+#### Accessing remoteStorage from another machine
+
+remoteStorage clients force HTTPS for any host except `localhost`, and browsers
+block plain-HTTP requests to a LAN IP as mixed content. To connect to the dev
+remoteStorage from a browser on another machine (including production apps such
+as Inspektor), forward the ports over SSH and connect as `localhost`:
+
+    ssh -N -L 3000:localhost:3000 -L 4567:localhost:4567 <user>@<dev-host>
+
+Then use `<user>@localhost:3000` as the remoteStorage address in the client.
+WeFinger discovery and storage requests are served through the forwarded ports,
+so no TLS setup is needed.
