Please help with web wallet!

  • Hello, for some reason my local wallet doesn't work and my computer can't handle to download the entire blockchain.
    So I will use web wallet instead.

    But can someone please show me how to start plotting and mining only using web wallet?
    I cannot find any explanations on the entire internet.

    All the explanations always assume you are using local wallet.
    So how can I mine and plot using web wallet?

    Can someone explain please, I really want to get started.
