 ### Requirements (ensure you are using the latest)
 - [ESX Legacy](https://github.com/esx-framework/esx-legacy)
-- [Spawnmanager](https://github.com/citizenfx/cfx-server-data/tree/master/resources/%5Bmanagers%5D/spawnmanager)
-
-- [OxMySQL](https://github.com/overextended/oxmysql/) or [MySQL Async 3.3.2](https://github.com/brouznouf/fivem-mysql-async/releases/tag/3.3.2)
-
-### Installation
-- Modify your ESX config with `Config.Multichar = true`
-- Set your database name for `Config.Database` in server/main.lua
-- Run `esx_multicharacter.sql` into your database
-- All owner and identifier columns should be set to `VARCHAR(60)` to ensure correct data entry
-	- The resource will attempt to set columns automatically
-
-### Changing character prefix
-- Each character is created a modified identifier (char#:identifier)
-- Due to an oversight, ESX Legacy only supports a prefix with a length of 4
-- If you change the length, refer to https://github.com/esx-framework/esx-legacy/blob/main/%5Besx%5D/es_extended/server/classes/player.lua#L17
-- Modify this line to the following
-```lua
-if Config.Multichar then self.license = 'license:'..identifier:sub(identifier:find(':'), identifier:len()) else self.license = 'license:'..identifier end
-```

-	- Setup correctly you can break your loops and trigger them again after loading
