+# Summarize topic
+
+Generate a short summary of the last 100 messages in the provided topic URL.
+
+### API Keys
+
+For testing you need access token from
+https://huggingface.co/settings/tokens (or set the correct env
+variable with the access token if using a different model)
+
+In `~/.zuliprc` add a section named `litellm` and set the api key for
+the model you are trying to use.  For example:
+
+```
+[litellm]
+HUGGINGFACE_API_KEY=YOUR_API_KEY
+```
+
+### Setup
+
+```bash
+$ pip install -r zulip/integrations/litellm/requirements.txt
+```
+
+Just run `zulip/integrations/litellm/summarize-topic` to generate
+sample summary.
+
+```bash
+$ zulip/integrations/litellm/summarize-topic --help
+usage: summarize-topic [-h] [--url URL] [--model MODEL]
+
+options:
+  -h, --help     show this help message and exit
+  --url URL      The URL to fetch content from
+  --model MODEL  The model name to use for summarization
+```
