Be very cautious when entering mining world.
The hardware price is high, the difficulty is going up every month/day.
That's is only a few problem that you will encounter, there is a lot more will come.
If you are a gamer, and have an decent gpu/vga
then try mining with it first, see the result, learn to use the miner program, research the pool
research best coin to mine with what hardware.
If you knew about computer hardware & software it will be a great help.
After that calculate the ROI, with your funds
It's actually a bad time to enter mining world now.
Except you have many funds, do not ever enter with limited free funds or even get a loan.
