It's important to note:

> TileMill has shifted to an open open source contributor model and moved to its own organization, tilemill-project.

A shift which has come a year or so after the project was abandoned by Mapbox in favor of Mapbox Studio (the official, supported successor to TileMill).

TileMill alone is still useful for creating one's own raster tile set, as long as the application remains in working order.

However, last I checked it gave me tremendous issues running on Linux as many dependencies had become outdated.

Although, I haven't checked back in a while since I moved to Mapbox Studio.
