+![Code Quality](https://git.0day.agency/wirehack7/novelai-bot/actions/workflows/check-code_quality.yaml/badge.svg)
+![Safety Check](https://git.0day.agency/wirehack7/novelai-bot/actions/workflows/check-safety.yaml/badge.svg)
+![Release](https://git.0day.agency/wirehack7/novelai-bot/actions/workflows/release.yaml/badge.svg)
+
+Simple bot which registers a command to generate images via the NovelAI API.
+
+## Usage
+
+Just enter `/generate` in the desired channel.
+
+```text
+/generate 
+    *prompt: string
+    undesired_prompt: string
+    orientation: landscape or portrait
+    seed: integer
+```
+
+`*: required`
+
+## Run
+
+You might create environvent vars:
+
+- **NOVELAI_API_TOKEN**: your NovelAI user API key
+- **DISCORD_BOT_TOKEN**: token of your Discord bot
+- **DISCORD_CHANNEL_ID**: ID of the channel to enable this bot
+
+Don't forget to install the requirements in [requirements.txt](src/requirements.txt)
+
+## Docker Compose
+
+Or simply run it via **docker-compose**:
+
+```yaml
+services:
+  bot:
+    restart: unless-stopped
+    image: git.0day.agency/wirehack7/novelai-bot:latest
+    environment:
+      - NOVELAI_API_TOKEN=
+      - DISCORD_BOT_TOKEN=
+      - DISCORD_CHANNEL_ID=
+networks: {}
+```
+
+## Notes
+
+To create a Discord bot go to [Discord Developers](https://discord.com/developers/).
+You should make the bot private.
