+### Structure
+
+It is preferred that you read the scripts yourself, as my understanding (and presentation) may be basic.
+
+* `awais.instagrabber`
+  * `activities`: Scripts directly binding to each view. Assigns `adapters`.
+  * `adapters`: Scripts used to present a list of `models` from `asyncs` into `activities`.
+    * Those inside `viewholder` are for frontend, while others are for backend.
+  * `asyncs`: Scripts used to communicate with Instagram. Returns `models` which is sent to `adapters`.
+    * `asyncs.i`: Scripts that fetch data from `i.instagram.com`, except DM.
+    * `asyncs.direct_messages`: As the name suggests, communication scripts used for DM.
+  * `customviews`: Custom frontend components for this app.
+  * `dialogs`: Scripts directly binding to dialogs (i.e. those that are nested in the main view).
+  * `fragments.directmessages`: Scripts directly binding to each fragment ("small views") within `DirectMessageActivity` in `activities`.
+  * `interfaces`: Custom backend components for this app.
+  * `models`: Data structure for Instagram API responses from `asyncs`.
+  * `utils`: Various tools.
+  * `MainHelper.java` is basically an extension of `activities.main`.
+* `awaisomereport`: Crash reporter. Shouldn not require too much maintenance.
+* `thoughtbot.expandableadapter`: These are for the follower comparison view, which allows grouping users.

 ### I can't code Java, but I want to!
 
 Fun fact: Austin took over this project and learned Java on the fly (I'm not joking, I only do JavaScript before taking this over).
