[jzf2101]

now added to the readme

[natebrennand]

should we add a note that you need to be in the vagrant box to call this?

also, a link to an intro to SQL might be nice.

@natebrennand good point will add that do you have a resource you like I'm going to add the official tutorial for now. I split out language re logging in and running in the app since you have to log in to access the app or the db

@jzf2101, it looks like you forgot to switch off this branch before making changes
