Write your first contract

This tutorial will show you how to deploy a simple contract that has a storage variable you can read and write. You'll be able to update this variable with a transaction and then retrieve the updated value. This is just a simple example to get you started. Solidity is a powerful language that can be used to write complex smart contracts, check out the Next Steps section below after you've finished this tutorial for some more advanced examples!Copy and paste the following code into the file you just created. Remix will detect copy/pasted code and give you a warning about it. This is meant to prevent you from accidentally running malicious code. Always be careful when copy/pasting code from the internet!
