# Creating my first NFT collection Assuming that you have already read the previous topics, let's get down to business. You will learn how to create your contracts with digital collectibles easily and for free (using the Polygon testnet, Mumbai). {% hint style="info" %} Get some free tokens at for Polygon Mumbai testnet. You will need them to test your minting process before doing it on the [available-networks](https://docs.dexkit.com/defi-products/dexappbuilder/available-networks "mention"). {% endhint %} Let's do it! 1. **The first thing is to visit the Contract Wizard site** \[]. Once there you should connect your web3 wallet following the image below

Connecting your wallet at first is mandatory.

2. Once connected you will be able to see the dashboard with the collections you have. As you are a new user, you will see this blank screen, only with the options to start creating your collections.

Your ERC-20 address should appear at the top right and the blue «Create» button will be available now to start. Hit there.

3. **In this section we will enter the initial data of our collection.** Be specific and fill all the blanks. Keep in mind that after being minted in the blockchain **you will not be able to change any collection metadata**, so take your previsions. {% hint style="info" %} For KIT holders: if user holds 1,000 KIT it will have right to generate 50 images per month. The balance will be automatically fetched in the wallet while creating the collection. {% endhint %}

KIT holders can generate their collection cover with AI.

4. Please wait until the modal finish it's job minting your collection metadata until the second green ✅

Your collection is ready to receive the NFTs! Click on «View collection» blue button to proceed.

5. The time has come to mint NFTs for our collection! 🥳 **We truly hope you read all the** [requirements](https://docs.dexkit.com/defi-products/dexcontracts/requirements "mention"). If you didn't yet, please give them a look. You're still on time! 🏃‍♀️

Click on «Add NFT» to start creating your first one.

6. Here we will proceed to fill in the data of our first NFT. Let's unravel this process for the sake of your better understanding: * **NFT image:** load your picture. Any image format is allowed, so in the case you don't see any of your images just type in the OS search `*.*`\ All files will appear in your screen and you can now choose your pictures. * **Quantity:** Maximum 20 pieces per NFT. 30 per first push and unlimited minting after creating. We pushed a top number to avoid contract bottlenecking. * **Name:** the name of this specific digital collectible. * **Description:** What is this NFT about? You can add your description using Markdown language and embed external links as well. {% hint style="success" %} 💡 If you plan to use our AI imaging tool, please note that each attempt will still count towards your quota. **Be precise in the description.** {% endhint %}

Check out how this tool works in action.

* Traits: this part is totally up to you and to your collection needs. If you are minting a very unique collection with rare items you can use the trait indicators to make each piece special. 7. This last action \[Create NFTS] will open another modal. Accept every interaction in your wallet as we explain in the Nº4. 8. If the modal went fine, you should see your new collection clicking on \[]
