Deploy Solidity smart contract on Acala

Acala supports EVM that allow people to deploy Solidity smart contracts. Please write a tutorial targeting existing Ethereum Solidity smart contract developers on how to deploy a smart contract to Acala using Remix. The tutorial should provide clear instructions for people to follow to Remix to build a smart contract and use Acala Contract UI to deploy and invoke the contract on Acala testnet. We do not have much documents yet so part of the challenge is figuring out the exact steps. Some useful information: Acala repo: https://github.com/AcalaNetwork/Acala Contract UI: https://acala-evm.vercel.app

DevOps challange

Please create a set of steps to manage private keys with different criticalness, including steps to create, store (backup) and use them. Please include steps for low critical keys (insignificant damage if leaked or lost), medium level (significant damage if leaked or lost), and highly critical keys (should NEVER be leaked or lost). Please make the right balances between convenience and security. In the steps, also list the roles will be involved. e.g. DevOps can create and rotate low critical keys and Developer can access it. Multiple Executives will be involoved when creating highly critical keys. Example:
