Install and configure a markdown input filter
I'd like to be able to compose content for c.o nodes using markdown. Why? Because most of our other systems use markdown (e.g. Mattermost, GitLab, GitHub, StackExchange, MkDocs), so in some ways it has become the go-to portable format. I can copy markdown directly from StackExchange and post it into MkDocs without worrying about the formatting. This is great. Also, I can compose content on my local machine using a markdown editor, and then post it to one or more of these web-based systems later. The workflow is very nice. But c.o is not compatible with this nice workflow.
I think it'd be easy to install this: https://www.drupal.org/project/markdown
What do others think?
