-Revived Version by Austin.
+## InstaGrabber
 
-Coming soon™
+InstaGrabber is an app that allows downloading Instagram posts (and, in fact, an open-source drop-in replacement for the Instagram app, but with only read functionalities).
+
+This app is originally made by [@AwaisKing](https://github.com/AwaisKing) who posted on [GitLab](https://gitlab.com/AwaisKing/instagrabber). I decided to continue the app cuz why not, ~~even though it might not be that *cash money*.~~ (Also I need to learn Java.)
+
+### Download
+
+Download [here](https://github.com/austinhuang0131/instagrabber/releases). Under each release is an `app-release.apk`. Just install that. Unfortunately,
+
+* I have to sign it with my own key, which means you have to uninstall the old app and log in again. Sorry.
+* I don't plan on getting a Google Play Dev account yet, so that means Google Play will shout at you for installing "malware". Just ignore it. If you're skeptical (which is not necessarily a bad thing), just inspect the source code and build the app yourself.
+
+### How to log in
+
+Original instructions are [here](https://gitlab.com/AwaisKing/instagrabber/-/wikis/home#how-to-login-eli5-1).
