+
+## usage
+
+```shell
+# create a mongo service named lolipop
+dokku mongo:create lolipop
+
+# you can also specify the image and image
+# version to use for the service
+# it *must* be compatible with the
+# official mongo image
+export MONGO_IMAGE="mongo"
+export MONGO_IMAGE_VERSION="2.8.21"
+dokku mongo:create lolipop
+
+# get connection information as follows
+dokku mongo:info lolipop
+
+# lets assume the ip of our mongo service is 172.17.0.1
+
+# a mongo service can be linked to a
+# container this will use native docker
+# links via the docker-options plugin
+# here we link it to our 'playground' app
+# NOTE: this will restart your app
+dokku mongo:link lolipop playground
+
+# the above will expose the following environment variables
+#
+#   MONGO_URL=mongo://172.17.0.1:27017
+#   MONGO_NAME=/playground/DATABASE
+#   MONGO_PORT=tcp://172.17.0.1:27017
+#   MONGO_PORT_27017_TCP=tcp://172.17.0.1:27017
+#   MONGO_PORT_27017_TCP_PROTO=tcp
+#   MONGO_PORT_27017_TCP_PORT=27017
+#   MONGO_PORT_27017_TCP_ADDR=172.17.0.1
+
+# you can customize the environment
+# variables through a custom docker link alias
+dokku mongo:alias lolipop MONGO_DATABASE
+
+# you can also unlink a mongo service
+# NOTE: this will restart your app
+dokku mongo:unlink lolipop playground
+
+# you can tail logs for a particular service
+dokku mongo:logs lolipop
+dokku mongo:logs lolipop -t # to tail
+
+# finally, you can destroy the container
+dokku mongo:destroy playground
