+### Configure runners (optional)
+
+If you're using runners, you'll need to configure them after completing the UI-based setup of your GitLab instance. You can do this either by creating config.toml in each runner's bind-mounted folder (example below), or by "docker exec'ing" into each runner container and running ```gitlab-container register``` interactively to generate config.toml.
+
+Sample runner config.toml:
+```
+concurrent = 1
+check_interval = 0
+
+[[runners]]
+  name = "myrunner1"
+  url = "https://gitlab.example.com"
+  token = "<long string here>"
+  executor = "docker"
+  [runners.docker]
+    tls_verify = false
+    image = "ruby:2.1"
+    privileged = false
+    disable_cache = false
+    volumes = ["/cache"]
+    shm_size = 0
+  [runners.cache]
+```
+
+1. You'll note that I setup 2 runners. One is locked to a single project (this cookbook build), and the other is a shared runner. No particular reason, I just wanted to get experience with each type. You could easily customize this to your use case.
