Our source control integrations allows you to reference card ids in your commit messages:
$ git commit -am 'Increased size of hit boxes. Fix $3f1'
$ git commit -am 'Added animations - please review $2xr @sarah'
$ git commit -am 'Refactored god class in preparation for $5ta'
This allows you to either mark a card as done or even start a review without having to leave your terminal.
First, go to the Organization Settings and find the GitHub tab. You will then be asked to authenticate via a button. Once this succeeded, you will be able to select and connect a repository.
The procedure for Bitbucket and GitLab is fairly similar: Find the corresponding tabs in your Organization settings and find the Create Webhook Url button. This will create a url that you need to enter into your Bitbucket/GitLab settings. Follow the instructions within the settings, if you need help!
