 * Hi, in the github readme..md file you have “Custom key Set custom field group
   key. ie: group_custom_name.” But cant seem to find where to add that. Thanks.

 * Hello,
 * In order to customize your field group key you have to open the screen options
   in the top right corner of the field group, and check the “Slug” field.
 * You’ll then find the slug field at the bottom of the field group, just like any
   other post type.

 * Please note: your field group slug must start with `group_`.
 * Have a nice day!
 * Regards.

 * Hi, thanks for the info, this issue there is if the field group is already existing(
   and php is outputted) the field group is duplicated – [https://www.screencast.com/t/leg9WShDVb](https://www.screencast.com/t/leg9WShDVb)
   So you have to manually delete the extra field groups from your theme folder.

 * Hello,
 * Yep, this will generate a new field group & sync file when used. There’s not 
   much to do about that for now, that’s how ACF is working.
 * Have a nice day!
 * Regards.
