@@ -4,6 +4,14 @@ Pallet is a project manager and build system for C inspired by Rust's Cargo.
 
 This is a toy project not meant to be taken very seriously.
 
+## Requirements for Use
+
+[GCC](https://en.wikipedia.org/wiki/GNU_Compiler_Collection) is required as it is currently the back-end tool used to compile the C code.
+
+This tool calls `gcc` internally, so without it, it would fail.
+
+At some point I would like to update `Pallet.toml` to instead allow more configuring of how the build should be performed.
+
 ## Usage
 
 - `pallet new <project>`: initializes a new project at `project`
