 The IFM is usually locked to it's own directory, so you are not able to go
 above. You can change that by setting the `root_dir` in the scripts

 ## Configuration
+
 See [configuration](https://github.com/misterunknown/ifm/wiki/Configuration).
+
 ### authentication
+
 See [authentication](https://github.com/misterunknown/ifm/wiki/Authentication).
 
 ## Docker
+
 The docker image is based on the official php docker images (alpine version)
 and exposes port 80.
 
 ### Quickstart
+
 Build the image with this command in the top source dir:
 
-`docker build -t ifm .`
+```bash
+docker build -t ifm .
+```
 
 Afterwards you can start the docker container as follows:
 
-`docker run --rm -d --name ifm -p 8080:80 -v /path/to/data:/var/www ifm:latest`
+```bash
+docker run --rm -d --name ifm -p 8080:80 -v /path/to/data:/var/www ifm:latest
+```
 
 ### Specify user/group
+
 By default IFM runs as user www-data (uid/gid 33). If you need to change that,
 you can set the UID and GID with the following environment variables:
 
-`docker run ... -e IFM_DOCKER_UID=1000 -e IFM_DOCKER_GID=100 ifm:latest`
+```bash
+docker run ... -e IFM_DOCKER_UID=1000 -e IFM_DOCKER_GID=100 ifm:latest
+```
 
 ### Other configuration
+
 The script is located at `/usr/local/share/webapps/ifm/index.php`. By default
 the `root_dir` is set to /var/www, so you can mount any directory at this
 location. If you want to bind the corresponding host directory, you can do the
 following:
 
-`docker run --rm -i -p "8080:80" -v "/var/www:/var/www" ifm`
+```bash
+docker run --rm -i -p "8080:80" -v "/var/www:/var/www" ifm
+```
 
 The scripts configuration can be changed by adjusting the corresponding
 environment variables. For example:
 
-```docker run --rm -i -p "8080:80" -v /var/www:/var/www \
-	-e IFM_AUTH=1 -e IFM_AUTH \
-	-e IFM_AUTH_SOURCE="admin:$2y$05$LPdE7u/5da/TCE8ZhqQ1o.acuV50HqB3OrHhNwxbXYeWmmZKdQxrC" \
-	ifm
+```bash
+docker run --rm -i -p "8080:80" -v /var/www:/var/www \
+  -e IFM_AUTH=1 -e IFM_AUTH \
+  -e IFM_AUTH_SOURCE="admin:$2y$05$LPdE7u/5da/TCE8ZhqQ1o.acuV50HqB3OrHhNwxbXYeWmmZKdQxrC" \
+  ifm
 ```
