Getting started with ENS

Task Url: https://gitcoin.co/issue/ensdomains/docs/10/2816

What is ENS

ENS (Ethereum Name Service) is analogous to DNS (Domain Name System) for IP addresses, in that it maps a memorable shortcut to an address. ENS is a distributed, decentralized, open, and extensible naming system based on the Ethereum blockchain and a useful tool for developers to create more memorable names for their dapps.

An ENS name can be a subdomain of the root .eth domain, like "example.eth" or any subdomain of a subdomain, like "sub.example.eth", or "wallet.username.example.eth"

Using ENS we can map a friendly ENS name, e.g., "ethereum.eth", to an unfriendly Ethereum address, e.g., 0xfB6916095ca1df60bB79Ce92cE3Ea74c37c5d359. Users can then use the friendly name instead of the address, making it easier to remember, and reducing the chance of errors.

SSH keypair setup for GitHub (or GitHub/GitLab/BitBucket, etc, etc)

Create a repo.

Make sure there is at least one file in it (even just the README.md)

Generate a SSH key pair (private/public):

ssh-keygen -t rsa -C "[email protected]"

Base64 translates 24 bits into 4 ASCII characters at a time. First,
3 8-bit bytes are treated as 4 6-bit groups. Those 4 groups are
translated into ASCII characters. That is, each 6-bit number is treated
as an index into the ASCII character array.

If the final set of bits is less 8 or 16 instead of 24, traditional base64
