2.8 Metamask will open. This is your last chance to reject the transaction. If you are ready to send it to the blockchain click Confirm.

2.9 The hash will appear quickly. But it can take up to 15 seconds for the contract address to display. Once it displays click copy to copy it to your clipboard.
(Save the contract address in a safe place you will need it in sections 3 and 4.)

3.1 Click on "Interact With" from the left menu.
3.2 Copy and paste the contract address. (From deploy step 2.9)
3.3 Copy and paste the contract's ABI interface to interact with a contract. (From Remix step 1.7)
3.4 Click Next to interact with a contract.

3.5 Click on Connect in the upper right corner.
(If you are already connected your address and tFuel balance will be display.)
3.6 Select the function you would like to use with the contract.
3.7 The interface will appear.
3.8 Click interact to read or write to the contract. If the function is a read function click interact and the results will display, no more action is needed. If the function is a write function enter the inputs if needed and click interact.

3.9 Only if it is not a read function. Metamask will open. This is your last chance to reject the transaction. If you are ready to send it to the blockchain click Confirm.

3.10 If it is a write function the transaction hash will appear below the interact button. If it is a call function no hash will display. (You can click View on Thetascan.io to see the transaction hash details on the block explorer in a new window.)

4.1 Click on "Dapp Builder" from the left menu.
4.2 Copy and paste in the contract address (From deploy step 2.9)
4.3 Copy and paste in the contract ABI. (From Remix step 1.7)
4.4 Click Next.

4.5 Choose how you want the connect button to appear. It can display just the user's address or the address with tFuel balance.

4.7 Click "Add" Some functions will require additional information such as how much tFuel do you want this button to send to the contract when clicked. (If you added a function you do not want in your Dapp refresh the page to start over.)
4.8 Click "Build and Download" to save your Dapp as an HTML file.

4.9 Copy and paste or upload the file into your web server. (It must be ran from a web server such as Apache or NGINX.)
