+
+---
+
+### First stage
+
+- Server starts
+- It accepts two params, ./ircserv <port> <password>
+- The server accepts one user, user can send messages and we can see from server
+- Only 1 poll()
+
+### Second stage
+
+- Server can handle multiple clients simultaneously
+
+### Third stage
+
+- Client has nickname and username
+- Client needs password for authenticate
+- Client can be regular user or operator (admin)
+
+### Fourth stage
+
+- Client can create/connect to channels
+- Client can send message inside channel (only people inside this channel can read)
+
+*It will continue...*
