+Docker Image
+------------
+
+This documentation provides an overview of the Dockerfile used to build an image containing all the necessary packages required for building |Op_oss|. The resulting image can be used as a development environment.
+
+**Usage**
+
+#. Clone the |Op_oss| project
+
+#. At the root level (the folder containing the repo), execute the following command
+
+   .. code-block::
+
+      docker build -f ./repo/utils/Dockerfile -t <DockerImageName> .
+
+   .. note:: The Dockerfile assumes the name of the repository as "repo". The command and the Dockerfile should be modified accordingly, if different name is used
