-# project-delta
-Tracking Growth
+# Project Delta
+Project Delta is an attempt to provide Pesto’s instructors visibility into how effectively the student body is learning the curriculum.
+
+- [Students Portal](https://deltapesto.herokuapp.com/)
+- [Instructors Portal](https://deltapesto-instructors.herokuapp.com/)
+- [Api Portal](https://deltapesto-api.herokuapp.com/)
+
+## Description
+Project Delta enables tracking:
+1. How confident students are that they have mastered topics covered in the lectures
+2. Student's performance in exercises
+
+… and presenting instructors with visualizations that will allow easy identification of:
+1. Struggling students
+2. Insufficiently-explained topics
+3. Unreasonably difficult exercises
+
+For more details, refer [Delta - Project Spec](__specs__/Delta-ProjectSpec.pdf)
+
+## Getting started
+
+```shell
+yarn install
+```
+
+To start app, follow below links
