+    NVIDIA NIM enables you to run powerful LLMs locally on your Windows machine using WSL2 (Windows Subsystem for Linux). 
+    This approach allows you to leverage your NVIDIA GPU for private, secure, and cost-effective AI inference without relying on cloud services. 
+    Perfect for development, testing, or production scenarios where data privacy or offline capabilities are required.
+    
+    Here is a step-by-step guide to setting up a local NVIDIA NIM model:
+    
+    1. Follow installation instructions from [NVIDIA Website](https://docs.nvidia.com/nim/wsl2/latest/getting-started.html)
+
+    2. Install the local model. For Llama 3.1-8b follow [instructions](https://build.nvidia.com/meta/llama-3_1-8b-instruct/deploy)
+
+    3. Configure your crewai local models:
+  
+    ```python Code
+    from crewai.llm import LLM
+
+    local_nvidia_nim_llm = LLM(
+        model="openai/meta/llama-3.1-8b-instruct", # it's an openai-api compatible model
+        base_url="http://localhost:8000/v1",
+        api_key="<your_api_key|any text if you have not configured it>", # api_key is required, but you can use any text
+    )
+
+    # Then you can use it in your crew:

+title: Apify Actors
+description: "`ApifyActorsTool` lets you call Apify Actors to provide your CrewAI workflows with web scraping, crawling, data extraction, and web automation capabilities."
+# hack to use custom Apify icon
+icon: "); -webkit-mask-image: url('https://upload.wikimedia.org/wikipedia/commons/a/ae/Apify.svg');/*"

+
+# `ApifyActorsTool`
+
+Integrate [Apify Actors](https://apify.com/actors) into your CrewAI workflows.
+
+## Description
+
+The `ApifyActorsTool` connects [Apify Actors](https://apify.com/actors), cloud-based programs for web scraping and automation, to your CrewAI workflows.
+Use any of the 4,000+ Actors on [Apify Store](https://apify.com/store) for use cases such as extracting data from social media, search engines, online maps, e-commerce sites, travel portals, or general websites.
+
+For details, see the [Apify CrewAI integration](https://docs.apify.com/platform/integrations/crewai) in Apify documentation.
+
+## Steps to get started
+
+<Steps>
+    <Step title="Install dependencies">
+        Install `crewai[tools]` and `langchain-apify` using pip: `pip install 'crewai[tools]' langchain-apify`.
+    </Step>
+    <Step title="Obtain an Apify API token">
+        Sign up to [Apify Console](https://console.apify.com/) and get your [Apify API token](https://console.apify.com/settings/integrations)..
+    </Step>
+    <Step title="Configure environment">
+        Set your Apify API token as the `APIFY_API_TOKEN` environment variable to enable the tool's functionality.
+    </Step>
+</Steps>
+
+## Usage example
+
+Use the `ApifyActorsTool` manually to run the [RAG Web Browser Actor](https://apify.com/apify/rag-web-browser) to perform a web search:
+
+```python
+from crewai_tools import ApifyActorsTool
+
+# Initialize the tool with an Apify Actor
+tool = ApifyActorsTool(actor_name="apify/rag-web-browser")
+
+# Run the tool with input parameters
+results = tool.run(run_input={"query": "What is CrewAI?", "maxResults": 5})
+
+# Process the results
+for result in results:
+    print(f"URL: {result['metadata']['url']}")
+    print(f"Content: {result.get('markdown', 'N/A')[:100]}...")
+```
+
+### Expected output
+
+Here is the output from running the code above:
+
+```text
+URL: https://www.example.com/crewai-intro
+Content: CrewAI is a framework for building AI-powered workflows...
+URL: https://docs.crewai.com/
+Content: Official documentation for CrewAI...
+```
+
+The `ApifyActorsTool` automatically fetches the Actor definition and input schema from Apify using the provided `actor_name` and then constructs the tool description and argument schema. This means you need to specify only a valid `actor_name`, and the tool handles the rest when used with agents—no need to specify the `run_input`. Here's how it works:
+
+```python
+from crewai import Agent
+from crewai_tools import ApifyActorsTool
+
+rag_browser = ApifyActorsTool(actor_name="apify/rag-web-browser")
+
+agent = Agent(
+    role="Research Analyst",
+    goal="Find and summarize information about specific topics",
+    backstory="You are an experienced researcher with attention to detail",
+    tools=[rag_browser],
+)
+```
+
+You can run other Actors from [Apify Store](https://apify.com/store) simply by changing the `actor_name` and, when using it manually, adjusting the `run_input` based on the Actor input schema.
+
+For an example of usage with agents, see the [CrewAI Actor template](https://apify.com/templates/python-crewai).
+
+## Configuration
+
+The `ApifyActorsTool` requires these inputs to work:
+
+- **`actor_name`**
+  The ID of the Apify Actor to run, e.g., `"apify/rag-web-browser"`. Browse all Actors on [Apify Store](https://apify.com/store).
+- **`run_input`**
+  A dictionary of input parameters for the Actor when running the tool manually.
+  - For example, for the `apify/rag-web-browser` Actor: `{"query": "search term", "maxResults": 5}`
+  - See the Actor's [input schema](https://apify.com/apify/rag-web-browser/input-schema) for the list of input parameters.
