+- `emit` is responsible for looking at all the parsed and filtered content and then appropriately creating files and returning a list of paths to files the plugin created.
+- `partialEmit` is an optional function that enables incremental builds. It receives information about which files have changed (`changeEvents`) and can selectively rebuild only the necessary files. This is useful for optimizing build times in development mode. If `partialEmit` is undefined, it will default to the `emit` function.
+- `getQuartzComponents` declares which Quartz components the emitter uses to construct its pages.
 
 Creating new files can be done via regular Node [fs module](https://nodejs.org/api/fs.html) (i.e. `fs.cp` or `fs.writeFile`) or via the `write` function in `quartz/plugins/emitters/helpers.ts` if you are creating files that contain text. `write` has the following signature:
