 ## Features
-
 You can view a more comprehensive list of features [here](https://github.com/redstrate/prism/wiki/List-of-Features).
 
 ## Building
 There are instructions for Windows, Linux, and macOS targets in the [wiki](https://github.com/redstrate/prism/wiki).
 
 There is an example app provided in `example/`. If you want to build the tooling or the example, use the CMake options `BUILD_EXAMPLE` and `BUILD_TOOLS` respectively.

+The ideal way to use it is by letting prism take over your main() and implementing an app_main() instead,
+(and using `add_platform_executable` in CMake) but I'm working on letting developers use the engine as a regular library too.
