Tracks the specified branch. Better use refs/heads/<branchName>
E.g. master , development

Tracks multiple branches in csv format
E.g. development, master, */master, *feature, feature/**

E.g. **

<Wildcards>

• "*" is recognized as a wildcard
• "**" is recognized as wildcard that includes the separator '/'

Therefore, origin/branches* would match origin/branches-foo but not origin/branches/foo, while origin/branches** would match both origin/branches-foo and origin/branches/foo
