# Developers

Build on CAS Advanced Gang System: server and client exports, events and the NUI contract, the database tables and customising the React interface.

For your own heist, bounty, war and territory scripts, and for changing the interface.

* [Exports](/script-documentation/cas-advanced-gang/developers/exports.md) — read gangs, permissions, members, tiers and contests from your scripts.
* [Events and NUI](/script-documentation/cas-advanced-gang/developers/events-and-nui.md) — who decides what, and the messages between Lua and the interface.
* [Database](/script-documentation/cas-advanced-gang/developers/database.md) — the oxmysql tables and what they hold.
* [Customising the interface](/script-documentation/cas-advanced-gang/developers/interface.md) — rebuilding the ledger, colours, icons and text.
