+# DirectorySearchTool
+
+## Description
+This tool is designed to perform a semantic search for queries within the content of a specified directory. Utilizing the RAG (Retrieval-Augmented Generation) methodology, it offers a powerful means to semantically navigate through the files of a given directory. The tool can be dynamically set to search any directory specified at runtime or can be pre-configured to search within a specific directory upon initialization.
+
+## Installation
+To start using the DirectorySearchTool, you need to install the crewai_tools package. Execute the following command in your terminal:
+
+```shell
+pip install 'crewai[tools]'
+```
+
+## Example
+The following examples demonstrate how to initialize the DirectorySearchTool for different use cases and how to perform a search:
+
+```python
+from crewai_tools import DirectorySearchTool
+
+# To enable searching within any specified directory at runtime
+tool = DirectorySearchTool()
+
+# Alternatively, to restrict searches to a specific directory
+tool = DirectorySearchTool(directory='/path/to/directory')
+```
+
+## Arguments
+- `directory` : This string argument specifies the directory within which to search. It is mandatory if the tool has not been initialized with a directory; otherwise, the tool will only search within the initialized directory.
