Please open the GIT manager.Then choose the action 'PULL changes'.
On the first dialog of a wizard there are only two points: "Use defaults for the current branch" and "Select a repository and branch manually".

Use defaults for the current branch.
In this case a getting of the changes occurs at once, using kept before parameters. Performance process will be displayed in standard progress window.

Select a repository and branch manually.
In this case process is similar a PUSH command. The wizard allows to choose one of ways of formation of parametres of a command - "Use existing remote", "Crete a new remote" or "Use arbitrary URL".

After you define remote, it will be necessary to choose a branch in which the data will be obtained from a remote repository.

If before getting data you have not commited the changes will occur automatic merge and there can be the merging conflicts. To resolve them is possible only by manual editing.
