 # Project Express API
 
-Replace this readme with your own information about your project.
+Week 17th project. Build an API with Express.js. And deploy on Render (first time). 
 
-Start by briefly describing the assignment in a sentence or two. Keep it short and to the point.
+Using REST (Http method + path) and the results displayed must be: an array, a single register, or a failure (incomplete 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 my first time on back end and I feel very confortable on that side (server, etc). If I will have more time I would like to style and create a page to show the results properly, but the final project is close! 
 
 ## 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.
