 ## Next steps
+
+<!-- I like the idea of having a Getting started section. You may want to describe a few ways to get your feet wet with Geth (fast sync with a test net, dev mode, start a private network). -->
+
+### Fast sync a test network
+
+<!-- TODO: What happens if you don't specify? -->
+
+You learned about the `--syncmode` argument above, but you can also specify the network to sync with, by adding it as an argument. For example to fast sync with the Rinkeby test network:
+
+```shell
+geth --syncmode "fast" --rinkeby
+```
+
+To check the status of the sync, open another terminal, attach to the geth process, and open a console with the command below:
+
+<!-- TODO: Figuring out what to attach to seems difficult -->
+
+```shell
+geth attach ipc:{FILL_THIS}
+```
+
+Then at the `>` prompt, run the command below to the current state of the sync operation:
+
+```shell
+eth.syncing
+```
