I think this this be included in the in june sprint.

Add a section to home page "why essential eth" with this information

• the issues with ethers and web3.js
• how much how much smaller the overall bundle size of the application becomes with ee vs. ethers
• how this makes dapps faster
• the importance of multiple libraries (we're in big trouble if everyone is using ethers and a bug gets added to library)
• A focus on Devex

We've gotta have a monopoly on "get started easy" type of a code samples ✅

Also a quick way to find what you need like "how do i convert ether to wei" would help make this a great place to get started as a beginner looking to do EVM things with js/ts
