Can you please add to README how to use this feature?

[ilyakaznacheev]

@dikkini already there: https://github.com/ilyakaznacheev/cleanenv#model-format

[dikkini]

I got an error:

[ilyakaznacheev]

Can't see your screenshot for some reason...

Feel free to create an issue about that with a description and a screenshot and we'll continue there.

It should be `env-required:"true"`

Example

[ilyakaznacheev]

So that Golang tag syntax requires you to provide tags in a key-value format. Here env-required is a key, and true is a value.

[dikkini]

it works. thanks. but in readme not this syntax.

[ilyakaznacheev]

Maybe I will include it to Godoc examples, thanks for the idea
