+- Downloaded packages are stored in `%LOCALAPPDATA%\STARTLINER\data\pkg` (or `$XDG_DATA_HOME/startliner/pkg`).
+- Each profile is associated with a prefix directory `%LOCALAPPDATA%\STARTLINER\data\profile-{game}-{name}` which includes:
+    - `option` with junctions of vanilla opts as well as Rainycolor package opts
+    - `BepInEx` with Rainycolor mods copied over
+        - It's currently pointless to symlink those since they are measured in kilobytes
+    - `segatools.ini` generated on-the-fly and pointing at `option`
+        - It's currently based on the existing `segatools.ini` but that will change in the future
+    - logs
+- Persistent configuration is stored in `%APPDATA%\STARTLINER` (or `$XDG_CONFIG_HOME/startliner`).
