 yes
 
+## things i made arpchat do
+
+you can send messages tens of thousands of characters long because i implemented a (naive) generalizable transport protocol on top of arp. there's also a bit of compression.
+
+if you wanted, you could probably split off the networking part of this and use it instead of udp. please don't do this.
+
+not only are join and leave notifications a thing, i built an entire presence discovery system to see a list of other online users. ironically, this serves a similar purpose to arp itself.
+
+i'm planning on experimenting with and adding settings for different arp packet types, since some routers might filter out the malformed ip packets i'm currently using.

 ## running
 
 if you actually want to install this for some reason, you can get it from [the releases page](https://github.com/kognise/arpchat/releases/latest).
 
 on windows, you probably need [npcap](https://npcap.com/#download). make sure you check "Install Npcap in WinPcap API-compatible Mode" in the installer!
 
+![interface selector](https://doggo.ninja/tvFJ2A.png)
+
 then just run the binary in a terminal. you know it's working properly if you can see your own messages when you send them. if you *can't* see your messages, try selecting a different interface!
 
 have any issues? that really sucks. you can make an issue if it pleases you.
