 ## Compiler
 
+Two of the main open-source compiler projects:
+
+* GCC (Gnu Compiler Collection) Age: 31 years
+* LLVM (originally: Low-Level Virtual Machine) Age: 16 years
+
+In this course LLVM will be used to turn our source code, written in Rust,
+into ready to run ARM instructions.
+
 ## Toolchain
 
 ### Git
 
-### Cargo-binutils
+Git is a distributed revision control system, most likely most of you have heard of it, maybe even used it.
+
+It allows for convenient collaboration and handles everything from small one-file projects to massive
+[projects](https://github.com/torvalds/linux).
