+### Launch a development server locally
+This outlines the steps required to run the Kedro-Sphinx-Theme locally on your machine, either with your kedro, kedro-viz or kedro-dataset. 
 
-## Overview
+Before launching a development server, you'd need to have [Python](https://www.python.org/)(>=3.9) installed. We strongly recommend setting up [conda](https://docs.conda.io/en/latest/) to manage your Python versions and virtual environments. You can visit Kedro's [guide to installing conda](https://docs.kedro.org/en/latest/get_started/install.html#create-a-virtual-environment-for-your-kedro-project) for more information.
 
-Add a longer description here.
+#### Steps
+
+1. **Clone the Kedro-Sphinx-Theme Repository**
+First, you need to get the Kedro-Sphinx-Theme directory on your local machine. Navigate to the directory where you have cloned the repository:
+
+```bash
+cd kedro-sphinx-theme
+```
+
+Get the location of your local repository and copy the output path for later use:
+
+```bash
+pwd
+```
+
+2. **Setup the docs build requirement in your repository**
+Navigate to the directory where you want to run the documentation locally. This can be within your Kedro, Kedro-Viz, or Kedro-Dataset project:
+
+```bash
+cd path/to/your/kedro/or/kedro-viz/or/kedro-dataset
+```
+
+Ensure your Python environment is active and ready.Then navigate to the package directory
+
+```bash
+cd package
+```
+
+Install the documentation dependencies
+
+```bash
+pip install ".[docs]"
+```
+
+Use the path you copied earlier to install the kedro-sphinx-theme package
+
+```bash
+pip install -e "path/to/kedro-sphinx-theme"
+```
+
+After installing all the requirements, build the documentation from the root of the repository
+
+```bash
+cd to/your/root
+```
+
+```bash
+sphinx-build -WETa --keep-going -j auto -D language=en -b html -d docs/build/doctrees docs/source docs/build
+```
+
+3. **Start a Local HTTP Server**
+Finally, navigate to the docs/build directory and start a local HTTP server to view the documentation:
+
+Navigate to the docs/build directory
+
+```bash
+cd docs/build
+```
+
+Start the server
+
+```bash
+python -m http.server
+```
+
+Once everything is successfully built and run, you can open the documentation development locally through `http://localhost:your-port`
