Where newbie is expected to find info about using Ethereum on Linux?

Hi all!

Why information on https://ethereum.org is so incomplete? I want to start to use Ethereum, so I need at least 1. get ETH, 2. be able to transfer it. However on https://ethereum.org in main menus in "Get ETH" I could not find info on mining and as for transactions only relevant is Wallets, says proudly apps for all platforms, but I've found only one of several listed has desktop option, also page lacks e.g. geth application. Geth docs says it needs some clef to send ETH, but downloads links do not have clef, only geth. Very confusing IMO.

Where am I (newbie) expected to find info? Asking every time on boards/googling? TIA
