 # HotPocket by BTHLabs
 
-This repository contains the _HotPocket_ project.
+Minimal self-hosted bookmarking app :).
+
+## The what, the why and the ugly
+
+HotPocket is a minimal self-hosted bookmarking app. It combines a Web
+application, companion apps, browser extensions to give you a way to quickly
+save links for later.
+
+HotPocket came to be to fill in the blank left by Pocket, after Mozilla shut it
+down. I looked at the existing alternatives and found them either too
+feature-rich, too involved to self-host or otherwise not to my liking. So I
+decided to sit down and build something for myself.
+
+With the what and why out of the way, let's talk about the ugly... At its core
+HotPocket is a personal project. I built it by myself and for myself. It may
+or may not fit your needs. If it does, happy saving!
+
+If you're feeling up for an adventure, continue reading below :).
