+### Smaller cache with infrequent updates
+For speed, it is better to use a smaller cache, and to update only when you *want* to test with the latest Nim compiler.
+
+For a quick set-up, fork this https://github.com/cdunn2001/nim-project-template[nim-project-template], attach a TravisCI Webhook, and `git push`. To update the nim compiler, just clear the cache via the *settings* drop-down at the upper-right in TravisCI, and rebuild.
