# Tutorial: Add SYMM

Add SYMM to an existing Builders NFT

Open the [Builders NFT app](https://app.symmio.foundation/builders-nft?utm_source=chatgpt.com) and connect the wallet that holds your NFT.

Select **“I already have an NFT”** and follow the app’s prompts to identify your existing NFT and enter the additional SYMM amount you want to commit.

> Capture the “I already have an NFT” view with the existing NFT identified and an additional SYMM amount entered. Show the existing commitment and any applicable minimum where the app displays them. Highlight the additional-amount field and main action button.

Review and complete any approval and transaction confirmations requested by the app. Once the transaction has confirmed, check that your NFT’s committed SYMM amount has increased by the amount you added.
