Clone your Sensor-Watch repository to this directory (submodules won't work!):
git clone https://github.com/joeycastillo/Sensor-Watch
Use Docker Compose to build and run the emulator:
docker-compose up
The emulator is available at http://localhost:8000/watch.html
To build the native firmware, set the BUILD_ACTION environment variable to native:
BUILD_ACTION=native docker-compose up
These commands obviously work on the previously cloned Sensor-Watch directory, that is mounted to the container, so if you want to preserve a build, you should move it away from Sensor-Watch/movement/make/build before running docker-compose again.
