 # Python Buildpack Binaries
 
 
+To get started with it, create an app on Heroku inside a clone of this repository, and set your S3 config vars:
+
+    $ heroku create --buildpack https://github.com/heroku/heroku-buildpack-python#not-heroku
+    $ heroku config:set WORKSPACE_DIR=builds
+    $ heroku config:set AWS_ACCESS_KEY_ID=<your_aws_key>
+    $ heroku config:set AWS_SECRET_ACCESS_KEY=<your_aws_secret>
+    $ heroku config:set S3_BUCKET=<your_s3_bucket_name>
+
+
+Then, shell into an instance and run a build by giving the name of the formula inside `builds`:
+
+    $ heroku run bash
+    Running `bash` attached to terminal... up, run.6880
+    ~ $ bob build runtimes/python-2.7.6
+
+    Fetching dependencies... found 2:
+      - libraries/sqlite
+
+    Building formula runtimes/python-2.7.6:
+        === Building Python 2.7.6
+        Fetching Python v2.7.6 source...
+        Compiling...
+
+
+Enjoy :)
