+# AwwKoala
+## A Websocket Wiki and Kind Of A List Application
+![Version 1.0](https://img.shields.io/badge/version-1.0-brightgreen.svg)
+
+This is a self-contained wiki webserver that makes sharing easy and _fast_. You can make any page you want, and any page is editable by anyone. Pages load instantly for editing, and have special rendering for whether you want to view as a web page or view as list.
+
+# Features
+## Just type.
+To jot a note, simply load the page at [`/`](http://AwwKoala.com/) and just start typing. No need to press edit, the browser will already be focused on the text. No need to press save - it will automatically save when you stop writing. The URL at [`/`](http://AwwKoala.com/) will redirect to an easy-to-remember name that you can use to reload the page at anytime, anywhere. But, you can also use any URL you want, e.g. [`/AnythingYouWant`](http://AwwKoala.com/AnythingYouWant).
+
+## Views
+All pages can be rendered into HTML by adding `/view`. For example, the page [`/AnythingYouWant`](http://AwwKoala.com/AnythingYouWant) is rendered at [`/AnythingYouWant/view`](http://AwwKoala.com/AnythingYouWant/view). You can write in HTML or [Markdown](https://daringfireball.net/projects/markdown/) for page rendering. Math is supported with [Katex](https://github.com/Khan/KaTeX) using `$\frac{1}{2}$` for inline equations and `$$\frac{1}{2}$$` for regular equations.
+
+## Lists
+If you are writing a list and you want to tick off things really easily, just add `/list`. For example, after editing [`/grocery`](http://AwwKoala.com/grocery), goto [`/grocery/list`](http://AwwKoala.com/grocery/list). In this page, whatever you click on will be striked through and moved to the end. This is helpful if you write a grocery list and then want to easily delete things from it.
+
+## Automatic versioning
+All previous versions of all notes are stored and can be accessed by adding `?version=X` onto `/view` or `/edit`. If you are on the `/view` or `/edit` pages the menu below will show the most substantial changes in the history. Note, only the _current_ version can be edited (no branching allowed, yet).
