15−Binary executables are placed in `/app/.local/bin/` after compilation, a directory which Heroku includes in your `$PATH`, so assuming that your application is [binding to `$PORT`](https://devcenter.heroku.com/articles/dynos#web-dynos), you can serve your app by [creating a `Procfile`](https://devcenter.heroku.com/articles/procfile) at your project root that defines a `web` process type for the `executable` defined in your `.cabal` file:

23−### Templating stack.yaml
24−
25−To avoid committing secrets into `stack.yaml` for access to private
26−repos, an app's config vars values can be substituted for tags
27−enclosed in double brackets. For example, given a `stack.yaml` containing:
28−
29− packages:
30− -location:
31− git: https://mfine:{{GITPASS}}@github.com/mfine/heroku-buildpack-stack.git
32−
33−and an application with config vars:
34−
35− $ heroku config -app calm-storm-51595
36− === murmuring-beyond-51595 Config Vars
37− GITPASS: abc123
38− $
39−
40−before compilation, the `stack.yaml` will be substituted as follows:
41−
42− packages:
43− -location:
44− git: https://mfine:abc123@github.com/mfine/heroku-buildpack-stack.git
45−

47−### Makefile Support
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:
55− stack build --copy-bins
