 The functionalities:
  * Calculates 1s average of sum vector from 3d acceleration data
- * Offers an API for subscribing the values
- * Blinks the LED every time it publishes
+ * Offers an API for subscribing to the value
+ * Blinks the LED every time it publishes the calculations
+ * Stops data collection, publicking and blinking if there are no subscribers

+Requires the Movesense SDK.
 
-Compile inside the SDK:
+Follow the instructions at https://bitbucket.org/suunto/movesense-device-lib/src/master/
+ 1. Install the dependencies: `cmake`, `ninja`, GNU toolchain for ARM embedded and `nrfutil`
+ 2. `git clone git@bitbucket.org:suunto/movesense-device-lib.git`
+ 3. `git clone http://matetelki.eu:3000/denes/movesense_exercise.git`
+ 4. `cd movesense-device-lib`
+
+Compile and generate packages with linux inside the SDK:
  1. `mkdir excerciseBuild`
  2. `cd excerciseBuild`
- 3. `cmake -G Ninja -DMOVESENSE_CORE_LIBRARY=../MovesenseCoreLib/ -DCMAKE_TOOLCHAIN_FILE=../MovesenseCoreLib/toolchain/gcc-nrf52.cmake PATH_TO_EXCERCISE_DIR`
- 4. `ninja`
+ 3. `cmake -G Ninja -DMOVESENSE_CORE_LIBRARY=../MovesenseCoreLib/ -DCMAKE_TOOLCHAIN_FILE=../MovesenseCoreLib/toolchain/gcc-nrf52.cmake ../../movesense_exercise`
+  * Add ` -DCMAKE_BUILD_TYPE=Release ` for release builds.
+ 4. Issue `ninja` to compile
+ 5. Create OTA firmware update package with `ninja dfupkg`
+
+Run simulations with Windows, inside the SDK:
+ 1. `mkdir simuBuild`
+ 2. `cd simuBuild`
+ 3. `cmake -G "Visual Studio 15 2017" -DMOVESENSE_CORE_LIBRARY=../MovesenseCoreLib/ ../../movesense_exercise`
+ 4  `ninja`
+ 5. If you have an account at simbio, download the `acceleration.cvs` test data
+ 6. Run the simulation build: `Debug/Movesense.exe`
+ 7. Subscribe and observe the behaviour from another shell with: `tools/wbcmd (Win).exe --port TCP127.0.0.1:7044 --path /Exercise/Sumvector/Denes --op subscribe`
+
+The OTA firmware update package is available at: http://matetelki.eu/movesense_exercise
