+
+# Description
+Blazor & WASM in combination to get statistics from Spotify API for performing the song analysis. With separate microservices for auth, Spotify, user data tracking, and application, connected through gRPC with Polly. [git](https://git.dilig.net/nemanja.grkovic/NemAn) 
+
+## Tech stack
+For this project we used Blazor WASM (WebAssembly) on the frontend and .NET 6 on the backend, we used MongoDB for the database
+
+## Development environment

+
+# Setup
+
+Here we will show you how to set up project and run it in localhost.

+
+## Database setup
+Please follow the official tutorial on installing and running the latest Mongo database which can be found on this link:
+> https://docs.mongodb.com/manual/tutorial/install-mongodb-on-windows/
+
+## Project setup
+In order to run our project you need to clone it from [git](https://git.dilig.net/nemanja.grkovic/NemAn) first. Open terminal (cmd and powershell work as well) in folder that you want this project to be and run command 
+> git clone https://git.dilig.net/nemanja.grkovic/NemAn
+
+
+After cloning the project, it is necessary to set up git-flow for that folder for easier project organization, and you will do that by following the instructions - [Git-flow cheatsheet](http://danielkummer.github.io/git-flow-cheatsheet/)
+
+When you have finished the necessary setup, you can start the projects, the current alternative is to start each separately, docker soon.
