+# Robotnik - A Basic LLM Capable IRC Bot.
+
+This is an IRC bot that.  The name is based on a fictional video game villain.
+Currently it supports any LLM that uses the OpenAI style of interface.  They
+can be selected via command line options, environment variables, or via a configuration
+file.  There is a [configuration file](config.toml) that *should* contain all available options
+currently.
+
+## Some supported but ~~possibly~~ *mostly* untested LLMs:
+
+| Name       | Model             | Base URL                                  | Tested  |
+|------------|-------------------|-------------------------------------------|---------|
+| OpenAI     | gpt-5             | https://api.openai.com/v1                 | no      |
+| Deepseek   | deepseek-chat     | https://api.deepseek.com/v1               | yes     |
+| Anthropic  | claude-sonnet-4-0 | https://api.anthropic.com/v1              | no      |
+| Gemini     | gemini-2.5-turbo  | https://generativelanguage.googleapis.com | no      |
+| OpenRouter | some-model        | https://api.openrouter.ai/v1              | no      |
+
+## Further reading...
+
+There should be a man page that might be useful.  Otherwise the -h/--help
+switch should hopefully suffice.
