 Register an account at https://nft.storage and create a new API key.
 
-Open `store.html`/`storeBlob.html`/`storeCar.html`/`storeDirectory.html` and replace `API_KEY` in the code with your key.

+# CAR upload demo - nft.storage
+
+A demo using ipfs-car in the browser to create a CAR file and pre-calculate the CID for an asset then storing it on nft.storage and confirming that it uses the exact same CID for the asset.
+
+## Getting started
+
+```console.
+npm install
+npm run dev
+
+# or
+yarn
+yarn dev
+```
+
+Then visit `http://localhost:3000?key=<your nft.upload API KEY here>`
