- Using latest development versions
------------------------------------
-
-If you want to stay at the bleeding edge and use the latest, not yet released,
-version of WinSparkle, you can get its sources from public repository.
-WinSparkle uses git and and the sources are hosted on GitHub at
-https://github.com/vslavik/winsparkle
-
-WinSparkle uses submodules for some dependencies, so you have to initialize
-them after checking the tree out:
-
-    $ git clone https://github.com/vslavik/winsparkle.git
-    $ cd winsparkle
-    $ git submodule init
-    $ git submodule update
-
-Then compile WinSparkle as described above; no extra steps are required.
