+* php7.2-acpu
+* php7.2-yaml

+
+## Running local Grav installation
+
+This assumes you have already downloaded a Grav package into a local folder. This is the best way to run Grav if you want to have your changes persisted between restarts of the docker container.
+
+```
+docker run -v /local/grav/install:/var/www/html:cached -p 8000:80/tcp grav:latest
+```
+
+To run in the current directory you can use:
+
+```
+docker run -v `pwd`:/var/www/html:cached -p 8000:80/tcp grav:latest
+```
+
+Point browser to `http://localhost/8000` to access your Grav site
