 --------------------------
 
-## What you'll need
+## Using Docker
+
+The easiest way of launching a client node is using the [official docker image](https://hub.docker.com/r/nuls/client-node/)
+
+[Docker](https://www.docker.com/) is a tool designed to make it easier to create, deploy, and run applications by using containers. Containers allow a developer to package up an application with all of the parts it needs, such as libraries and other dependencies, and ship it all out as one package.
+
+You can run a full nuls client node with a single line:
+```sh
+  docker run --name nuls-node -d \
+    -p 127.0.0.1:6001:6001 \
+    -v /tmp/nuls/logs:/nuls/logs \
+    -v /tmp/nuls/data:/nuls/data \
+    nuls/client-node:1.0.1
+```
+
+By default the client interface is accessible in the port `6001`, so once the node is running, check that everything is working visiting the url [localhost:6001](http://localhost:6001) in your browser.
+
+After that, try open the commands shell of the node by running:
+```sh
+  docker exec -it nuls-node /nuls/bin/cmd.sh
+
+  # Then get a list of available shell commands
+  >> help
+```
+
+To see the node logs run:
+```sh
+  docker logs -f nuls-node
+```
+
+All the data generated by the node is stored in the mounted volume `/tmp/nuls/data`.
+You can read more details about how to configure the client node container [here](https://hub.docker.com/r/nuls/client-node/).
