+# Snail
+
+I've been using snail as my only terminal for over a year, but I would not recommend other people use it as part of their critical infrastructure yet. The apis might change before the 1.0 release and I can't garuantee it won't eat your data. That being said, I welcome feedback from the brave!
+
+## Install and run from source
+Install dependencies
+```sh
+npm install
+```
+Running snail
+```sh
+npm start
