 1. The Docker Compose files and configurations are located in GitHub.  If you do not have Git installed, download the appropriate [Git client](https://git-scm.com/downloads) for your OS.  Now clone the repository:
 
-   ```
+```
 git clone https://github.com/IBM-Blockchain/fabric-images.git
 ```
 2. Go into the docker-compose directory:
 
-   ```
+```
 cd fabric-images/docker-compose

 3. Set the environment by executing the setenv.sh script:
 
-   ```
+```
 . setenv.sh
