 # Add Mapzen Search geocoder to a map
 
-[Add some intro text about geocoding]
+[Mapzen Search](https://mapzen.com/projects/search) is a modern, geographic search service based entirely on open-source tools and powered entirely by open data. To start integrating Mapzen Search to your apps, you need a [developer API key](api-keys-rate-limits.md). You might use this functionality in any app that has a geographic component, including ones that deliver goods, locate hotels or venues, or even provide local weather forecasts.
 
-To complete the tutorial, you should have some familiarity with HTML and JavaScript, although all the source code is provided. You will need an [API key](https://mapzen.com/developers) to use Mapzen Search, which requires a GitHub account for authorization. You can use any text editor and operating system, but must maintain an Internet connection while you are working. The tutorial should take about an hour to complete.
+Through a process known as [geocoding](search.md), Mapzen Search allows you to use natural language to find a particular place by entering an address or the name of a landmark or business, and then translates the result in to the geographic coordinates for mapping. Mapzen Search is built on [Pelias](https://github.com/pelias), an open-source geocoding project.

+In this walkthrough, you will learn how to make a map with a search box that allows you to enter addresses and place names and locate them on a map.

 To use the geocoding service, you must first obtain an API key from Mapzen. Sign in at https://mapzen.com/developers to create and manage your API keys.
 
-Mapzen Search, powered by Pelias, is a shared geocoding service. As such, there are limitations on requests to prevent individual users from degrading the overall system performance.

 ## Download and install the dependencies
 
-The Leaflet JavaScript library, which provides tools for zooming, displaying attributions, and drawing symbols, is one way you can display the Mapzen Search input box on web and mobile maps. Leaflet is extensible, and developers have built additional tools for Leaflet maps, including the Mapzen Search plug-in.

+Mapzen Search uses a [variety of open data sources](https://mapzen.com/documentation/search/data-sources/), including OpenStreetMap. In some cases, you may be unable to find the location you are expecting, which could be an indicator that the data has limitations. Part of the power of open data is that you are able to correct it.
