 ## Docker
-- Docker is supported and tested, you can find the image and instructions [here](https://github.com/Kizaing/KavitaDocker). 
+Running your Kavita server in docker is super easy! Barely an inconvenience. You can run it with this command: 
+
+```
+docker run --name kavita -p 5000:5000 \
+-v /your/manga/directory:/manga \
+-v /kavita/data/directory:/kavita/data \
+--restart unless-stopped \
+-d kizaing/kavita:latest
+```
+
+You can also run it via the docker-compose file:
+
+```
+version: '3.9'
+services:
+    kavita:
+        image: kizaing/kavita:latest
+        volumes:
+            - ./manga:/manga
+            - ./data:/kavita/data
+        ports:
+            - "5000:5000"
+        restart: unless-stopped
+```
+
+Note: Kavita is under heavy development and is being updated all the time, so the tag for current builds is :nightly. The :latest tag will be the latest stable release. There is also the :alpine tag if you want a smaller image, but it is only available for x64 systems.
