Hey,

Today I was playing around with ERD and installed it in my Discourse dev setup on the mac and ran it. Was a bit buggy and had to reload it a few times, but was able to get it going, but needs work.

Obviously it’s huge, and needs work.

Is anyone else on the Discourse dev team or plugin developers are using ERD or another package similar to ERD to create entity-relationship diagrams for Discourse?

Thanks!

What is the ERD application used here?  
Is this a Discourse plugin?
