+### Running the Solver
+
+Run the following commands from the root directory (you need `docker` installed)
+
+```bash
+docker build -t solver .
+```
+
+Once it finish building the image
+
+```bash
+docker run -it -e [PRIVATE_KEY=SOME_PK_YOU_OWN | MNEMONIC=SOME_MNEMONIC_YOU_OWN] solver
+```
+
+The solver is run using `pm2` inside the docker container so `pm2` commands can still be used inside a container with the docker exec command:
+
+```bash
+# Monitoring CPU/Usage of each process
+docker exec -it <container-id> pm2 monit
+# Listing managed processes
+docker exec -it <container-id> pm2 list
+# Get more information about a process
+docker exec -it <container-id> pm2 show
+# 0sec downtime reload all applications
+docker exec -it <container-id> pm2 reload all
+```

 ### Logging
 
-The application utilizes a custom Logger class for logging. You can adjust the log level and format by modifying the Logger instantiation in index.ts.
+The application utilizes a custom Logger class for logging. You can adjust the log level and format by modifying the Logger instantiation in index.ts. By default it will log to `stdout` in a human-readable format using the `INFO` level.
+
+You can customize the logging destination by using a pino transport of your choosing. There's an example for logging to a Syslog server running on `localhost` commented in [logger.ts](logger.ts). Check out the [pino transports docs](https://github.com/pinojs/pino/blob/main/docs/transports.md) for other available transports.
