+# Playing
+
+Get yourself Java 8, or operate in the environment where Java 8 is available. Good launchers generally allow you to pick and test the Java installation.
+
+Get yourself a CurseForge -compatible launcher:
+- Curse Forge (obviously)
+- Prism Launcher
+- Multi MC
+- some other launchers exist, this is not a wiki
+
+Then, import the modpack at:
+```
+https://git.dzuchun.ing/api/packages/dzu/generic/nomisuffory/1.0.0/NomiSuffory.zip
+```
+
+If you want to play with yourself (shush), you are ok to go.
+
+If you want to join the server I host:
+- contact me somehow (if you don't know how, then you probably should not)
+- prepare to join `nomi.dzuchun.ing`
+- for the first time, you'll need to join while I am at the server
+
+If you want to host a server on your own, here is simplified docker compose file:
+```compose
+  nomifactory:
+    image: git.dzuchun.ing/dzu/nomisuffory:main
+    ports:
+      - 25565
+    volumes:
+      - ./eula.txt:/srv/eula.txt:ro
+      - ./world:/srv/world:rw
+    environment:
+      MC_MEMORY: 4G
+```
+
+here,
+- `MC_MEMORY` determined the JVM heap size (2G by default)
+- `eula.txt` is a file you must create and put `eula=true` into it, to confirm you've accepted the EULA
