 The NFT Resolver is intented to be used to resolve any subdomain for a specific ENS domain where a NFT collection has been deployed on Linea.  
 More precisely it is ID based, meaning the resolution of an address for a subdomain is determined by the ownership of the NFT's ID on the target NFT contract on Linea.
 
+## Setup for your own ENS domain for your own NFT collection
+
+TODO: The NFT Resolver contract address needs to be changed to the one deployed on mainnet once deployed.
+
+If you own an ENS domain that you want its subdomains to resolve depending on a NFT collection deployed on Linea, simply follow those steps:
+
+1 - Get the DNS encoded name of your ENS name, you can use etherJs dnsEncode function to get it: https://docs.ethers.org/v6/api/hashing/#dnsEncode  
+For example for `efrogs.eth`, the DNS encoded name is `0x066566726f67730365746800`  
+2 - Get the target NFT contract you want to use to resolve the subdomains depending on the NFT's owner addresses.  
+For example: [0x194395587d7b169e63eaf251e86b1892fa8f1960](https://lineascan.build/address/0x194395587d7b169e63eaf251e86b1892fa8f1960)  
+3 - Go to the [NFT resolver contract](https://sepolia.etherscan.io/address/0x52992f84Af8204A84cB7F1f7106a59B14882A6E2#writeContract)  
+4 - Click on `Connect to Web3`with the wallet that owns the chosen ENS name (Example `efrogs.eth`)  
+5 - Click on `setTarget` and add the parameters:  
+ name: [DNS encoded name of your ENS name] (Example `0x066566726f67730365746800`)  
+target: [NFT contrac address on Linea] (Example `0x194395587d7b169e63eaf251e86b1892fa8f1960`)  
+6 - Click on write and approve the transaction  
+7 - Go the [ENS app website](https://app.ens.domains/)  
+8 - Go to your ENS name profile page (Example: https://app.ens.domains/efrogs.eth)  
+9 - Go to the tab `More` (Example: https://app.ens.domains/efrogs.eth?tab=more)  
+10 - In the `Resolver` section at the bottom, click on `Edit`  
+11 - Click on `Custom Resolver`  
+12 - Add the NFT Resolver's address: `0x52992f84Af8204A84cB7F1f7106a59B14882A6E2`  
+13 - Click on `Update`, `Open Wallet`and approve the transaction.
+
+Once all those steps are done you can start resolving subdomains of your ENS domain using the NFT IDs minted on Linea.
