+## Command Line Interface
+
+You can accomplish multi-step agentic tasks using two commands: `smolagent` and `webagent`. `smolagent` is a more generalist command to run a multi-step CodeAgent that can be equipped with various tools, meanwhile `webagent` is an agent equipped with web browsing tools using [helium](https://github.com/helium).
+
+**Web Browser in CLI**
+
+`webagent` allows users to automate web browsing tasks. It uses the Helium library to interact with web pages and uses defined tools to browse the web. Read more about it [here](https://github.com/huggingface/smolagents/blob/main/src/smolagents/vision_web_browser.py).
+
+Run the following command to get started:
+```bash
+webagent {YOUR_PROMPT_HERE} --model "LiteLLMModel" --model-id "gpt-4o"
+```
+
+A good example command to get started is `$ webagent --prompt "go to xyz.com/women, get to sale section, click the first clothing item you see. Get the product details, and the price, return them. note that I'm shopping from France"`. We redacted the website here, modify it with website of your choice.
+
+**Tool Calling Agent in CLI**
+
+You can run `smolagent` command to run a multi-step agent with [tools](https://huggingface.co/docs/smolagents/en/reference/tools). It uses web search tool by default.
+You can easily get started with `$ smolagent {YOUR_PROMPT_HERE}`. A more custom version of this one-liner is following, see more details [here](https://github.com/huggingface/smolagents/blob/main/src/smolagents/cli.py).
+
+```bash
+smolagent {YOUR_PROMPT_HERE} --model-type "HfApiModel" --model-id "Qwen/Qwen2.5-Coder-32B-Instruct" --imports "pandas numpy" --tools "web_search translation"
+```
+
+A good example command to get started is `$ smolagent "Plan a trip to Tokyo, Kyoto and Osaka between Mar 28 and Apr 7. Allocate time according to number of public attraction in each, and optimize for distance and travel time. Bring all the public transportation options."`. 
+
 ## Code agents?
 
 In our `CodeAgent`,  the LLM engine writes its actions in code. This approach is demonstrated to work better than the current industry practice of letting the LLM output a dictionary of the tools it wants to calls: [uses 30% fewer steps](https://huggingface.co/papers/2402.01030) (thus 30% fewer LLM calls)
