+# Hackceler8 2024 game rounds
+
+The game variations for the rounds of Hackceler8 2024, including
+
+* The sanity check round (round_0_test)
+* Day 1 (round_1 - round_3)
+* Day 2 (last chance playoffs, (round_4, round_5)
+* Day 3 (semifinals and finals, round_6 - round_8)
+
+For each round, the handout/ dir contains the files we handed out to players during the round. The server/ dir contains the code we ran on the server which had additional logic like the server-side boss code as well as debug tools we used (hitbox rendering, secret teleportation command, modded "cheat" client with frame-by-frame replays, challenge authors' solution scripts to the challs).

+# Hackceler8 2024 Game
+
+## Steps to run the game:
+
+1. Install prerequisites
+```
+cd hackceler8-2024-game
+python3 -m venv my_venv
+source my_venv/bin/activate
+pip3 install -r requirements.txt
+```
+
+2. Run server (optional but good for testing cheat detection/etc.)
+
+```
+cd hackceler8-2024-game
+source my_venv/bin/activate
+python3 server.py
+```
+
+3. Run client
+
+```
+cd hackceler8-2024-game
+source my_venv/bin/activate
+python3 client.py
+```
+
+If you want to run the client without a server, pass `--standalone` as an additional argument.
