`go.bbclass` is not documented in the reference manual. Likewise, GO_IMPORT, which seems to be required, is not mentioned in the variable glossary. Looking at the example recipe for Go ( https://git.yoctoproject.org/cgit.cgi/poky/tree/meta/recipes-extended/go-examples/go-helloworld_0.1.bb ), GO_INSTALL and GO_WORKDIR might also need documenting.
Submitted a first version of such docs. Reviews are most welcome! https://lists.yoctoproject.org/g/docs/message/3603
