In this post, I will show the simple way and easy way to develop contract, so that everyone can easily deploy the contract by yourself, even you don't know how to coding.
Before you start below step, please prepare the Rinkeby testnet setting on your MetaMask and get the ETH in your testnet wallet.
Setup Rinkeby testnet in your metamask (check [image1] below)
How to get your ETH free in your testnet (connect the wallet and send the request, you will get 0.1ETH, repeat about 5 times, that's enough): https://faucets.chain.link/rinkeby

Using online ETH IDE Remix : https://remix.ethereum.org/
Follow the step of below image to upload the contract
In below image, for the red portion I circle, if you develop on to the ETH network, you can't modify them, they are important, please make sure you have a correct setting before you start developing, you can modify after development on green portion, green portion meaning as below : #mintPrice : What price you want to sell your NFT #maxAmountPerMint : the limitation of each one transaction #maxMintPerWallet : the limitation of each wallet can mint.
After you change all the setting, go the solidity compiler to finish compile, follow the below image to compile, if success, you will see the green tick.
Deploy your contract on Rinkeby testnet, follow the below image to finish deploying contract.
After the transaction is finished, that means your contract already on the rinkeby testnet, you can see the image as below.
Now you can interact with your contract on remix, check the below image, some website you may need to set them.
