-Note that in both cases we `go get` the `/v2/ginkgo` subpackage.  This pulls in the CLI and its dependencies.  If you only `go get github.com/onsi/ginkgo/v2` you may experience issues installing the cli - if you do simply run `go get github.com/onsi/ginkgo/v2/ginkgo` to fetch the missing dependencies.

 ### Support Policy
 
 Ginkgo adheres to semantic versioning - the intent is for there to be no breaking changes along the `2.m.p` line with new functionality landing as minor releases and bug-fixes landing as patch releases (fixes are never back-ported).  We work hard to maintain this policy however exceptions (while rare and typically minor) are possible, especially for brand new/emerging features.

-This alone, however, is often not enough.  The Ginkgo CLI includes additional dependencies that aren't part of the Ginkgo library - since your code doesn't import the cli these dependencies probably aren't in your `go.sum` file.  To get around this it is idiomatic Go to introduce a `tools.go` file.  This can go anywhere in your module - for example, Gomega places its `tools.go` at the top-level.  Your `tools.go` file should look like:
-
-```go
-//go:build tools
-// +build tools
-
-package main
-
-import (
-  _ "github.com/onsi/ginkgo/v2/ginkgo"
-)
-```
-
-The `//go:build tools` constraint ensures this code is never actually built, however the `_ "github.com/onsi/ginkgo/v2/ginkgo` import statement is enough to convince `go mod` to include the Ginkgo CLI dependencies in your `go.sum` file.

 Once you have `ginkgo` running on CI, you'll want to pick and choose the optimal set of flags for your test runs.  We recommend the following set of flags when running in a continuous integration environment:
 
 ```bash
