+You can run a Maven project by using the Maven Docker image directly, passing a Maven command to `docker run`:
 
-    docker run -it --rm --name my-maven-project -v "$(pwd)":/usr/src/mymaven -w /usr/src/mymaven %%IMAGE%%:3.3-jdk-8 mvn clean install
+```console
+$ docker run -it --rm --name my-maven-project -v "$(pwd)":/usr/src/mymaven -w /usr/src/mymaven %%IMAGE%%:3.3-jdk-8 mvn clean install
+```
 
 ## Building local Docker image (optional)
 
 This is a base image that you can extend, so it has the bare minimum packages needed. If you add custom package(s) to the `Dockerfile`, then you can build your local Docker image like this:
 
-    docker build --tag my_local_%%IMAGE%%:3.5.2-jdk-8 .
-
+```console
+$ docker build --tag my_local_%%IMAGE%%:3.5.2-jdk-8 .
+```
 
 # Reusing the Maven local repository
 
 The local Maven repository can be reused across containers by creating a volume and mounting it in `/root/.m2`.
 
-    docker volume create --name maven-repo
-    docker run -it -v maven-repo:/root/.m2 %%IMAGE%% mvn archetype:generate # will download artifacts
-    docker run -it -v maven-repo:/root/.m2 %%IMAGE%% mvn archetype:generate # will reuse downloaded artifacts
+	docker volume create --name maven-repo
+	docker run -it -v maven-repo:/root/.m2 %%IMAGE%% mvn archetype:generate # will download artifacts
+	docker run -it -v maven-repo:/root/.m2 %%IMAGE%% mvn archetype:generate # will reuse downloaded artifacts
 
 Or you can just use your home .m2 cache directory that you share e.g. with your Eclipse/IDEA:
 
-    docker run -it --rm -v "$PWD":/usr/src/mymaven -v "$HOME/.m2":/root/.m2 -v "$PWD/target:/usr/src/mymaven/target" -w /usr/src/mymaven %%IMAGE%% mvn clean package  
-
+```console
+$ docker run -it --rm -v "$PWD":/usr/src/mymaven -v "$HOME/.m2":/root/.m2 -v "$PWD/target:/usr/src/mymaven/target" -w /usr/src/mymaven %%IMAGE%% mvn clean package  
+```
 
 # Packaging a local repository with the image
 
-The `$MAVEN_CONFIG` dir (default to `/root/.m2`) could be configured as a volume so anything copied there in a Dockerfile at build time is lost.
-For that reason the dir `/usr/share/maven/ref/` exists, and anything in that directory will be copied on container startup to `$MAVEN_CONFIG`.

-To create a pre-packaged repository, create a `pom.xml` with the dependencies you need and use this in your `Dockerfile`.
-`/usr/share/maven/ref/settings-docker.xml` is a settings file that changes the local repository to `/usr/share/maven/ref/repository`,
-but you can use your own settings file as long as it uses `/usr/share/maven/ref/repository` as local repo.

 To add your custom `settings.xml` file to the image use
 
-    COPY settings.xml /usr/share/maven/ref/
+```dockerfile

 # Running as non-root
 
-Maven needs the user home to download artifacts to, and if the user does not exist in the image an extra
-`user.home` Java property needs to be set.

 For example, to run as user `1000` mounting the host' Maven repo
 
-    docker run -v ~/.m2:/var/maven/.m2 -ti --rm -u 1000 -e MAVEN_CONFIG=/var/maven/.m2 %%IMAGE%% mvn -Duser.home=/var/maven archetype:generate
