-#### Composer
-Install the [composer package] by running the following command:
+```sh
+composer require erusev/parsedown
+```
 
-    composer require erusev/parsedown

 [latest release]: https://github.com/erusev/parsedown/releases/latest "The latest release of Parsedown"
 
-### Example
+## Example
 
-``` php
+```php
 $Parsedown = new Parsedown();
 
 echo $Parsedown->text('Hello _Parsedown_!'); # prints: <p>Hello <em>Parsedown</em>!</p>
-// you can also parse inline markdown only
+```
+
+You can also parse inline markdown only:

 echo $Parsedown->line('Hello _Parsedown_!'); # prints: Hello <em>Parsedown</em>!
 ```
 
 More examples in [the wiki](https://github.com/erusev/parsedown/wiki/) and in [this video tutorial](http://youtu.be/wYZBY8DEikI).
 
-### Security
+## Security
 
 Parsedown is capable of escaping user-input within the HTML that it generates. Additionally Parsedown will apply sanitisation to additional scripting vectors (such as scripting link destinations) that are introduced by the markdown syntax itself.
 
 To tell Parsedown that it is processing untrusted user-input, use the following:
+
 ```php
-$parsedown = new Parsedown;
-$parsedown->setSafeMode(true);
+$Parsedown->setSafeMode(true);
 ```
 
 If instead, you wish to allow HTML within untrusted user-input, but still want output to be free from XSS it is recommended that you make use of a HTML sanitiser that allows HTML tags to be whitelisted, like [HTML Purifier](http://htmlpurifier.org/).
 
 In both cases you should strongly consider employing defence-in-depth measures, like [deploying a Content-Security-Policy](https://scotthelme.co.uk/content-security-policy-an-introduction/) (a browser security feature) so that your page is likely to be safe even if an attacker finds a vulnerability in one of the first lines of defence above.
 
-#### Security of Parsedown Extensions
-
 Safe mode does not necessarily yield safe results when using extensions to Parsedown. Extensions should be evaluated on their own to determine their specific safety against XSS.
 
-### Escaping HTML
-> ⚠️  **WARNING:** This method isn't safe from XSS!
+## Escaping HTML

-If you wish to escape HTML **in trusted input**, you can use the following:
 ```php

 ```
 
-Beware that this still allows users to insert unsafe scripting vectors, such as links like `[xss](javascript:alert%281%29)`.
