 Each Seafile library behaves like a Git repository. It has its own unique history, which consists of a list of commits.
 A commit points to the root of a file system snapshot. The snapshot consists of directories and files.
 Files are further divided into blocks for more efficient network transfer and storage usage.
+However, Seafile doesn't rely on Git to run.
 
+Source repositories for Seafile components
+==========================================
+
+Each component of Seafile has its own source code repository on Github.

+* Sync client daemon (this repository): https://github.com/haiwen/seafile
+* Sync client GUI: https://github.com/haiwen/seafile-client
+* Server core: https://github.com/haiwen/seafile-server

+Before version 6.0, the source code of "sync client daemon" and "server core" are mixed together in https://github.com/haiwen/seafile.
+But after 6.0 version, the server core is separated into its own repository.
+For this reason, the sync client daemon repository is still the "front page" for Seafile project on Github.
