problem to find a library

Hello I’m in first and I discover arduino programming this year and I have to do a project. My problem is that I made a code from an old code and the library below: <TSRobuno.h>
and I searched on the internet but I did not find it so it would be to know if anyone to the solution to find it. thank you very much in advance

There are TWO hits on google for TSRobuno, neither of which has anything to do with Arduino.

So this is something that was never posted on the internet; could this have been a library you received direct from the author or something?

in the finale it's good I managed to find I had to launch ardublock and the library worked

Where's the tutorial?
