+The :ref:`ref-classes-go-vendor` class implements support for offline builds,
+also known as Go vendoring. In such a scenario, the module dependencias are
+downloaded during the :ref:`ref-tasks-fetch` task rather than when modules are
+imported, thus being coherent with Yocto's concept of fetching every source
+beforehand.
+
+The dependencies are unpacked into the modules' ``vendor`` directory, where a
+manifest file is generated.
