48+
49+This buildpack now supports an optional Makefile, in case you need to coordinate
50+other build steps with Stack. It assumes that the Makefile includes a `make
51+install` target that uses the Stack build command with the flag `--copy-bins`.
52+For example, a possible `install` target configuration in the Makefile could be:
53+
54+ install:
