+When we're ready to allow other tilde.club IRC servers to connect to us, these are we'll need bits of information from the remote server admin.
+
+* remote IRC server IP address (if the server is behind NAT, this needs to be the external IP address)
+* port the server is listening on (preferably the SSL port)
+* the name of the remote IRC server (if it's a charybdis server, this is `name` in the `serverinfo` section of its `ircd.conf` file)
+* two passwords, one we will send to the remote server, and one we will receive from the remote server
+
+Then, here are the configurations changes that we'll need to make at our end to enable the connections.
+
+## Firewall or EC2 security group
+
+The main tilde.club IRC server needs to allow traffic from the remote server; this means that we need to allow traffic from the specific IP address to either port `6667` (for non-SSL connections) or port `6697` (for SSL connections).
+
+## charybdis ircd.conf file
+
+There needs to be [a `connect` section](https://github.com/tildeclub/tilde.club/blob/master/docs/ircserver.md#connect-section) in the `ircd.conf` file for each remote server. See [the documentation for our server setup](https://github.com/tildeclub/tilde.club/blob/master/docs/ircserver.md#connect-section) for full information about how this is configured.
