 The recommended way to get the Bitnami Airflow Exporter Docker Image is to pull the prebuilt image from the [Docker Hub Registry](https://hub.docker.com/r/bitnami/airflow-exporter).
 
 ```console
-$ docker pull bitnami/airflow-exporter:latest
+docker pull bitnami/airflow-exporter:latest
 ```
 
 To use a specific version, you can pull a versioned tag. You can view the [list of available versions](https://hub.docker.com/r/bitnami/airflow-exporter/tags/) in the Docker Hub Registry.
 
 ```console
-$ docker pull bitnami/airflow-exporter:[TAG]
+docker pull bitnami/airflow-exporter:[TAG]
 ```
 
 If you wish, you can also build the image yourself by cloning the repository, changing to the directory containing the Dockerfile and executing the `docker build` command. Remember to replace the `APP`, `VERSION` and `OPERATING-SYSTEM` path placeholders in the example command below with the correct values.
 
 ```console
-$ git clone https://github.com/bitnami/containers.git
-$ cd bitnami/APP/VERSION/OPERATING-SYSTEM
-$ docker build -t bitnami/APP:latest .
+git clone https://github.com/bitnami/containers.git
