+## About
+
 The Mobility Data Specification (**MDS**), a project of the [Open Mobility Foundation](http://www.openmobilityfoundation.org) (OMF), is a set of Application Programming Interfaces (APIs) focused on dockless e-scooters, bicycles, mopeds and carshare. Inspired by projects like [GTFS](https://developers.google.com/transit/gtfs/reference/) and [GBFS](https://github.com/NABSA/gbfs), the goals of MDS are to provide a standardized way for municipalities or other regulatory agencies to ingest, compare and analyze data from mobility service providers, and to give municipalities the ability to express regulation in machine-readable formats.
 
 **MDS** helps cities interact with companies who operate dockless scooters, bicycles, mopeds and carshare in the public right-of-way. MDS is a key piece of digital infrastructure that supports the effective implementation of mobility policies in cities around the world.
 
 **MDS** is an open-source project. It was originally created by the [Los Angeles Department of Transportation](http://ladot.io) (LADOT). In November 2019, stewardship of MDS and the ownership of this repository was transferred to the Open Mobility Foundation. GitHub automatically redirects any links to this repository in the `CityOfLosAngeles` organization to the `openmobilityfoundation` instead. MDS continues to be used by LADOT and many other municipalities.

+## Endpoints
+
 **MDS** is currently comprised of three distinct components:
 
 * The [`provider`][provider] API endpoints are intended to be implemented by mobility providers and consumed by regulatory agencies. When a municipality queries information from a mobility provider, the Provider API has a historical view of operations in a standard format. It was first released in June 2018. Development takes place under the guidance of the OMF's Provider Services Working Group.

 MDS is designed to be a modular kit-of-parts. Regulatory agencies can use the components of the API that are appropriate for their needs. An agency may choose to use only `agency`, `provider`, or `policy`. Or they may select specific elements (endpoints) from each to help them implement their goals.
 
-Many parts of the MDS definitions and APIs align across each other.  In these cases, consolidated information can be found on the [General Information](/general-information.md) page.
