How to update LHC from SSH avoiding updating from SFTP that require long time?

[PeopleInside]

Hi,
I was looking the doc page for the upgrading process https://doc.livehelperchat.com/docs/upgrading

Every time a new version of LHC is available I download the zip file, I unzip and I upload only the suggested folder but this require long time, sometimes more then 30 minutes as SFTP is not fast.

You are using git pull?
Can I ask how it works?

To update with this method I have just to going in the live helper chat folder then run git pull as written or there is a full different command?
Before lunch this command database should be updated in the user interface or the git pull command will update also the database?

Another question:
For keep extensions updated (for example Telegram) I need send other SSH command or git pull will also update extensions?
With command I should use for keep extensions and his database updated?

Thank you very much.

I see some other instructions here: https://livehelperchat.com/how-to-automate-live-helper-chat-updates-338a.html
git pull origin master is the exact command that should be run in the live helper chat root folder?
