Houston, we've had a problem https://www.youtube.com/watch?v=MdvoA-sjs0A

That option contains a BASE64 encoded serialized mess. In shell:

echo $ACF_OPTION | php -r 'echo unserialize(base64_decode(fgets(STDIN)))["key"]; echo PHP_EOL;'

ps. the key itself is also a BASE64 encoded pipe-separated string

@szepeviktor yeah, saw you're sternly worded tweet. seemed to get their attention!

Hi @szepeviktor! I'd like to send people in the right direction when they are looking for an ACF license key. Because this project is not ACF exclusive I'd like to keep it short, though. Maybe we add a repo wiki page with usage examples where we can elaborate (e.g. including the shell snippet you mentioned) and link to it in the README?

[szepeviktor]

Okay.

[szepeviktor]

Ooops, there is no Wiki.
