Git can locally ignore files

What interested me about this post was not so much the local git workflow tips (which are cool!), but the Markdown tools the author uses with Helix.

Especially Harper! I had heard of it before, and it’s possible I dismissed it because it was an Automattic project. However, they do have some fantastic apps. And Harper seems really cool to use with Markdown (and maybe other languages?) in Helix. Definitely recommended (until I find out they’re somehow using my data for sketchy purposes or something).

Elsewhere, the author goes into a lot more detail about how he uses Helix.
