 ## How to use the library in your own project
 
+Keep in mind that [nobuild.h](./nobuild.h) is an [stb-style](https://github.com/nothings/stb/blob/master/docs/stb_howto.txt) header-only library. That means that just including it does not include the implementations of the functions. You have to define `NOBUILD_IMPLEMENTATION` macro before the include. See our [nobuild.c](./nobuild.c) for an example.

 3. Bootstrap the `nobuild` executable:
    - `$ cc nobuild.c -o nobuild` on POSIX systems
    - `$ cl.exe nobuild.c` on Windows with MSVC
