## Download and install the dependencies
The Leaflet JavaScript library provides tools for building an interactive map for web and mobile devices. Leaflet is extensible, and developers have built additional tools for Leaflet maps, including the Mapzen Search geocoder plug-in.
To set up your development environment for this walkthrough, you need to download the geocoder plug-in. You do not need to download the Leaflet files because you will be referencing them from a web server.
1. Download the zip file from https://github.com/pelias/pelias-doc/raw/master/geocoding-tutorial.zip.
2. Find the file in your default downloads directory and unzip it. It should unzip to a folder named `geocoding-tutorial`. (Note that some browsers, such as Safari, may unzip automatically.)
3. Make sure your `geocoding-tutorial` folder has `pelias-leaflet-geocoder.css`, `pelias-leaflet-geocoder.js`, an images folder, and two HTML files.
## Create an index page
With the files downloaded, you are ready to start building your map. You will need to use a text editor to update the HTML.
You are ready to start building your map. You will need to use a text editor to update the HTML.
Suggested text editor applications include [Atom - OS X, Windows, Linux](https://atom.io/); [Notepad++ - Windows](https://notepad-plus-plus.org/); [TextWrangler - OS X](http://www.barebones.com/products/textwrangler/); and [Sublime - OS X, Windows, Linux; free trial](http://www.sublimetext.com/). While you can use the apps installed with your operating system, such as Notepad or TextEdit, they do not provide the helpful indentations, code coloring and autocomplete, or text alignment options found in the other editors. For TextEdit, you must go to the Format menu and click Make Plain Text to use the plain-text version of the file. Do not use an app that applies rich formatting, such as Word or Wordpad.
The geocoding-tutorial folder contains two HTML files: `index.html` is the file you will start with and update in the steps, while `index-complete.html` is a finished version to check your work or review if you need to troubleshoot an error.
1. From your `geocoding-tutorial` folder, open `index.html` in a text editor. It should look like this:

## Add references to CSS and JavaScript files
The Leaflet JavaScript library provides tools for building an interactive map for web and mobile devices. Leaflet is extensible, and developers have built additional tools for Leaflet maps, including the Mapzen Search geocoder plug-in.
A cascading style sheet (CSS) is used to style a webpage, including layout and fonts, and JavaScript adds functionality to the page. In your `index.html` file, you need to list the CSS and JavaScript files required for building a page with Leaflet and the geocoder plug-in.

## Add a map to the page
To display a Leaflet map on a page, you need a `<div>` element, which is a container on the page that groups elements, with an ID value. If you want to know more about initializing a Leaflet map, see the [Leaflet getting started documentation](http://leafletjs.com/examples/quick-start.html).
