Problem: The setup guide offers a cumbersome way to manage processes.

Solution: Document how to manage processes using Monit.

+### Member: Start BigchainDB and Tendermint using Monit
+
+This section describes how to manage the BigchainDB and Tendermint processes using [Monit][monit] - a small open-source utility for managing and monitoring Unix processes.
+
+This section assumes that you followed the guide down to the [start MongoDB section](member-start-mongodb) inclusive.
+
+Install Monit:
+
+```
+sudo apt install monit
+```
+
+If you installed the `bigchaindb` Python package, you should have the `bigchaindb-monit-config` script in your `PATH` now.
+
+Run the script:
+
+```
+bigchaindb-monit-config
+```
+
+The script builds a configuration file for Monit.
+
+Run Monit as a daemon, instructing it to wake up every second to check on processes:
+
+```
+monit -d 1
+```
+
+It will run the processes and restart them when they crash. If the root `bigchaindb_` process crashes, Monit will also restart the Tendermint process.
+
+Check the status by running `monit status` or `monit summary`.
+
+By default, it will collect program logs into the `~/.bigchaindb-monit/logs` folder.
+
+Consult `monit -h` or [the Monit documentation][monit-manual] to know more about the operational power you've just got the taste of.
+
+Check `bigchaindb-monit-config -h` if you want to arrange a different folder for logs or some of the Monit internal artifacts.

 ## How Others Can Access Your Node
 
 If you followed the above instructions, then your node should be publicly-accessible with BigchainDB Root URL `http://hostname:9984` (where hostname is something like `bdb7.canada.vmsareus.net` or `17.122.200.76`). That is, anyone can interact with your node using the [BigchainDB HTTP API](http-client-server-api.html) exposed at that address. The most common way to do that is to use one of the [BigchainDB Drivers](./drivers-clients/index.html).
