+# Docker-compose example
+
+This is a quick example that allows live development on a server. This is very basic and lacks a number of features that would be on an average site (eg fastcgi, redis, etc).
+
+It is accessible on `localhost:80`
+
+## db folder
+
+- Contains create_database.sql
+
+This is standard sql to create a database to work off. In the example of cloudM, you'd have an SQL dump or such here to populate the DB. This is referenced in `docker-compose.yaml` 
+
+```docker-compose.yaml
+volumes:
+      - "./db/:/docker-entrypoint-initdb.d"
+```
+With the specific image used (mysql:5.7) anything placed in the container at docker-entrypoint-initdb.d will be ran as sql files when the database has been created.
+
+## src
+ 
+Code lives here. The example here is a simple php file to pull some data from the DB and display it. it is mounted in the docker-compose.yaml so thus can edited on-the-fly without restarts.
+
+## docker-compose.yaml
+
+defines how everything meshes together. run the command `docker-compose up` to bring it all live, with down to tear it away. 
+
+```docker-compose.yaml
+    build: 
+      context: .
+      dockerfile: web-dockerfile
+```
+This defines that the image will be built from a file within the current directory, with web-dockerfile being the Dockerfile.
+
+## web-dockerfile
+
+Creates the docker image. It uses an image from the dockerhub, updates and then enables the mysqli module for php to allow connections. The command `docker-php-ext-install X' is provided by the creators of the docker image.
