+# This is the first topic
+
+<!--Writerside adds this topic when you create a new documentation project.
+You can use it as a sandbox to play with Writerside features, and remove it from the TOC when you don't need it anymore.
+If you want to re-add it for your experiments, click + to create a new topic, choose Topic from Template, and select the 
+"Starter" template.-->
+
+## Add new topics
+You can create empty topics, or choose a template for different types of content that contains some boilerplate structure to help you get started:
+
+![Create new topic options](new_topic_options.png){ border-effect="line" thumbnail="true" width="321"}
+
+## Write content
+%product% supports two types of markup: Markdown and XML.
+When you create a new help article, you can choose between two topic types, but this doesn't mean you have to stick to a single format.
+You can author content in Markdown and extend it with semantic attributes or inject entire XML elements.
+
+For example, this is how you inject a procedure:
+
+<procedure title="Inject a procedure" id="inject-a-procedure">
+    <step>
+        <p>Start typing <code>procedure</code> and select a procedure type from the completion suggestions:</p>
+        <img src="completion_procedure.png" alt="completion suggestions for procedure" border-effect="line"/>
+    </step>
+    <step>
+        <p>Press <shortcut>Tab</shortcut> or <shortcut>Enter</shortcut> to insert the markup.</p>
+    </step>
+</procedure>
+
+## Add interactive elements
+
+### Tabs
+To add switchable content, use tabs (start typing `tabs` on a new line).
+
+<tabs>
+    <tab title="Markdown">
+        <code-block lang="plain text">![Alt Text](new_topic_options.png){ width=450 }</code-block>
+    </tab>
+    <tab title="Semantic markup">
+        <code-block lang="xml">
+            <![CDATA[<img src="new_topic_options.png" alt="Alt text" width="450px"/>]]></code-block>
+    </tab>
+</tabs>
+
+### Collapsible blocks
+Besides injecting entire XML elements, you can use attributes to configure the behavior of certain elements.
+For example, you can collapse a chapter that contains non-essential information like this:
+
+#### Supplementary info {collapsible="true"}
+Content under such header will be collapsed by default, but you can modify the behavior by adding the following attribute:
+`default-state="expanded"`
+
+## Convert selection to XML
+If you need to extend an element with more functions, you can convert selected content from Markdown to semantic markup.
+For example, if you want to merge cells in a table, it's much easier to convert it to XML than do this in Markdown.
+Position the caret anywhere in the table and press <shortcut>Alt+Enter</shortcut>:
+
+<img src="convert_table_to_xml.png" alt="Convert table to XML" width="706" border-effect="line"/>
