Hello I logged in heroku and I want to push my own created server not their demo, I typed **cd c:\server** and then **git push heroku maste**r but I get this error: **Not a git repository (or any of the parent directories): .git**
I tried push demo heroku and everything worked fine maybe problem in json files?
