+### Download from a custom host
+
+By default `patchsplit` talks to `github.com`, or `gitlab.com` with `--gitlab`.
+Pass `--host <host>` to point it at another host that serves the same patch
+endpoints, such as a GitHub Enterprise Server or a self-hosted GitLab instance:

+
+The host is a bare hostname with an optional port (for example
+`gitlab.internal:8443`); requests always use `https`. Do not include a scheme
+or a path. Combining `--host` with `--gitlab` selects the GitLab URL layout on
+the custom host, while omitting it selects the GitHub layout.
