 3. Run ``cp infra_config.yml.sample infra_config.yml``
 4. Edit infra_config.yml and put your environment values
 5. Run ``bash run.sh``
+
+Notes
+=====
+
+In infra_config.yml you may specify public key file instead of public key content, in the following way:
+
+    keypairs:
+      - name: my_key_file
+        public_key_file: /home/<my_user>/.ssh/<key_file>
+
+Do not specify both 'public_key' and 'public_key_file', as they are mutual exclusive variables in Ansible.
