+## DEPRECATION NOTICE
+
+Sorry this project is not actively maintained anymore! 😢 Please consider migrating to one of the alternatives listed below.
+
+### Alternatives
+
+- [muffet](https://github.com/raviqqe/muffet)
+  - Fast website link checker in Go
+- [lychee](https://github.com/lycheeverse/lychee)
+  - A glorious link checker
+  - This tool supports testing links both in local files and on websites.
+- [hyperlink](https://github.com/untitaker/hyperlink)
+  - Checks folder of HTML for relative/internal links (no markdown or external websites)
+
+### Why is it not maintained anymore?
+
+It's because we found several problems with the goals of the project and the amount of work it needs.
+
+The goal of this software was originally to check links in Markdown files which are **compiled into HTML files and served via HTTP servers**. But that raises the following problems.
+
+- We cannot test links which do not exist in the Markdown files.
+  - For example, some markdown-based static site generators generate links at compile time.
+  - e.g. automatic generation of table of contents
+- We cannot test the behaviour of HTTP servers.
+  - Different HTTP servers handles URLs differently.
+  - e.g. trailing slashes, inference of page file extensions, ...
+
+It needs a lot of work to support all these different use cases. In short, we need to emulate different Markdown file compilers and HTTP servers as well as web browsers.
+
+### But I still want this...
+
+If you think this software is still valuable for you even in comparison with the alternatives listed above and want it to be maintained, please let us know by posting a new issue.
