+
+A docker container for the Out Of Your Element ( OOYE ) Matrix-to-Discord bridge. OOYE makes it
+_super_ easy to bridge your Discord server to matrix, and this container makes it easy to deploy.
+
+> **Under Construction 🚧:** The instructions are under construction.
+
+## Usage
+
+### Create Discord Bot
+
+The first step is to create a Discord bot that can be invited to the discord servers that you want
+to bridge to matrix.
+
+1. Go to the [Discord Developer Applications page](https://discord.com/developers/applications).
+2. Click "New Application".
+3. Give it a name like "My Bridge Bot" and click "Create".
+4. Go to the "Bot" tab in the left sidebar.
+5. Scroll down and click the "Reset Token" button.
+6. Confirm with "Yes, do it!" button.
+7. There will now be a token displayed.
+8. Click "Copy" below the token, and save that for future reference.
+
+### Setup OOYE
+
+Now we can run our OOYE bridge.
+
+1. Run the following command on your server **twice**, to generate two random 64 character hex keys,
+  and save the keys for future reference.
+  ```
+  dd if=/dev/urandom bs=32 count=1 2> /dev/null | basenc --base16 | dd conv=lcase 2> /dev/null
+  ```
+2. Create a `docker-compose.yml` like the one below, but with your server info and tokens substituted
+  in the `environment` section.
+  ```yaml
+services:
+  ooye:
+    image: ghcr.io/katharostech/ooye:master
+    environment:
+      SERVER_NAME: your.server.name
+      SERVER_ORIGIN: https://your.server.name
+      ADMIN_INVITE: "@your_admin_user:some.matrix.server.that.could.be.your.server.name.or.not"
+      URL: http://address_of_ooye_from_your.server.name:6693
+      HS_TOKEN: your_first_random_token
+      AS_TOKEN: your_second_random_token
+      DISCORD_TOKEN: your_discord_bot_token
+    ports:
+      - 6693:6693
+    volumes:
+      - ooye-data:/app/db
+
+volumes:
+  ooye-data:
+  ```
