I think it is important to list the executable demo first before mentioning the compilable demo code. "here, you can try this. It runs out of the box. And if you want to compile it yourself: here is the code, but you need this and that".

The wiki ends with a link to the demo code. A link to the executable could be included right before the code link, i think:

The Configuring your Windows section has a duplicate section within the same page.

The duplicate sections each use a different BackgroundBrush in their examples but are otherwise identical. One of these should be removed.

Oh, I was just going to create a new issue about this duplication. I am glad I found this issue.

FWIW, the duplication was added in this commit and a diff of those two sections (using line numbers relative to that first line in each section) is

7c7
<         Background="{DynamicResource MaterialDesignBackground}"
---
>         Background="{DynamicResource MaterialDesignPaper}"
16c16
<         Background="{DynamicResource MaterialDesignBackground}"
---
>         Background="{DynamicResource MaterialDesignPaper}"

where the the left/first file in the diff is the first occurance of the "Configuring your Window(s)" section (so the right/second file in the diff is the second occurance of the section).

Is this still something that needs done?

@Christian-Oleson yes, i have been busy with other items and haven't had a change to go back to it (though some of the other docs have been updated). It is specifically about the main README page and the items under the Getting Started heading.
