Most modders include a license or readme.txt inside the RAR. If you plan to re-upload or modify their work, check if they allow it.
Modders often download PBOs to study how others scripted a specific mission or configured a vehicle. Use Eliteness or PBO Manager to extract the files.
Most mods downloaded from external sites (like Armaholic or DayZ Launcher ) come as .rar files. Extract the .rar to your game's root directory.
Remember that for multiplayer, PBOs must be "signed" with a Bikeypa file so the server knows they haven't been tampered with. ⚠️ Safety & Best Practices
Before overwriting any PBO in your game folder, copy the original to a safe location.
Look for config.cpp (settings) or .sqf files (scripts) to understand the logic. 3. Server Management
