Your project
Writing a prompt
You do not need a special format. You need a sentence that says what to build and how someone uses it. The first prompt sets the project. Later prompts change it.
What to include
Three things are enough for a first version.
- What it is. A booking page, a shop, a quiz, a runner.
- What is on it. Services and prices, a menu, three lives, a score.
- What the person does. Request a time, pay at checkout, tap to jump, answer a question.
A prompt that builds a page
“A page for a bakery. The menu with prices, a short note about pickup, photos, and a payment checkout.”
That tells Build3 the business, the content, and the action. “Make a beautiful modern website” does not. You can still ask for a calmer layout later, once the menu is on the page.
A prompt that builds a game
“A quiz about world capitals. Ten questions, four choices each, the score at the end.”
Lead with how it plays. A theme can be the second sentence. If you ask for five levels, a shop, and a story before the first level is playable, the first version is harder to test.
A prompt that changes something
Name the part and the problem. “The prices are too small on a phone.” “Add Saturday hours under the booking form.” “The jump should be higher.”
One change per message is easier to check. If you want three things, you can still put them in one message, as a short list, so they land together.
What to leave for later
Your own domain, analytics, and a database are unlocks in the project. You do not have to mention them in the first prompt for a simple page or a simple game.
Do not paste passwords, secret keys, or card numbers into the chat. A payment secret goes in the Secrets tab.
