+=============================================
+working with RhodeCode and mercurial subrepos
+=============================================
+
+example usage of Subrepos with RhodeCode::
+    
+    ## init a simple repo
+    hg init repo1                                                                                                                                                                                         
+    cd repo1
+    echo "file1" > file1
+    hg add file1 
+    hg ci --message "initial file 1"
+        
+    #clone subrepo we want to add
+    hg clone http://rc.local/subrepo
+
+    ## use path like url to existing repo in RhodeCode
+    echo "subrepo = http://rc.local/subrepo" > .hgsub
+
+    hg add .hgsub
+    hg ci --message "added remote subrepo"
+
+    
+
+In file list of repo1 you will see a connected subrepo at revision it was
+during cloning.
+Clicking in subrepos link should send you to proper repository in RhodeCode
+
+cloning repo1 will also clone attached subrepository.
+
+Next we can edit the subrepo data, and push back to RhodeCode. This will update
+both of repositories.
