Creating Dashboard with Company KPIs

Hello Community,

im completely new in this thing called “Grafana”
So i have a few questions.

I need to Create a Dashboard with Grafana , i get all the KPI from MSSQL-Server

Would you recommend using/creating it on Windows?
Which Plugins should i use?
Do you recommend a good tutorial for beginners?
Are there any good tips for beginners?

Hope you guys can help me.
