+# INSTRUCTIONS

+#  With either a manual or brew installed chruby things should just work.
+#
+#  If you'd prefer to specify an explicit path to load chruby from
+#  you can set variables like so:
+#
+#    zstyle :omz:plugins:chruby path /local/path/to/chruby.sh
+#    zstyle :omz:plugins:chruby auto /local/path/to/auto.sh
+# 
+# TODO
+#  - autodetermine correct source path on non OS X systems
+#  - completion if ruby-install exists
+
+# rvm and rbenv plugins also provide this alias
+alias rubies='chruby'
