First you need to know what is bitcoin before buying it and only invest the amount which you can afford to lose.
Then you need to buy bitcoins from exchange choose the best exchange like coinbase,but I always used to buy on localbitcoin.com because coinbase is not available in my country.
Then choose an wallet like Ledger Nano S or Electrum to keep it for future usage.
