# Introduction

Here you will find tutorials that cover the main features of the viewer. Step by step, you will build a complete viewer example by adding a feature at a time.

# How to start

The code examples on the following tutorials can be used in different way.

The simplest way is to start with the following code (index.html):

<!DOCTYPE html>
<html lang="en" dir="ltr">
  <head>
    <meta charset="utf-8" />
    <title>BIMDataViewer - Tutorials</title>
    <script src="https://www.unpkg.com/@bimdata/viewer@1.7.4"></script>
  </head>

  <body>
    <div style="height: 100vh">
      <div id="viewerId"></div>
    </div>

    <script>

      /******* INSERT COMPLETE CODE EXAMPLES HERE *******/

    </script>
  </body>
</html>

You just need to have the viewer installed (via CDN) and add a div with an id attribute (e.g. "viewerId"). Then paste the Complete code example sections you will find on the tutorials in the <script> tag above, and open that index.html in a compatible browser.

# Tutorials list

TIP

It is a good idea to do this tutorials in order as code is added to the same file step by step.

# What do I do next?
