+MAA - Low Level Skeleton Library for Communication on Intel platforms
+==============
+
+Library in C/C++ to interface with Galileo & other Intel platforms, in a
+structured and sane API with port nanmes/numbering that match boards & with
+bindings to javascript & python.
+
+The intent is to make it easier for developers and sensor manufacturers to map
+their sensors & actuators on top of supported hardware and to allow control of
+low level communication protocol by high level languages & constructs.
+
+## API
+
+These interfaces allow you to interact with all libmaa functionality. The C++
+classes directly wrap the C API and provide a near 1:1 mapping of
+functionality.

+### Hello Maa
+@snippet hellomaa.c Interesting
+
+## Supported platforms
+
+Specific platform information for supported platforms is documented here:
+
+- @ref galileorevd
+
+### ENV RECOMENDATIONS
+
+All of these are 'optional', however they are recommended. Only a C compiler,
+cmake, libm and pthreads are technically required to compile.
+
+- Swig 3.0.1+ built with node.js & python support (0.10.x)
+- doxygen
+- sphinx (requires doxygen)
+- pygments
+
+## COMPILING
+
+More information on compiling is @ref building page
+
+## CONTRIBUTING
+
+Please see the @ref contributing page
+
+## API Changelog
+
+This changelog is meant as a quick & rough guide to what has changed between
+versions. The API is now fairly stable but when new calls/features are added
+they are listed here. Anything pre 0.2.x is ignored.
+
+**0.2.9**
+  * Add global maa.h & maa.hpp headers
+  * usage of "gpio.h" is not legal you need to use "maa/gpio.h" unless adding
+    -L/usr/include/maa
+
+**0.2.8**
+  * Added maa_set_priority call
+  * Added mmap gpio call maa_gpio_use_mmaped
+
+**0.2.7**
+  * C++ API now uses basic types and not unistd types as C
+  * Clearer and consistent use of unistd tpyes in C api
+
+**0.2.6**
+  * C++ examples added, using c++ headers/api.
+  * moved to open instead of fopen in all modules
+  * rename maa_check functions and made them internal to maa only.
+  * removed "export" functions from api
+  * Intel Galileo Gen 1 (rev d) fixes, incorrect definition of some items
+  * SPI, implementation completed.
+  * I2C internal function, completed.
+  * PWM fix bug in period set method.
+  * Swig upstream can be used for building.
+  * No longer builds docs on default cmake, needs flag
+  * GPIO/PWM ownership guard prevents closing on existing pins, still can be forced.
+
+**0.2.5**
+  * C++/Python/Node Enums/const names now do not contain MAA_GPIO
+  * Enum type declaration for C++ changed
+  * Python/Node get_version() -> GetVersion()
+  * i2c read calls don't use const char* and i2c write calls do
+
+**0.2.4**
+  * All maa_ contexts now are pointers to the actual struct which is not
+    delcared in the header. The only end user change is that instead of
+    returning a type maa_gpio_context pointer maa_gpio_init() now returns a
+    maa_gpio_context (which is actually a pointer to struct _gpio internally).
+  * C++ API is available, use the .hpp headers and add stdc++  to the linker
+    flags.
+  * Initial SPI implementation is provided
+
+**0.2.3**
+  * maa_aio_read_u16() -> maa_aio_read()
+  * maa_aio_read() now returns a uint16_t instead of an unsigned int
+
+**0.2.2**
+  * First version with API considered 'stable'
