 - Do NOT talk to BLOOM as an entity, it's not a chatbot but a webpage/blog/article completion model.
 - For the best results: MIMIC a few sentences of a webpage similar to the content you want to generate.
 Start a paragraph as if YOU were writing a blog, webpage, math post, coding article and BLOOM will generate a coherent follow-up. Longer prompts usually give more interesting results.
+- Content: Please see our [content disclaimer](https://huggingface.co/spaces/bigscience/bloom-book) before using the model, as it may sometimes behave in unexpected ways.

 Options:
 - sampling: imaginative completions (may be not super accurate e.g. math/history)
 - greedy: accurate completions (may be more boring or have repetitions)
