-# Setup
+# Installation
 
-Fork the repository, clone it then:
+1. `npm install`
 
-1. `cd TheaterJS`
-2. `npm install`
+## Scripts
 
-# Tasks
+- `lint`: lint the files.
+- `test`: run the tests.
+- `build`: transpile the files to ES5.
 
-TheaterJS' build workflow is based on npm scripts and webpack:
-
-* `npm run build` - build the dist version of TheaterJS.
-* `npm run dev` - watch for changes and build the dist version when needed.
-* `npm run lint` - lint js files using [standard](http://standardjs.com/).
-* `npm run test` - run the tests.
-
-Note: there's a git pre-commit hook that's going to run the tests when using `git commit`.

-# Adding a keyboard
+## Adding a keyboard
 
 The keyboards are implemented in `src/keyboards.json`.
 A mapped keyboard is just a list of characters, ordered after their "physical" equivalent.
 So for example, the english keyboard (aka `qwerty`) looks like this:
 
 ```javascript
-[
-  "qwertyuiop",
-  "asdfghjkl",
-  "zxcvbnm"
-]
+["qwertyuiop", "asdfghjkl", "zxcvbnm"];
 ```
