+# Formatting of socket
+
+IRC is quite a hassle to understand, so the first thing to know about the protocol is the **socket** and **server/client**.
+
+TLDR:
+```
+↗️ PRIVMSG target :content
+🔀 :nick!ident@host PRIVMSG target :content
+^ Replace nick, ident, host, & target with the respective values described.
+↗️ COMMAND arg :content
+↙️ :server RPL nick data :content
+^ Replace nick with the nickname of the current connection.
+```
+
+
+
+> [!CAUTION]
+> If the command has content, the colon MUST be included, and is at the beginning of the content, not the end of the command/args.
+> ```
+> ↗️ COMMAND: content
+> ↙️ :server 421 nick COMMAND: :Unknown command
+> ^ Replace nick with the nickname of the current connection.
+> ```
+> For more info on 421, see [Not Found](notfound.md)
