Added new cfg option. how to set default value at install?

[PhpMadman]

Hi.

 

I'm working on a new feature to add to prestashop @ GitHub.

And I added an text option in BO, similar to Number of days for which the product is considered 'new'.

Now that option comes with an default 20 days. How do I make the same thing for my option.

 

I searched the files, and if i'm guessing right it's the install/-devdata/theme.sql file with the line UPDATE `PREFIX_configuration` SET value = '20' WHERE name = 'PS_NB_DAYS_NEW_PRODUCT'; that sets the default value.

 

Is my guess correct?
