+This is a Kata which aims at developing a Node API for creating a personal Movie Database using Test Driven Development[TDD] approach
+
+## Requirements
+- good understanding of JavaScript
+- basic knowledge of server/client request/response
+- basic understanding of HTTP
+- basic understanding of GIT
+
+## Development using
+- Node.js
+- TDD approach
+- [Postman](https://www.getpostman.com/) - API development environment
+- [Robo 3T](https://robomongo.org/) - a free lightweight GUI for MongoDB enthusiasts
+
+
+## User Story 1
+1. As a User I want to insert movie information to create my own movie database.
+
+### Acceptance Criteria
+- The movie to be inserted must have title and description
+- User cannot enter the same movie name again i.e duplicates must be tracked based on the title of the movie
+- The user must send the data to the API in JSON format
+
+## User Story 2
+Coming soon...
