+#### Installing Dependencies
+
+##### Troubleshooting Docker and Docker Compose
+
+  1. Confirm that Docker Daemon is running：
+
+```shell
+$ docker info
+```
+
+-   Ensure that Docker is installed. Refer to the official installation instructions for [Docker CE/EE](https://docs.docker.com/get-docker/).
+
+-   Start the Docker Daemon if it is not already started.
+
+-   To run Docker without `root` priveleges, create a user group labeled `docker`, then add a user to the group with `sudo usermod -aG docker $USER`. Log out and log back into the terminal for the changes to take effect. For more invormation, see the official Docker documentation for [Managing Docker as a Non-Root User](https://docs.docker.com/engine/install/linux-postinstall/#manage-docker-as-a-non-root-user).
+
+  2. Check the version of Docker-Compose
+
+```shell
+$ docker-compose version
+
+docker-compose version 1.25.5, build 8a1c60f6
+docker-py version: 4.1.0
+CPython version: 3.7.5
+OpenSSL version: OpenSSL 1.1.1f  31 Mar 2020
+```
+
+-   To install Docker-Compose, see [Install Docker Compose](https://docs.docker.com/compose/install/)
+
+##### Install jq
