+## Setting Up Chart Testing Lint with Pre-commit Hook
+#### Why Chart Testing Lint?
+When working with Helm charts, it's important to ensure that they meet best practices, are free from errors, and follow the defined guidelines. **Chart Testing (ct) Lint** is a tool designed to automate this process by linting your Helm charts before committing them to the repository. It helps to:
+- Catch errors early.
+- Enforce best practices in chart development.
+- Automatically validate changes to Helm charts during pull requests or commits.
+
+
+This guide will show you how to integrate `chart-testing` linting into your pre-commit hooks to automatically lint charts before committing them. It also allows you to manually trigger linting when needed.
+
+#### Prerequisites
+Before setting up the pre-commit hook, make sure you have the following dependencies installed:
+
+##### 1. Install `chart-testing`
+`chart-testing` is a command-line tool used to lint and validate Helm charts. It can be installed using **Homebrew** on macOS.
+
+To install `chart-testing`, run the following command:
+
+```bash
+brew install chart-testing
+```
+##### 2. Install `pre-commit`
+To install the pre-commit tool, run:
+```bash
+pip install pre-commit
+```
+#### Setting Up Pre-commit Hook for Chart Testing Lint
+##### 1. Install the Pre-commit Hook
+Once the dependencies are installed, navigate to your repository and run the following command to install the pre-commit hook:
+```bash
+pre-commit install
+```
+This will set up the pre-commit hook in the .git/hooks directory of your repository.
+##### 2. Manually Trigger the Linting Process
+If you need to manually trigger the linting of charts at any time, navigate to the root of your repository and run:
+```bash
+ct lint --all --check-version-increment=false --use-helmignore
+```
