Welcome to OSR.
This section of the forum and the tutorials sections has literally dozens of very good guides that answer this very question.
New guys who ask these kinds of questions straight away without looking around first earn a bad reputation. Some even get banned for this.
So take a good look around. The information is widely available. If something is missing, then ask away. But the instructions and tools you are looking for are very easy to find here.
Don't get banned because you didn't take an extra few minutes before posting something.
