-Inspired by [localtunnel](https://github.com/localtunnel/localtunnel) and [ngrok](https://ngrok.io/), except `bore` is intended to be a highly efficient, unopinionated tool for real production workloads that is simple to install and use, with no frills attached.
+Like [localtunnel](https://github.com/localtunnel/localtunnel) and [ngrok](https://ngrok.io/), except `bore` is intended to be a highly efficient, unopinionated tool for forwarding TCP traffic that is simple to install and easy to self-host, with no frills attached.
 
 ## Detailed Usage
 
+This section describes detailed usage for the `bore` CLI command.
+
+### Local Forwarding
+
 TODO
 
+### Self-Hosting
+
+As mentioned in the startup instructions, there is an public instance of the `bore` server running at `bore.pub`. However, if you want to self-host `bore` on your own network, you can do so with the following command:
+
+```shell
+bore server
+```
+
+That's all it takes! After the server starts running at a given address, you can then update the `bore local` command with option `--to <ADDRESS>` to forward a local port to this remote server.
+
 ## Protocol
 
 There is an implicit _control port_ at `7835`, used for creating new connections on demand. This can be configured in the command-line options.
