Documentation, said Riona MacNamara at the beginning of her Open
Source
Summit Japan 2019 talk, is the superpower that we can use to energize users
and developers; it is an important part of the creation of a vibrant and
inclusive community. While there are a number of roadblocks that can impede
participation in a development community, many of those can be addressed
with better documentation. The talk was a call for all projects to think
about what they are trying to accomplish and to ensure that their
documentation is helping to get there.
