@@ -97,3 +97,110 @@ If you want your project to target Essence, you need to generate the API header
 Currently supported languages are 'c' (also works for C++), 'zig' and 'odin'.
 
 There is currently no documentation for the API; for examples of how to use the API, consult the standard applications in the `apps/` folder of the source tree. Minimal sample applications are placed in the `apps/samples` folder. By placing your application's `.ini` file in the `apps/` folder, it will be automatically built by the build system.
