I don't know which tool

Don’t worry. We’ll find the right folder just by looking, with no prior knowledge needed.

Step 1: Look for an index.html

Open the folder you were given and check whether it contains an index.html file right inside it.

• Yes → that’s your folder, upload it. (A ready-made website)
• No, but there’s a dist, build, or out sub-folder → open it: if it contains an index.html, that’s the one. Upload that sub-folder.
• No, and none of those folders → the site hasn’t been built yet. Go to Step 2.

Step 2: Read the package.json

If there’s a package.json file, open it with any text editor (Notepad, TextEdit). Find the "scripts" section:

"scripts": {
  "build": "vite build"
}

The word after build tells you the tool, and therefore the output folder:

If you see…	Tool	Folder it makes
vite build	Vite	dist
react-scripts build	Create React App	build
next build	Next.js	out (with static export)
astro build	Astro	dist

Then follow the matching guide in the left menu. In every case, the command is:

npm install
npm run build

Step 3: Just ask (the magic sentence)

If someone built the site for you, send them exactly this:

“Could you give me the build folder ready to host (the one with index.html right inside it, usually dist, build, or out), not the source code? I’m hosting it myself on Bailey.”

Anyone technical will get it on the first read.

When all else fails

Just drop what you have into Bailey and see. If an index.html is missing at the top level, Bailey will tell you. It’s never a big deal; nothing breaks by trying.
