I had understood the glitch_readme.md would appear only up till you remix it, and then your remixed version would have the base project readme? Is this not the case?
I could actually see the use of a
* Directory readme that is like an app store style pitch to use your project
* Glitch readme that is a glitch specific manual for using your project after a remix
* Ability to view the base github readme, as the authoritative full support
Any tips on how others deal with this, would be welcomed!
