+
+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");

+This is a testing project I created while first learning C#.
+There's no objective or goal, aside from playing with different features of C# and NuGet packages.
+Essentially, this is a scrap project that I code in while learning new C# things.
+Since this is just for learning, I won't bother explaining how to use things here; It's very possible this entire project could disappear one day.

+# 02_led-button-web
+
+This example is largely adapted from those in [ESP32-basic-starter-kit.pdf](./ESP32-basic-starter-kit.pdf).
+
+The APIs in the original examples paired with this PDF have changed, and I decided to do some different things with the code and/or circuits, but the original code can be [found here](https://www.dropbox.com/scl/fo/6znlij3eb23ih4jxcpv2w/AKvB1t9CCUgoVRVtGen8Yrw?rlkey=z84anl0hs940qf9fpl7l8q8q2&e=1&dl=0).
+
+![schematic](./schematic.png)
+
+This example uses the same schematic as [01_led-button](../01_led-button/).
+
+The only difference is that you can also control the button through a web browser from any device connected to your local network.
+
+This example was adapted from the example code in the [Arduino ESP32 API reference](https://docs.espressif.com/projects/arduino-esp32/en/latest/api/wifi.html#wi-fi-ap-example).
