 # Project Happy Thoughts 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.
+This week's project is to use Express and MongoDB to build an API which includes both GET request endpoints to return data and POST endpoints to create data.
 
 ## 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?
+It was tricky to understand how the infrastructure was going to work. One thing that helped my to better understand how to connect the api and database with the old front end project was to create a workspace in vs code. The deploy process was difficult.
 
 ## 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.
