 ## Build System
 
-You will need to re-run `./configure` whenever `splat.yaml` or the number of source files changes (e.g. a function is matched and its `.s` file is removed). If you `git pull` and `ninja` breaks, you probably need to re-run `./configure`.
+You will need to edit `splat.yaml` and re-run `./configure` in certain circumstances, among which are the changing of source file names, the creation or deletion of source files, and migrating data from a .data.s file into c. If you `git pull` and `ninja` breaks, you probably need to re-run `./configure`.
 
 If you use Visual Studio Code, you can use _Run Build Task_ (Ctrl+Shift+B) to run `ninja`. Any errors or warnings generated by the compiler will show up in the _Problems_ tab.
