A Worldcoin wallet is as simple as a single pairing of a Worldcoin address with its corresponding Worldcoin private key. Such a wallet has been generated for you in your web browser and is displayed above.
To safeguard this wallet you must print or otherwise record the Worldcoin address and private key. It is important to make a backup copy of the private key and store it in a safe location. This site does not have knowledge of your private key. If you are familiar with PGP you can download this all-in-one HTML page and check that you have an authentic version from the author of this site by matching the SHA256 hash of this HTML with the SHA256 hash available in the signed version history document linked on the footer of this site. If you leave/refresh the site or press the "Generate New Address" button then a new private key will be generated and the previously displayed private key will not be retrievable. Your Worldcoin private key should be kept a secret. Whomever you share the private key with has access to spend all the worldcoins associated with that address. If you print your wallet then store it in a zip lock bag to keep it safe from water. Treat a paper wallet like cash.
Add funds to this wallet by instructing others to send worldcoins to your worldcoin address.
Check your balance by going to Worldcoin Explorer and entering your Worldcoin address.
Spend your worldcoins by downloading the Worldcoin core wallet and importing your private key. Keep in mind when you import your single key to the worldcoin wallet and spend funds your key will be bundled with other private keys in the wallet. When you perform a transaction your change will be sent to another worldcoin address within the client wallet. You must then backup the client wallet and keep it safe as your remaining worldcoins will be stored there. Satoshi advised that one should never delete a wallet.

Worldcoin v0.6+ stores public keys in compressed format. The client now also supports import and export of private keys with importprivkey/dumpprivkey. The format of the exported private key is determined by whether the address was generated in an old or new wallet.
