+## Translate-c
+
+If you want to test translating C code to Zig use `translate-c`:
+
+```c
+// translate-c
+// c_frontend=aro,clang
+// target=x86_64-linux
+//
+// pub const foo = 1;
+// pub const immediately_after_foo = 2;
+//
+// pub const somewhere_else_in_the_file = 3:
+```
+
+## Run Translated C
+
+If you want to test translating C code to Zig and then executing it use `run-translated-c`:
+
+```c
+// run-translated-c
+// c_frontend=aro,clang
+// target=x86_64-linux
+//
+// Hello world!
+```

 ## Incremental Compilation
 
 Make multiple files that have ".", and then an integer, before the ".zig"
