 ## Jekyll Documentation theme
 
 Build the site to see the instructions for using it. Or just go here: [http://idratherbewriting.com/documentation-theme-jekyll/](http://idratherbewriting.com/documentation-theme-jekyll/)
+
+## Running the site in Docker
+
+You can also use Docker to directly build and run the site on your local machine. Just clone the repo and run the following from your working dir:
+
+```
+docker build --no-cache -t mydocs .
+```
+
+Once the build is complete, you can mount and run the whole site as follows:
+
+```
+docker run -v "$PWD:/src" -p 4000:4000 mydocs serve -H 0.0.0.0
+```
+This is perhaps the easiest way to see how your site would actually look.
