+# Setting up a local-testnet with Docker
+
+First and foremost, one needs to build the **seednode** & **node** images. Hence, the **_build.sh_**
+script is provided. This can be done, by invoking the script or building the images manually.
+
+```
+./build.sh  # (Optional) Can be ignored if you already have the images stored in the local registry.
+./setup.sh  # Will setup the local-testnet.
+./clean.sh  # Will stop and remove the containers related to the local-testnet.
+
+Optionally
+./stop.sh   # Will stop all the containers in the local-testnet.
+./start.sh  # Will start all stopped containers from the initial local-testnet.
+```
