Deploy DO Django about docs

[luxpir]

Hi - was directed to this issue, hopefully relevant, here's the discord query:

Got set up with Corporate in the end, thanks again @Sm0ke - made a few customisations and it's going OK, 
but when I committed the updates the deployment worked, 
but I had to run migrate and createsuperuser again to get it working. 

Assume there's a better way of doing that?

Apparently this happens automatically on Render, but not on DO - any solutions you can think of? I wouldn't like to lose every user and wipe the tables every time I updated the app!

Thanks!
