Where do you live? Your options on getting your local cash into any crypto-currency are directed somewhat by where you live.
First step, open a wallet on an exchange that (1) deals in your local currency, and ideally (2) deals in the crypto-currency you want, although this isn't required.
Second step, buy your desired crypto-currency, or if you can't, because it's a more obscure option, buy some Bitcoin or Litecoin as it can easily be traded for any other currency.
Third step, if you've bought Bitcoin/Litecoin but really want a different currency, you now need to open a wallet that deals in your desired/destination currency.
Forth step, trade your Bitcoin/Litecoin for the destination/desired currency.
Some resources for you:
Coinbase is a great option to get your local currency into Bitcoin/Ethereum/Litecoin, but it's not available everywhere.
Good luck to you!
