+# Development Guide
+
+## Getting started
+
+The easiest way is to get the source of the `language-idris` package via the `apm`-tooling:
+
+```bash
+apm dev language-idris
+```
+
+This will install the package in the folder `~/github/language-idris`. You will then be able to use the development version of `language-idris` by invoking atom from any directory containing some idris files using
+
+```bash
+atom -d .
+```
+
+## Development process
+
+Atom is basically a browser and when doing development it can be useful to open the dev console.
+
+<kbd>Alt</kbd>+<kbd>Cmd</kbd><kbd>i</kbd> opens the developer console on Mac OS X. This enables you to see console logging output and exceptions.
+
+You can edit the sourcecode in another atom window:
+
+```
+$~/github/language-idris> atom .
+```
+
+Anytime you want to restart your project with the latest changes, you can just reload the window using `Window: Reload`.
+
+## Code Structure

+    └── repl-view.coffee
+```
+
+The best point to get started is to dig into `idris-controller.coffee`. Almost all defined commands talk to a spawned idris process using the [Idris IDE protocol](http://docs.idris-lang.org/en/latest/reference/ide-protocol.html). This protocol communicates with Idris via S-Exp Expressions. If you want to see this communication have a look at `utils/Logger.coffee`.
+
+In order to send a command to idris, you will probably need some information from the current editor context. There are plenty of examples in the code and a helper package in the `utils` section. Once you have a reply you will probably need to format it. This can be done via one of the `highlighters`. Again, this is something which occurs again and again in the code.
+
+
+## Specs
+
+There are (too) few tests defined in the spec directory. You can execute them using `Window: Run package specs`.

 ## Development
 
-To work on this plugin you need to clone it into your atom directory
-and rename the folder to `language-idris` or the package settings won't get picked up.
-Then you need an `apm install` from the `language-idris` folder to install the dependencies.
-
-Or you can execute `apm dev language-idris`. This will install the package in a separate directory and you need to start
-Atom in dev-mode to load the development packages (`atom -d your/folder`).
