 # Please see https://go.dev/ref/mod#version-queries for the types of
 # queries that can be used to define a version.
+# If any of these build arguments are not defined then build uses the version
+# already defined in go.mod and go.sum for that module.
+# Note: If the corresponding `_REPO` argument is not defined, `go get` will
+# be used along with `go mod tidy`, which sometimes may change the version you
+# are trying to use because some other module requires the same requirement
+# but of a different version. A trick to overcome this is to also use the
+# `_REPO` argument and just put in the default repository for that module and
+# that will cause a `go mod edit -replace=` to be used instead which won't have
+# this issue.
