Explain Equity in a Startup Offer to a First-Time Recipient

The offer letter says you get 10,000 options with a four-year vest and a one-year cliff, and you have no idea whether that is generous or nothing. This explains the type of equity, the vesting and cliff, and what the numbers mean at the company's stage, so you can value the offer before you accept or decline it.
