-Our cmake configure has a number of options, `cmake -i` will ask you all sorts
-of interesting questions, you can disable swig modules, build documentation
-etc...
+Our cmake configure has a number of options, cmake-gui or ccmake can show you
+all the options. The interesting ones are detailed below:
 
 Few recommended options:
 Changing install path from /usr/local to /usr
--DCMAKE_INSTALL_PREFIX:PATH=/usr
+ -DCMAKE_INSTALL_PREFIX:PATH=/usr
 
 Building debug build:
--DCMAKE_BUILD_TYPE=DEBUG
+ -DCMAKE_BUILD_TYPE=DEBUG
 
 Using clang instead of gcc:
  -DCMAKE_C_COMPILER=/usr/bin/clang -DCMAKE_CXX_COMPILER=/usr/bin/clang
 
 Building with an older version of swig (swig 2.0+) requires the disabling of javascript:
  -DBUILDSWIGNODE=OFF
+
+Disabling python module building
+ -DBUILDSWIGPYTHON=OFF
+
+Building doc, this will require sphinx & doxygen
+ -BUILDDOC=ON
+
+Using a yocto/oe toolchain
+--------------------------
+
+In order to compile with a yocto/oe toolchain use the following toolchain file.
+This works well on the edison 1.6 SDK. First source the environment file, then
+use our cmake toolchain file.
+
+~~~~~~~~~~~~~{.sh}
+source /opt/poky-edison/1.6/environment-setup-core2-32-poky-linux
+mkdir build
+cmake -DCMAKE_TOOLCHAIN_FILE=../cmake/Toolchains/oe-sdk_cross.cmake ..
+make

+
+Using coverity
+--------------
+
+Static analysis is routinely performed using coverity on libmraa's codebase.
+This is the procedure to submit a build to coverity. You'll need to install
+coverity-submit for your OS.
+
+~~~~~~~~~~~~~{.sh}
+mkdir covbuild/ && cd covbuild
+cmake -DBUILDDOC=OFF -DBUILDSWIG=OFF ..
+cmake -DBUILDDOC=OFF -DBUILDSWIG=OFF ..
+cov-build --dir cov-int make
