 ## 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.
+[GCC](https://en.wikipedia.org/wiki/GNU_Compiler_Collection) is recommended as the compiler installed for `Pallet` projects.
 
-This tool calls `gcc` internally, so without it, it would fail.
+You can define a different `gcc` compatible compiler instead per-project by editing `Pallet.toml`:
 
-At some point I would like to update `Pallet.toml` to instead allow more configuring of how the build should be performed.
+```toml
+name = "my-app"
+default_build = "debug"
+compiler = "clang"
+
+[[build]]
+name = "debug"
+args = [
+    "-g",
+    "-O0",
+]
+
+[[build]]
+name = "release"
+args = [
+    "-DNDEBUG",
+    "-O3",
+]
