It starts them off coding and ends with a complete basic “Hello World” project. Introductory tutorials demonstrate how to build a key feature of AMP in a step-by-step process.

It should identify the feature, describe what it is, and finish with what it does. Introductory guides introduce a developer to the basic requirements of the feature without directing them to implement it. If you’re walking through a process step by step with code samples, you’re probably writing a tutorial. If you're outlining all the programmatic elements for an AMP component, you're probably writing a reference document.</p> <p>amp.dev examples: - <a href="/documentation/guides-and-tutorials/learn/email_fundamentals/?format=email">AMP email fundamentals</a> - <a href="/documentation/guides-and-tutorials/learn/common_attributes/?format=websites">Common element attributes</a></p> <table> <tbody><tr> <td> <strong>Do</strong> </td> <td><strong>Don’t</strong> </td> </tr> <tr> <td>Identify what the document will cover. </td> <td>Break down into a step-by-step process. </td> </tr> <tr> <td>Introduce features and concepts.

A concept guide is like a topographic map. It shows the various trails in the area with details such as elevation changes, but it doesn’t prescribe a specific route through the terrain. Explain what a feature is and how it functions rather than how to build a feature.</p> <p>amp.dev examples:</p> <ul> <li><a href="/documentation/guides-and-tutorials/develop/animations/triggering_css_animations/?format=websites">Animate &amp; transition</a></li> <li><a href="/documentation/guides-and-tutorials/optimize-and-measure/configure-analytics/?format=websites">Track engagement with analytics</a></li> <li><a href="/documentation/guides-and-tutorials/develop/style_and_layout/?format=websites">Style &amp; layout</a></li> </ul> <table> <tbody><tr> <td> <strong>Do</strong> </td> <td><strong>Don’t</strong> </td> </tr> <tr> <td>Provide the developer with all the elements needed to construct a solution. </td> <td>Actively guide the developer to specific end state. </td> </tr> <tr> <td>Cover all aspects of the subject areas. </td> <td>Focus on a specific task. </td> </tr> <tr> <td>Include visual aids, such as diagrams or screenshots. </td> <td>Overthink this, you can request help for visual aids from the [outreach working group](https://github.com/ampproject/wg-outreach). </td> </tr> <tr> <td>Provide code samples and link out to other guides. </td> <td>Provide a download to a finished project or stray off topic. </td> </tr> </tbody></table> <h2 id="reference-documentation">Reference documentation <a name="reference-documentation"></a></h2> <p>Reference documentation lists all the programmatic elements for an AMP component.
