Readme created from Go doc with [goreadme](https://github.com/posener/goreadme)

the docs are writting in this file: https://git.xsfx.dev/xsteadfastx/workgroups/src/branch/main/workgroups.go

its about this repo: https://git.xsfx.dev/xsteadfastx/workgroups

maybe someone has an idea. i use goreadme version 1.4.1

ok... it has a problem with the tools.go file. if i delete it... it works... but why? it has a problem with the build tag.
