============================================
  PASTE THIS INTO YOUR MIKROTIK TERMINAL
  (WinBox > New Terminal, or SSH)
============================================

OPTION A: One-line auto-install (fetches from GitHub):
------------------------------------------------------
/tool fetch url="https://raw.githubusercontent.com/Abdulnasserh/lakimboria-wifi/main/install.rsc" dst-path=install.rsc; /import install.rsc

NOTE: After running Option A, you must update the URL in the router:
/file set "hotspot/conf.js" contents="var config = {\r\n  loginvc : \"Weka Kodi ya Vocha kisha bonyeza Unganisha.\",\r\n  loginup : \"Weka Jina la Mtumiaji na Nywila kisha bonyeza Unganisha.\",\r\n  voucherCode : \"Kodi ya Vocha\",\r\n  setCase : \"none\",\r\n  defaultMode : \"voucher\",\r\n  theme : \"default\",\r\n  url : \"http://${localIP}:8081\",\r\n  SessionName : \"hotspot\",\r\n}\r\n"


OPTION B: Use the local install.rsc file (already has your IP):
---------------------------------------------------------------
1. Open WinBox > Files
2. Drag & drop the file: $dir\install.rsc
3. Then in Terminal run: /import install.rsc


Your PC IP: $localIP
Server will run at: http://${localIP}:8081
