how do I create a server?

1. Make shit in SteamCMD(login anonymous; app_update 4020 validate)
2. Set up start.bat
--
@echo off
cls
echo Protecting srcds from crashes...
echo If you want to close srcds and this script, close the srcds window and type Y depending on your language followed by Enter.
title srcds.com Watchdog
:srcds
echo (%time%) srcds started.
start /wait srcds.exe -console -game garrysmod +map (your map) +maxplayers (2-128) +gamemode sandbox
echo (%time%) WARNING: srcds closed or crashed, restarting.
goto srcds
--
3. Load addons collection through workshop.lua
4. Personal scripts in the garrysmod/addons folder?
5. Launch it on remote host(idk how) or your pc and you're ready to go. :3
