+
+[Obsidian](https://obsidian.md/) is a relatively new entrant in the increasingly crowded Markdown knowledge base and note-taking market. Obsidian's excellent Markdown support and its simple, straightforward design makes it a standout application in the category.

+
+Obsidian sports virtually all of the standard fare common to the other applications in this category, but it ups the ante by including a number of other features for power users. There's a visually-striking graph view that's a kind of "mind map" of all your files stored in Obsidian, a "Markdown format importer" that can find and replace certain Markdown syntax elements in your files, and support for [math](https://publish.obsidian.md/help/How+to/Format+your+notes) and [diagram](https://publish.obsidian.md/help/How+to/Format+your+notes) syntax. That really just scratches the surface of Obsidian's capabilities. Obsidian is extensible, and there are dozens of free community plugins available within the application. 
+
+Two other features are worth mentioning. Obsidian provides a simple way to publish notes to the internet, and it stores all of your files in plaintext Markdown files containing only the text you enter.

+
+### Support for Additional Syntax Elements
+
+As an added bonus, Obsidian provides support for several obscure elements.
+
+<table class="table table-bordered" style="font-size: 14px">
+  <thead class="thead-light">
+    <tr>
+      <th>Element</th>
+      <th>Markdown</th>
+      <th>Rendered Output</th>
+    </tr>
+  </thead>
+  <tbody>
+    <tr>
+      <td>Highlight</td>
+      <td><code>==word or phrase==</code></td>
+      <td><mark>word or phrase</mark></td>
+    </tr>
+  </tbody>
+</table>
