We've looked for ways to make our team discussions and process more visible and accessible to all users. We recently switched from Google Docs to HackMD. HackMD offers a great unified Markdown editor/preview which is familiar and well-suited to our needs. Our meeting records have improved a lot over a short period and as a result we are able to be better accountable to each other as a team.

How I use HackMD in Open Source projects

One of the major properties of successful open source projects is their ability to be transparent with their communities.
This involves everything from open governance, to values, to technical direction.
