+
+## Docker
+
+The recommended method for Linux and MacOS users is to use a prebuilt Docker image.
+Windows may work but is not yet officially supported: use the binary instead.
+
+### Installing Docker
+
+First, install Docker.
+Instructions will be different depending on your OS, but it is recommended to follow [the method outlined in the official Docker website.](https://docs.docker.com/get-docker/)
+
+If you are using Linux, make sure to perform any post-install necessary afterwards.
+[The official Docker website has optional post-install instructions.](https://docs.docker.com/engine/install/linux-postinstall/)
+
+### Docker Image
+
+The image expects a volume mounted at `/kinode-home`.
+This volume may be empty or may contain another Kinode's data.
+It will be used as the home directory of your Kinode.
+Each volume is unique to each Kinode.
+If you want to run multiple Kinodes, create multiple volumes.
+
+The image includes EXPOSE directives for TCP port `8080` and TCP port `9000`.
+Port `8080` is used for serving the Kinode web dashboard over HTTP, and it may be mapped to a different port on the host. 
+Port `9000` is optional and is only required for a direct node.
+
+If you are running a direct node, you **must** map port `9000` to the same port on the host and on your router.
+Otherwise, your Kinode will not be able to connect to the rest of the network as connection info is written to the chain, and this information is based on the view from inside the Docker container.
+
+Run the following command to create a volume:
+```bash
+docker volume create kinode-volume
+```
+
+Then run the following command to create the container.
+Replace `kinode-volume` with the name of your volume, and `my-kinode` with a unique name.
+To map the port to a different port (for example, `80` or `6969`), change `8080:8080` to `PORT:8080`, where `PORT` is the post on the host machine.
+```bash
+docker run -d -p 127.0.0.1:8080:8080 -it --name my-kinode \
+    --mount type=volume,source=kinode-volume,destination=/kinode-home \
+    0xlynett/kinode
+```
+
+Check the status of your Docker processes with `docker ps`.
+To start and stop the container, use `docker start my-kinode` or `docker stop my-kinode`.
+To remove the container, run `docker remove my-kinode`.
+(replace `my-kinode` with the name of your container)
+
+As long as the volume is not deleted, your data remains intact upon removal or stop.
+If you need further help with Docker, [access the official Docker documentation here](https://docs.docker.com/manuals/).

 ## Download Binary
 
-The recommended method for most users is to use a precompiled binary.
-If you want to make edits to the Kinode core software, see [Build From Source](#build-from-source).
+If you do not have Docker, you can download a precompiled binary instead.
 
 First, get the software itself by downloading a [precompiled release binary](https://github.com/kinode-dao/kinode/releases).
 Choose the correct binary for your particular computer architecture and OS.
