 ### Print Angular comments
 
+Angular adds some comments to our HTML file. Usually, when debugging our tests, we don't need them. Therefore they
+are not printed by default. However, there are cases where you want to print those comments. To do so, you
+can pass `true` as an additional flag tot he `logNgHTML` method.
+
 ```
 console.logNgHTML(fixture, true);
 ```
 
 ### Change the theme
 
+`@angular-extensions/pretty-html-log` allows you to print the html logs in different themes.
+Currently, we support (DRACULA, VSCODE and MATERIAL). The themes can be importet from `pretty-html-log`, the
+base library `@angular-extensions/pretty-html-log` depends on.
