I'm happy to announce that Maru has been fully open-sourced under The Maru OS Project!
There are many reasons that led me to open-source Maru, but a particularly important one is expanding Maru's device support with the help of the community.
If you'd like to help out with a device port (even just offering to test a new build helps a lot), let the community know on the device port planning list. We currently have a few Nexus, LG, and Motorola builds being planned. If you don't see your device on there and would like to help with development or testing, please do chip in and we'll get it added to the list.
Looking forward to seeing Maru on some new devices!
