+# Goal
+- Combine map exploration and wiki reading.
+
+## Motivation
+- I am a map addict. While exploring Google maps, I keep a chrome tab open for checking out random places. 
+- Having a handy tool to quickly look up at wiki page of random locations would be a plus.
+
+
+## Quick remote access
+- Use `ngrok` for frontend, `ngrok http 3000` (Since it doesnt have the password issue)
+- Use `localtunnel` for backend, `ngrok http 8004` (I don't want remote users to have to enter password or click on a suspicious looking link).
+- It works, I tested it on my phone, but it doesn't work on sandbox, most likely due to sandbox's requirement of `Authentication` from backend. Throws an `Error 511`.
