 ## Usage and configuration
 
-For this project to work smoothly, you must have in your working directory a file named **commiter.yml**. In this file you must pass the commit convention that you want to use, following the example:
+This program has a cli that you can take advantage of. Running `commit --help`
+will show you the usage and options for your commit. All of them are optional
+for the sake of not losing your precious time.
+
+```bash
+  $ commit -h
+  usage: generator.py [-h] [--co-author CO_AUTHOR] [--no-generate NO_FILE]
+                    [--convention {angular,changelog,symphony,message}]
+
+  A commit formatter tool to help you follow commit conventions.
+
+  optional arguments:
+    -h, --help            show this help message and exit
+    --co-author CO_AUTHOR
+                          make your friend an co-author to the commit
+    --no-generate NO_FILE
+                          disables the creation of a commiter.yml file
+    --convention {angular,changelog,symphony,message}
+                          Selects a convention to be used for the commit.
+                          Required if there is no commiter.yml file.
+```
+
+So, if you want to write a co-authored commit, you should use:
+
+```bash
+$ commit --co-author "foo bar doritous <foobar@douritos.com>"
+```
+
+Or if you are using this for the first time in your project:
+
+```bash
+$ commit --convention changelog
+```
+
+To work even more smoothly, have in your working directory a file named **commiter.yml**. In this file you must pass the commit convention that you want to use, following the example:
