@saghul can you please review again? I want to get this into master 😋

This also needs rebase.

Hi,

Can you explain what done this command tpl, when you replace cp /defaults/nginx.conf /config/nginx/nginx.conf by tpl /defaults/nginx.conf > /config/nginx/nginx.conf ?

Thanks. Philippe

@PhilippeAccorsi That's a little helper templating tool we use.

I have finally rebased my changes on latest master and added the README changes to the handbook: jitsi/handbook#105

[flecno]

Rebased again

[flecno]

Hey @saghul, do you see any chance to get this merged if I rebase this again?

[JannikEmmerich]

@saghul What's the status on this?

[saghul]

Sorry, this fell through the cracks :-/ It needs a rebase though.
