+# Using
+
+linkwallet is a 100% web-driven app. After running, hit the web interface
+on port 8109 (docker using the sample docker-compose.yml) or 8080 (default
+on binary).
+
+Change the port number by setting the PORT environment variable.
+
+If you put linkwallet on a separate machine, or behind a reverse proxy,
+go into the config page and set the correct BaseURL, or the bookmarklets
+will not work.
