+# Role Name
+
+`swarming_needs`
+
+# Description
+
+All the extra things that need to be on a test machine for Swarming to run.
+
+Right now this only works for linux machines, it will need to evolve to support
+all the platforms, at which point the platforms specific tasks should go in
+their own files, e.g. `linux.yml`.
+
+# Variables Required
+
+None.
+
+# Example Playbook
+
+```
+# Copy the authorized_keys files to all the RPis.
+- hosts: "{{ variable_hosts | default('rpis') }}"
+ user: chrome-bot
+
+ roles:
+ - swarming_needs
