While technically not a requirement, key elements of CodeStream’s functionality depend on your repository being managed by Git, or a Git hosting service like GitHub. If you’re not using Git, CodeStream will not be able to connect the codemarks you create to the appropriate blocks of code in your source files.
Once you've installed the extension, the CodeStream view should automatically appear at the right side of your editor. If for some reason it doesn't, simply click on the CodeStream entry in your IDE's status bar. Just look for the double chat bubble icon followed by "CodeStream".
Now that you’ve got the plugin up and running, you’re ready to sign up and create a team!
