# OS MRN Getting Started Guide

This getting started guide provides instructions for using OS MRN in different routing software applications. Users with limited technical knowledge will be able to follow this guide.

OS Multi-modal Routing Network (OS MRN) is designed for use in routing applications. Numerous different routing software applications are available.

This guide includes instructions to get you started with using OS MRN in three open-source routing applications:

* [pgRouting](/os-downloads/products/transport-network-portfolio/os-multi-modal-routing-network/os-mrn-getting-started-guide/pgrouting.md) – for GeoPackage (GPKG) and Protocolbuffer Binary Format (PBF)
* [GraphHopper](/os-downloads/products/transport-network-portfolio/os-multi-modal-routing-network/os-mrn-getting-started-guide/graphhopper.md) – for PBF
* [OpenTripPlanner ](/os-downloads/products/transport-network-portfolio/os-multi-modal-routing-network/os-mrn-getting-started-guide/opentripplanner.md)– for PBF

There are additional pages included in this guide that cover:

* [Working with OpenStreetMap (OSM) files](/os-downloads/products/transport-network-portfolio/os-multi-modal-routing-network/os-mrn-getting-started-guide/working-with-openstreetmap-files.md), where you will find guidance on:
  * [What tools you can use to convert from PBF to OSM XML](/os-downloads/products/transport-network-portfolio/os-multi-modal-routing-network/os-mrn-getting-started-guide/working-with-openstreetmap-files.md)
  * [Sorting OSM files](/os-downloads/products/transport-network-portfolio/os-multi-modal-routing-network/os-mrn-getting-started-guide/working-with-openstreetmap-files.md)
* [Using OS MRN with ESRI Network Analyst](/os-downloads/products/transport-network-portfolio/os-multi-modal-routing-network/os-mrn-getting-started-guide/using-os-mrn-with-esri-network-analyst.md)

{% hint style="info" %}
The ability to carry out multi-modal routing is dependent on the software you use. To make full use of the functionality of OS MRN, you may need to make configuration changes to your software, for example, configuring it to use the speed data or time conditional attributes. It is also possible to use third-party datasets, such as bus and train timetables, with OS MRN to enhance multi-modal routing.

## How to get this product

OS MRN data can be downloaded from the [OS Data Hub](https://osdatahub.os.uk/) (for further guidance, please see [Creating data packages and downloading data](https://osdatahub.os.uk/support/faqs/downloads)). You can select a data format (PBF or GeoPackage) during the download process. OS MRN is available as a Full Supply only, and you can order full Great Britain (GB) coverage or a customisable area of interest (AOI).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.os.uk/os-downloads/products/transport-network-portfolio/os-multi-modal-routing-network/os-mrn-getting-started-guide.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
