning that they end with a NULL character, or are often padded with NULL characters. Most other high-level languages have done away with this limitation, so it's important to strip any NULL characters from the end of a string before using it.
