 ### Usage
 ```
 $ docker-gen
-```
-**Usage: docker-gen [options] template [dest]**
+Usage: docker-gen [options] template [dest]
 
 Generate files from docker container meta-data
 
 Options:
-    -config value
-            config files with template directives. Config files will be merged if this option is specified multiple times. (default [])
-    -endpoint string
-            docker api endpoint (tcp|unix://..). Default unix:///var/run/docker.sock
-    -interval int
-            notify command interval (secs)
-    -keep-blank-lines
-            keep blank lines in the output file
-    -notify restart xyz
-            run command after template is regenerated (e.g restart xyz)
-    -notify-sighup docker kill -s HUP container-ID
-            send HUP signal to container.  Equivalent to docker kill -s HUP container-ID
-    -only-exposed
-            only include containers with exposed ports
-    -only-published
-            only include containers with published ports (implies -only-exposed)
-    -tlscacert string
-            path to TLS CA certificate file (default "/Users/jason/.docker/machine/machines/default/ca.pem")
-    -tlscert string
-            path to TLS client certificate file (default "/Users/jason/.docker/machine/machines/default/cert.pem")
-    -tlskey string
-            path to TLS client key file (default "/Users/jason/.docker/machine/machines/default/key.pem")
-    -tlsverify
-            verify docker daemon's TLS certicate (default true)
-    -version
-            show version
-    -watch

 Arguments:
-    template - path to a template to generate
-    dest - path to a write the template.  If not specfied, STDOUT is used

 Environment Variables:
-    DOCKER_HOST - default value for -endpoint
-    DOCKER_CERT_PATH - directory path containing key.pem, cert.pm and ca.pem
-    DOCKER_TLS_VERIFY - enable client TLS verification]

 If no `<dest>` file is specified, the output is sent to stdout.  Mainly useful for debugging.

 ### Configuration file
 
 Using the -config flag from above you can tell docker-gen to use the specified config file instead of command-line options.  Multiple templates can be defined and they will be executed in the order that they appear in the config file.
 
 An example configuration file, **docker-gen.cfg** can be found in the examples folder.
