 # Project Mongo API
 
-Replace this readme with your own information about your project.
-
-Start by briefly describing the assignment in a sentence or two. Keep it short and to the point.
+The project demonstrates working with MongoDB/Mongoose, implementing RESTful principles, and building a functional API with filtering capabilities.
 
 ## The problem
 
-Describe how you approached to problem, and what tools and techniques you used to solve it. How did you plan? What technologies did you use? If you had more time, what would be next?
+I set up a MongoDB database with environment variables for secure access and added database seeding to populate MongoDB with The Sims npcs data. Had to troubleshoot MongoDB connection issues but eventually got it to work.
+I created API endpoints to:
+Get all NPCs with filtering options
+Find specific NPCs by ID
+View API documentation
+
+I also implemented filtering by game version, life stage, and category
 
 ## View it live
 
-Every project should be deployed somewhere. Be sure to include the link to the deployed project so that the viewer can click around and see what it's all about.
