-Welcome to the Abacus project website.
+## So... what IS Abacus?
-This website is currently under construction, please, check
+It's a calculator. Obviously. But what makes it better than
-back later.
+what already exists? There's a few things. Abacus is:
+* Programmable, and not in TI Basic.
+* Precise. With the "precise" option, Abacus can keep up to 50 significant figures.
+* Capable. Ever wonder what 2<sup>700</sup> is? How about 8!!? Abacus can tell you!
+* Offline. While Wolfram Alpha can do powerful math, it needs internet connection!
+* Built for the desktop. Why use buttons on the screen when there's buttons on the keyboard?
+* Open source. Don't like something? Help is always welcome!
+
+## Why was Abacus made?
+The initial project was proposed for the [Northwest Advanced Programming Workshop](http://nwapw.org/about/).
+You can read the project proposal on the main GitHub page, although the idea has
+changed quite a bit, mostly in shifting from "fast" to "precise".
+
+## What is Abacus made with?
+Java and Kotlin. Java provides a good layer of abstraction and a great standard
+library, while Kotlin allows for the reduction of boilerplate code and null
+safety. Using JVM-based languages also allows Abacus to expose its entire
+API to plugins, and load them at runtime.
