For wasp-os v0.2 (M2 in the roadmap) we have focused on building the best developer experience possible.
That means there is a file system that allows developers to transfer python source code to the device and arrange for it to be executed automatically. This allows much faster development cycles. There are also many new applications together with an application launcher to hold things together.
This is supplemented with comprehensive documentation available at: https://wasp-os.readthedocs.io and which includes a comprehensive Application Writers Guide together with install instructions, a reference manual and much more.
