 Follow these instructions to set up your development environment, which you need to do before you start contributing code to this project.
 
+There are two ways to install the project locally:
+
+Manual Installation is great if you're comfortable managing dependencies like Node.js and MongoDB directly on your machine. It's more hands-on and gives you finer control, which can be helpful for debugging or learning how each part works.
+
+Docker Installation is ideal if you want a faster setup with all dependencies (Node, MongoDB, etc.) isolated in containers. This avoids version conflicts and works consistently across environments especially helpful if you're new to backend setup or don't want to alter your local setup.

 ## Manual Installation
 
 _Note_: The installation steps assume you are using a Unix-like shell. If you are using Windows, you will need to use `copy` instead of `cp`.
