+├── designer-plugin-collection  # Adding a collection of widget plugins to Qt Designer
+└── README.md
+```
+
+This directory contains a `CMakeLists.txt`, which can be selected to open as a 
+project within your preferred IDE. From there, all nested examples can be built,
+debugged, and ran.
+
+The plugin examples will need to be installed for Qt Designer integration to work.
+On Linux, Qt Designer looks under `/some/path/to/Qt/Tools/QtCreator/lib/Qt/plugins/designer/`.
+On windows or Mac, this path may differ. Unfortunately I don't have these machines to test for myself.
+
+```bash
+cd klips/cpp/qt/designer-plugin-collection
+mkdir build && cd build
+cmake .. && cmake --build . --target install
+```
+
+After installing the plugin collection example above, we can open Qt Creator and navigate to the Designer.
+We should see the custom collection is available within the Designer, and the contents of the widgets render correctly in the application view.

+
+Sitemap generator I created while learning some C#.
+Example of using the library is in `ConsoleApp/Program.cs`, files used for testing are in `ConsoleApp/TestFiles/`
+`ConsoleApp/TestFiles/sitemap.xml` currently contains the sitemap for my website.
+If we run the console application with a different URL that targets this same file, the file will be overwritten with the new sitemap.
+There is no need to delete or recreate files manually.
+
+I plan to check for a `robots.txt` while generating sitemaps to prevent crawling pages that aren't useful.
+For now there is no use for a `robots.txt`, the `SiteMap.Crawl()` function visits the URL provided to the `SiteMap` constructor.
+Regex is used to check the visited page and match URLs with the same base domain, the URLS found are logged for the crawler to visit.
+Each time we finish collecting URLS on a page, we move to the next URL in the queue and repeat this process.
+Once we finish crawling all URLs, an XML sitemap is generated where the URLs are sorted by their length.
+
+I used [sitemaps.org - XML Format](https://www.sitemaps.org/protocol.html) to determine the proper formatting for the sitemap.
+For now, since the web application I used for testing does not respond with [Last-Modified](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Last-Modified) in the HTTP header, the last modified time is set to the date the sitemap was generated.
+The `priority` fields are all set to the default value indicated on sitemaps.org, which is `0.5`. 
+This is to avoid confusing crawlers with a huge list of 'top-priority' pages to crawl.
+All `changefreq` fields of the sitemap are marked as `daily`.
+
+The primary motivation for this project was learning about unmanaged resources in C#, and trying out the [Dispose Pattern](https://docs.microsoft.com/en-us/dotnet/standard/garbage-collection/implementing-dispose?redirectedfrom=MSDN#implement-the-dispose-pattern) for myself.
+If someone reading this were to find a problem with the way I handled disposing of the `HttpClient` in the `SiteMap` class, feel free to let me know :) Creating an issue, PR, or sending an email is all acceptable.
+
+### Future plans
+* Parse `robots.txt` to avoid crawling pages that are not desired
+* Test the generator with an application that serves `LastModified` date; Use it if available
+* Set `priority` in a more useful way, or allow some form of customization of the way this is handled.
+* Set `changefreq` in a more useful way, or allow some form of customization of the way this is handled.
+* Generate a regex pattern to match, if one is not provided
+
+For now, the general use of this library is seen in the example below.
+
+```C#
+using SiteMapLibrary;
+
+// Create an XmlManager to use for generating our sitemap; Provide a file path (and optional Xml settings; See ctor)
+var mgr = new XmlManager("/home/kapper/Code/klips/dotnet/sitemap/ConsoleApp/TestFiles/sitemap.xml");
+// If we want to output the sitemap to the console, instead of saving to a file
+// var mgr = new XmlManager("Console.Out");
+
+// Provide a base URL to start crawling, an XmlManager, and a Regex pattern to use for matching URLs while crawling
+using SiteMap siteMap = new SiteMap("https://knoats.com", mgr,
+  new("(http?s://knoats.com(?!.*/dist/|.*/settings/|.*/register/|.*/login/|.*/uploads/|.*/export/|.*/search?).*?(?=\"))"));
+// Start crawling; When this returns, we have visited all found URLs and wrote them to our sitemap
+await siteMap.Crawl();
+```
