-## Configuration
-
-Go to [Configuration](configuration.md) in order to see how to configure.
-
-
 ## Usage
 
-Run phpDocumentor and set template as `vendor/nelson6e65/phpdoc-vuepress/data/templates/vuepress`:
+First, you need to [prepare your project to use phpDocumentor and VuePress to generate your API documentation](configuration.md).
 
+After that, using that configuration you only need to generate the markdown pages from your code with **phpDocumentor** and then build your **VuePress** documentation:
 
 ```bash
-phpdoc -d="src/" -t="docs/api/" --template="vendor/nelson6e65/phpdoc-vuepress/data/templates/vuepress"
-```
+$ phpdoc # This will use the `phpdoc.dist.xml` config file
 
-> More information about the available arguments can be found at [running phpDocumentor](http://www.phpdoc.org/docs/latest/guides/running-phpdocumentor.html).
+$ vuepress build docs # Where `docs/` is the directory you configured
+```
 
+Done! Your API documentation is live!
 
-Then, you can update your VuePress pages with `vuepress` for your docs:
+::: tip
+If you already have a default [VuePress configuration](configuration.md#configuring-vuepress) and you want just quickly run phpDocumentor, you can use:
 
 ```bash
-vuepress build docs # if you installed vuepress globally
+phpdoc -d="src/" -t="docs/api/" --template="vendor/nelson6e65/phpdoc-vuepress/data/templates/vuepress"
 ```
 
+This assumes:
+
+- PHP sources are in: `src/`,
+- VuePress documentation is located in `docs/`,
+- VuePress will use `/api` route for the API documentation and sidebar is (/will be) configured with the files generated by phpDocumentor.
 
+Please, check the [Configuration page](configuration.md) for examples and guides instead.
