If you want to share custom skins, for example for an important league event, there are a couple of ways to do this:

1. Use skins transfer: this means all clients will have to connect as some point to transfer their skin to all users via the server (see Sharing with Skin Transfer for further info)
2. Create an update rfcmp that you distribute to your league-before hand that either gets manually installed or can be distributed via a workshop item. 

In this guide we will be focusing on method 2: Creating an update rfcmp. 

Before getting started: what is an rfcmp?

• Simple put, an 'rfcmp' is what we call a 'package' file it contains the content you wish to install. This can be a track, a car, or even a custom HUD or UI.

For our purposes here, however, we don't need to get too into the details of what an rfcmp is, all you need to keep in mind is how to create it and then how to install and distribute it after.

The advantages of creating an update rfcmp are:

1. Clients don't have to show up early to an event just to make sure their skin gets transferred to all other clients
2. More control: the admin can check all skins and make sure no mistakes were made by the client in setting up their custom team
3. Less load on the server, no skins are transferred by the server itself and therefore it requires no extra bandwidth 

This method does require a little extra work on the part of the admin, but once you get the hang of it should be relatively easy to keep doing.
