 ## Design
 
 - `extension/`: Browser extension, written in JS
+  - [`background.js`](extension/background.js): **The most interesting file**. Defines all the
+    synthetic files and what browser operations they map to.
 - `fs/`: Native FUSE filesystem, written in C
-  - `tabfs.c`: Talks to FUSE, implements fs operations, talks to browser.
+  - [`tabfs.c`](fs/tabfs.c): Talks to FUSE, implements fs operations, talks to extension.
 
 When you, say, `cat` a file in the tab filesystem:
