 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 separately.
+
+Install on Arch Linux
+---------------------
+
+There is an AUR package for mraa here: https://aur.archlinux.org/packages/mraa
+
+Install on openSUSE
+-------------------
+
+```bash
+REPO="openSUSE_Tumbleweed"
+if test "$(arch)" == "aarch64"; then
+  REPO="openSUSE_Factory_ARM"
+fi
+sudo zypper ar http://download.opensuse.org/repositories/hardware/$REPO/hardware.repo
+sudo zypper in mraa
+```
+
+Installing for Node.js only
+---------------------------
+
+> Note: Node.js 7.0.0+ is not supported. You'll have to downgrade to 6.x.x.
+
+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.
+
+Subplatforms (i.e. Firmata) have to be added manually with this kind of install
+from your application, as shown in [this example](examples/javascript/firmata.js).
+
+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!

+96Boards Development Platform    {#96boards}
+=============================
+
+96Boards is a range of hardware specifications created by Linaro to make the latest ARM-based processors available to developers at a reasonable cost. The specifications are open and define a standard board layout for SoC-agnostic (processor independent)  development platforms that can be used by software application, hardware device, kernel and other system software developers. Boards produced to the 96Boards specifications are suitable for rapid prototyping, hobbyist projects or incorporation into new systems for a wide range of applications including desktop and laptop computing, the digital home, digital signage, point of sale (POS), high-end audio, robotics and drones, artificial intelligence, virtual reality, IoT and industrial control. 
+
+Standardized expansion buses for peripheral I/O have led to a wide range of compatible add-on mezzanine boards  that will work across a variety of 96Boards products. Users have access to a wide range of boards with different features at various price points. In addition, some SoC vendors have announced long term availability of the SoC to encourage their use in products with long life cycles.

+System-on-Chip (SoC) FPGA, which combines the latest dual-core Cortex-A9 embedded cores with
+industry-leading programmable logic for ultimate design flexibility. Users can now leverage the
+power of tremendous re-configurability paired with a high-performance, low-power processor system.
+Altera’s SoC integrates an ARM-based hard processor system (HPS) consisting of processor,
+peripherals and memory interfaces tied seamlessly with the FPGA fabric using a high-bandwidth
+interconnect backbone. The DE10-Nano development board is equipped with high-speed DDR3 memory,

 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).

+
+**SPI**
+
+Two SPI buses are available, with one chipselect each. Pins listed are MRAA
+numbered pins. Other chip selects are available if enabled in BIOS/EEPROM but
+cannot be enabled as BIOS options. You will need the spidev kernel module
+loaded, Ostro-XT and ref-os-iot does this by default.

+
+(remove 40 from numbers to get pin header number for pins on low speed header

+
+**UART** Some pins are labelled as UARTs but are not configured in BIOS as UART
+so only available UART is on the FTDI header. Disable the getty on ttyS2 and
+use mraa's uart raw mode to initialise on ttyS2. The Jumper J8 can be used to
+switch between using the FTDI 6 pin header and the micro USB output.

+Pin Mapping
+-----------
+
+The Intel Joule expansion board has two breakouts, breakout #1 is 1-40 whilst breakout2 is 41-80. The
+LEDs are numbered from 100-103.
+
+ISH UART are named as: IURT.
+ISH I2C are named as:IIC.

+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

+The number of json objects in layout should be equal to the pin_count.

+phyBOARD-Wega    {#phyboard-wega}
+=============
+
+The phyBOARD-Wega for phyCORE-AM335x is a low-cost, feature-rich software
+development platform supporting the Texas Instruments AM335x microcontroller.
+
+Moreover, due to the numerous standard interfaces the phyBOARD-Wega AM335x can
+serve as bedrock for your application. At the core of the phyBOARD-Wega is the
+PCL-051/phyCORE-AM335x System on Module (SOM) in a direct solder form factor,
+containing the processor, DRAM, NAND Flash, power regulation, supervision,
+transceivers, and other core functions required to support the AM335x
+processor. Surrounding the SOM is the PBA-CD-02/phyBOARD-Wega carrier board,
+adding power input, buttons, connectors, signal breakout, and Ethernet
+connectivity amongst other things.
+
+There are (for example) some expansion boards available for the phyBOARD-Wega:
+- Power Module (PEB-POW-01)
+- Evaluation Board (PEB-EVAL-01)
+- HDMI Adapter (PEB-AV-01)

+Interface notes
+---------------
+
+**SPI**
+Spi0 can be used over pins on X69 connector. There are no more spi-devices.
+Independent of the given index in mraa_phyboard_spi_init_pre() function,
+it will be always initialized spi0.
+
+**I2C**
+/* TODO */
+
+**UART**
+Uart0 can be used over pins on X69 connector or serial port on Evaluation Board.
+The other Uarts not have been tested yet. This is a small TODO for future.
