 - Use methods of `IVCS` interface. See [pk-vcs-api](https://github.com/ProjectKaiser/pk-vcs-api) for details
-- Use `vcs.setProxy()` and `vcs.setCredentials()` if neccessary

 # Functional testing
 - To execute tests just run SVNVCSTest class as JUnit test. Tests from VCSAbstractTest class will be executed. See  [pk-vcs-test](https://github.com/ProjectKaiser/pk-vcs-test) for details
+
+# Limitations
+- According to IVCS description `IVCS.getBranches()` should return list of user-created branches. But a branch and a dir are the same for SVN. So `SVNVCS.getBranches()` returns set of first level folders of "Branches/" branch and "Trunk" branch. I.e.:
+	- Assume we have following directory structure:
+		- Branches/Br1/Folder/file.txt
+		- Branches/Br2/Folder/file.txt
+		- Trunk/Folder/file.txt
+	- Then `SVNVCS.getBranches()` method will return [Br1, Br2, Trunk]
