 - **Backstory**: A narrative that provides depth to the agent's character. This could include previous experience, motivations, or anything that adds context to their role.
 - **Tools**: The abilities or methods the agent uses to complete tasks. This could be as simple as a 'search' function or as complex as a custom-built analysis tool.
 
-# Customizing an Agent
+# Understanding Tools in CrewAI
+
+Tools in CrewAI are functions that empower agents to interact with the world around them. These can range from generic utilities like a search function to more complex ones like integrating with an external API. The integration with LangChain allows you to utilize a suite of ready-to-use tools such as [Google Serper](https://python.langchain.com/docs/integrations/tools/google_serper), which enables agents to perform web searches and gather data.
+
+# Customizing Agents and Tools
 
 You can customize an agent by passing parameters when creating an instance. Each parameter tweaks how the agent behaves and interacts within the crew.
 
+Customizing an agent's tools is particularly important. Tools define what an agent can do and how it interacts with tasks. For instance, if a task requires data analysis, assigning an agent with data-related tools would be optimal.
+
+When initializing your agents, you can equip them with a set of tools that enable them to perform their roles more effectively:
+
 ```python
 from crewai import Agent
+from langchain.agents import Tool
+from langchain.utilities import GoogleSerperAPIWrapper
 
-# Customize an agent with a detailed backstory and specialized tools
+# Initialize SerpAPI tool with your API key
+os.environ["OPENAI_API_KEY"] = ""
+
+# Create tool to be used by agent
+serper_tool = Tool(
+  name="Intermediate Answer",
+  func=search.run,
+  description="useful for when you need to ask with search",
+)
+
+# Create an agent and assign the search tool
 agent = Agent(
-  role='Content Creator',
-  goal='Generate engaging articles',
-  backstory='A seasoned writer with a passion for tech and storytelling.',
-  tools=['word_processor', 'plagiarism_checker']
+  role='Research Analyst',
+  goal='Provide up-to-date market analysis',
+  backstory='An expert analyst with a keen eye for market trends.',
+  tools=[serper_tool]
 )
 ```

 ## Delegation and Autonomy
 
-One of the most powerful aspects of CrewAI agents is their ability to delegate tasks to one another. By customizing which tasks an agent can delegate and to whom, you can create a self-organizing system that adapts to the workload efficiently.
+One of the most powerful aspects of CrewAI agents is their ability to delegate tasks to one another. Each agent by default can delegate work or ask question to anyone in the crew, but you can disable that by setting `allow_delegation` to `false`, this is particularly useful for straightforward agents that should execute their tasks in isolation.
+
+```python
+agent = Agent(
+  role='Content Writer',
+  goal='Write the most amazing content related to market trends an business.',
+  backstory='An expert writer with many years of experience in market trends, stocks and all business related things.',
+  allow_delegation=False
+)
+```
