+## School-library
+Imagine that you are the librarian of OOP University, and you need a tool to record what books are in the library and who borrows them. This app that I created will make your library the best organized one. 
+This app allows you to:
+- Add new students or teachers.
+- Add new books.
+- Save records of who borrowed a given book and when.
