Disclaimer
I am just posting the links I found on the internet. I am not sure how come that TLauncher provides Minecraft for free, but it does and it works.
If you think this is not legal, or I should not use it, please contact me via form, or send me an email to gaming@bymatej.com.
I am in no way affiliated with TLauncher and/or Mojang/Minecraft.
Thanks!

Select the latest Minecraft version from the dropdown. I used 1.14.4. Click the Install button and the TLauncher will download your Minecraft game.
Check the Accounts checkbox and add your account you created in the first step.
After the game is installed, and the account is added, you will have the Enter the game button ready and it should look like this:

Playing the game
You can play in Singleplayer or in Multiplayer.
If you play in Singleplayer mode, you can create your own world and you can have fun either in Creative mode or in Survival mode.
You can play with your friends either in LAN (your local network), or Online (if you have a set up a server).
