Is it possible creating a new project from zero using Gnome-Builder?
When I open it, allows me only to load an existing project from my computer or from remote, but I cannot create a new one, but in the official site it is said that it is possible to do it.
Sorry for the bad English.
"New..." is the first button in the titlebar when gnome-builder is started (on the "Select a project" page). It allows you to create a new project using various templates.
Builder is only a couple of years old: If you are using a very old version this feature may not be in it yet (Anything after 3.21 is definitely fine).
