+# This file provides common Makefile infrastructure for several Prometheus
+# components. This includes make tasks for downloading Go, setting up a
+# self-contained build environment, fetching Go dependencies, building
+# binaries, running tests, and doing release management. This file is intended
+# to be included from a project's Makefile, which needs to define the following
+# variables, at a minimum:
+#
+# * VERSION - The current version of the project in question.
+# * TARGET  - The desired name of the built binary.
+#
+# Many of the variables defined below are defined conditionally (using '?'),
+# which allows the project's main Makefile to override any of these settings, if
+# needed. See also:
+#
+# https://www.gnu.org/software/make/manual/html_node/Flavors.html#Flavors.
+#
+# The including Makefile may define any number of extra targets that are
+# specific to that project.
