+# ----------------------------------------------------------------------
+
+# FEATURES:
+# * invokes upstream fetch on each local fetch
+#   (unless the optional 'nice' setting is enabled)
+# * can force a fetch (ignoring 'nice' value) from server CLI
+
+# INSTRUCTIONS:
+#
+# * uncomment 'upstream' in the ENABLE list in the rc file.
+# * add option lines to conf file.  For example:
+#
+#       repo git
+#           R                       =   @all
+#           RW+ my-company/         =   @developers
+#
+#           option  upstream.url    =   https://git.kernel.org/pub/scm/git/git.git
+#           option  upstream.nice   =   120
+#
+# * to force a fetch on the server shell (or via cron), run this command:
+#       gitolite ../triggers/upstream fetch reponame
+
+# ADDITIONAL NOTES:
+# * restrict local pushes to a namespace that the upstream won't use
+#   (otherwise the next fetch will wipe them out)
+# * if the upstream URL changes, just change the conf and push admin repo
+# * the 'nice' setting is in minutes and is optional; it is the minimum
+#   elapsed time between 2 upstream fetches.
+
+# USAGE EXAMPLE:
+#
+# Let's say you want to keep a read-only local mirror of all your github repos
+# on your local gitolite installation.  Assuming your github usernames are the
+# same as your local usernames, and you have updated GIT_CONFIG_KEYS in the rc
+# file to allow 'config' lines, you can do this:
+#
+#   repo github/CREATOR/..*
+#       C   = @all
+#       R   = @all
+#       option upstream.url                         =   https://github.com/%GL_REPO.git
+#       option upstream.nice                        =   120
+#       config url.https://github.com/.insteadOf    =   https://github.com/github/
+#
+# Now you can make local, read-only, clones of all your github repos with
+#
+#   git ls-remote gitolite:github/sitaramc/gitolite
+#   git ls-remote gitolite:github/sitaramc/hap
+#   (etc)
+#
+# and if milki were also a user on this gitolite instance, then
+#
+#   git ls-remote gitolite:github/milki/xclip
+#   git ls-remote gitolite:github/milki/ircblogger
+#   (etc)
