 # Elemental on Command Line
 This is an elemental combination game written in C, with optional multi-player support.
 
+## Clients
+- [PenguinMod client](https://studio.penguinmod.com/?fps=200&clones=Infinity&offscreen&size=850x480#7218964246) for playing the game online with a fancy interface
+- [Discord client](https://discord.gg/DKZTWyWH3B) for playing the game publicly with other Discord members
+- [Web client](https://elem.dervland.net/) for a demo of the multiplayer version
+- [Original client](https://git.dervland.net/elemental/elemental-on-terminal/releases) for developers, administrators, and command line fans
+
 ## Single-player
 A single-player example pack is provided as an example in ``bin/combos.txt``. This can be customized by the user, although internal limitations require the combination string to be in alphabetical order.
 
 ## Multi-player
-To set up multi-player mode, create a directory ``../elem_data``.  Also, create separate directories for each user that plays.
-
-The game can now be played with the following syntax, inside your user directory:
-```sh
-cd ../your_user_dir
-../elemental-command-line/bin/elem your_username
-```
+To set up multi-player mode, use the guide with the [Web proxy](https://git.dervland.net/elemental/elemental-to-web).
