    Library
    Temp
    *.pidb
    *.sln
    *.userprefs
    *.csprog
    *.orig
    
    This allows you to ignore some files (you can include any files you don't want to track in ".hgignore")."
  11. Now you have to do the first commit of the repository:
    1. Check the option of Pending Files.
    2. Write a message to commit.
    3. Press the commit button.

Inviting Users to the Repository

If you are working with a team and want to share the repository:

  1. From the Bitbucket repository, you have to invite users to the repository (with their Username or Email address).
  2. The user has to accept the invitation.
  3. In SourceTree each user has to make a Clone from URL. (Copying and pasting the URL from their Bitbucket repository)
  4. Make sure each user has the correspond credentials (the BitBucket user account must have been invited) to log in to the SourceTree repository.
  5. That’s all, ENJOY IT!
