+Heroku Buildpack: Shell
+=====================
+
+Run custom commands during the build process.
+
+
+Description
+-----------
+
+This buildpack allows to execute arbitrary commands on the build dyno during the build process.
+
+Just create the file `.heroku/run.sh` in the root directory of your application and write in this file the commands that you want to execute. This file is then ran in *subshell* by the `compile` script of this buildpack. That is, the commands in `.heroku/run.sh` are executed on the build dyno as they would be part of the `compile` script.
+
+Available build-specific variables are `BUILD_DIR`, `CACHE_DIR`, and `ENV_DIR`.
+
+The initial working directory is the root directory of your application(BUILD_DIR).
+
+Usage
+-----
+
+Simply do:
+
+~~~bash
+# Create file '.heroku/run.sh' containing bash commands
+echo 'echo "hello world"' >.heroku/run.sh
+
+heroku buildpacks:set https://github.com/niteoweb/heroku-buildpack-shell.git
