+## User-flow
+
+When a user enrolls in a self-paced course and the necessary flags and
+configurations are enabled, a Schedule and ScheduleExperience is created for
+them. The Schedule has an upgrade deadline set for some number of days from the
+enrollment date.
+
+## Getting Started
+
+These instructions assume you have already setup an Open edX instance or have a
+Running devstack. See the [Open edX Developer's
+Guide](http://edx.readthedocs.io/projects/edx-developer-guide/en/latest/) for
+information on how to set those up.
+
+### Setting up edX Automated Communication Engine (A.C.E.)
+
+The Schedule app relies on ACE, which requires a
+[Sailthru](http://www.sailthru.com/) back-end for sending emails. See the
+[edx-ace
+documentation](https://edx-ace.readthedocs.io/en/latest/getting_started.html#sailthruemailchannel-settings)
+for instructions on setting up a Sailthru channel in ACE.
+
+### Django Settings
+
+Edit the `lms.env.json` and add/change the following:
+
+```python
+FEATURES = {
+    'ENABLE_MKTG_SITE': True,
+}
+MKTG_URLS = {
+    'ROOT': '<insert_lms_url_here>',
+}
+SOCIAL_MEDIA_FOOTER_URLS = {
+    'tumblr': '<insert_tumblr_url_here>',
+    'reddit': '<insert_reddit_url_here>',
+    'twitter': '<insert_twitter_url_here>',
+    'google_plus': '<insert_google_plus_url_here>',
+    'youtube': '<insert_youtube_url_here>',
+    'linkedin': '<insert_linkedin_url_here>',
+    'meetup': '<insert_meetup_url_here>',
+    'facebook': '<insert_facebook_url_here>',
+}
+MOBILE_STORE_URLS = {
+    'google': '<insert_play_store_url_here>',
+    'apple': '<insert_app_store_url_here>',
+}
+CONTACT_MAILING_ADDRESS = '<insert_physical_address_here>'
+ACE_ENABLED_CHANNEL = ['sailthru_email']
+ACE_ENABLED_POLICIES = ['bulk_email_optout']
+ACE_CHANNEL_SAILTHRU_TEMPLATE_NAME = '<insert_sailthru_template_name_here>'
+```
+
+### Configuration Models
+
+Make sure a Site has been created at `<lms_url>/admin/sites/site`.
+
+In the Django admin panel at `<lms_url>/admin/schedules/scheduleconfig/` create
+a ScheduleConfig and link it to the Site. Make sure to enable all of the
+settings:
+
+* `create_schedules`: enables creating new Schedules when new Course Enrollments
+  are created.
+* `enqueue_*`: allows sending email tasks of this message type to celery.
+* `deliver_*`: allows delivering emails through ACE for this message type.
+* `hold_back_ratio`: ratio of all new Course Enrollments that should NOT have a
+  Schedule created.
+
+If you are testing with a particular course, make sure that it is self-paced by
+going to `<studio_url>/admin/self_paced/selfpacedconfiguration/` and add an
+enabled self paced config. Then, go to Studio settings for the course and change
+the Course Pacing value to "Self-Paced". Note that the Course Start Date has to
+be set to sometime in the future in order to change the Course Pacing.
+
+### Waffle Flags and Switches

+
+All waffle flags and switches can be created at `<lms_url/admin/waffle/`.
