Function fitting neural network

Hi everyone,
I am a beginner in using Julia and I want to ask how to use neural network in Julia.
To be more specific, I have a target matrix 8x5000 and an input matrix 300x5000 and I want to find coefficients for fitting function. In matlab I can do it using fitnet command, but it takes too much time to solve the model in matlab, so I want to do it in Julia. Can You provide some hints how to do it?
Thanks in advance.
