In this case this might not be needed as it is really short paragraph and good to read anyway. Can be a bit on the offensive side too.
You can start with something like: "In case you have experience with development on eth1, you may be familiar with the problem of fast testing and using private networks as a solution." That way you say immediately what's this section about and people can choose to skip or not.

is it a validator client really or more of desktop app for validators or something like that?

From my experience, if I say or write any else then "desktop validator client" people have no idea what I'm talking about. And it is, as a matter of fact, our core functionality

idk, I was referring that technically client is something like lodestar, lighthouse etc.

those are beacon nodes. They do have validators but they are cli tools

| There is couple of ways to start eth2 chain: | ||
|
|
||
| - start from genesis state (we prefer this one as it requires less configuration modification) |

| - start from genesis state (we prefer this one as it requires less configuration modification) | ||
| - we generate genesis state and provide it to beacon node | ||
| - wait for genesis to start |
| - genesis.json - genesis file containing params of our POA chain | ||
| - passwd.txt - some file containing some dummy password for geth to encrypt our account | ||

I think that linking here is not considered good SEO practice. so maybe this would be:

| ### Step 2: Deploy deposit contract | ||
|
|
||
| Eth2 chain will monitor deposit contract for new deposits and use deposit data to activate validator. | ||
| You can download deposit contract artifact for spec version 0.10.1 [here](https://raw.githubusercontent.com/ethereum/eth2.0-specs/v0.10.1/deposit_contract/contracts/validator_registration.json). |

You are linking Prysmatic 2x times and this is kinda hidden linking :D
Rephrase so you only link once the name i.e. At the moment, eth2 has a bunch of short lived single client testnets and one long lived which is Prysmatic's Sapphire Testnet](https://prylabs.net/). However, real stable client testnet is yet to come.
