 Installing on your board
-========
+========================
+
+Installing on Ubuntu
+--------------------
+
+Here is a PPA for installing on ubuntu:
+https://launchpad.net/~mraa/+archive/ubuntu/mraa
+
+```bash
+sudo add-apt-repository ppa:mraa/mraa
+sudo apt-get update
+sudo apt-get install libmraa1 libmraa-dev mraa-tools python-mraa python3-mraa
+```
+
+Node.js package is available seperately.
+
+Install on Arch Linux
+---------------------
+
+There is an AUR package for mraa here: https://aur.archlinux.org/packages/mraa
+
+Installing for Node.js only
+---------------------------
+
+You can also install just the node.js mraa module by using npm. You will need a
+C++ compiler and the node development headers, however it's not required to
+have SWIG installed.
+
+```bash
+npm install mraa
+```
+
+Note that installing mraa in this way builds mraa without json-c so you cannot
+use mraa_init_json_platform(). Also building this way means the mraa.node
+includes a static version of libmraa rather than relying on a dynamic library
+in /usr/lib.
+
+Installing on Intel 32bit Yocto based opkg image
+------------------------------------------------
 
 See the section below on compiling or use our repository to install on a glibc
 based yocto poky image that supports opkg. Adding this repository is as simple
 as and you'll have the latest stable tagged build of mraa installed!

 ## Running Imraa

 Before being able to use mraa to program the Arduino101 you will need to run
 imraa to flash the sketch file onto the board. The sketch file that imraa will
 look for is located here: [Arduino101 Sketch](http://iotdk.intel.com/misc/ConfigurableFirmataCurieImu.ino.bin).

+JSON platform {#jsonplat}
+=============
+
+JSON platform loading allows libmraa users who work with **simple** and unsupported
+boards to create JSON configuration files which libmraa understands, allowing
+libmraa to just 'work' with the unsupported platform. JSON platform **does not work**
+with boards which require advanced functions which overwrite default functionality or
+boards that require the mux functionality.
+
+Syntax
+------
+
+The JSON file that libmraa reads needs specific values to be set by default, they
+are required in every JSON file intended to be used to load the platform.
+The keywords are case sensitive so be aware when writing the JSON file.
+Each heading is a top level key in the JSON file, each key's type is Array

+
+**THIS INDEX'S THE PIN ARRAY**
+Each available pin specified using pin_count requires a label. There is no need to use an
+index identifier as the json objects are indexed as they are read, starting with the first
+json object being treated as index 0.
+
+The number of json objects in layout should be equal to the pin_count.
