Welcome to the Mowgli build guide. Here we provide a step by step guide to assembling a Mowgli OpenMower build. Note that Mowgli is not the default way to run OpenMower, and only is compatible with certain mowers.
This guide will include all steps to purchase, assemble, and program a Mowgli build, but it currently incomplete as it is still being written.
