+
+Lychee can check Wikilinks in Markdown files as long as they provide a path to the linked ressource.
+
+```markdown
+# ✅ Good - links can be checked
+
+[[https://example.com/docs/]]
+[[./another/markdown/file.md]]
+
+# ❌ Bad - Will not work
+
+[[another-markdown-page]]
+```
+
+Tools like e.g. [Obsidian](https://obsidian.md/) use the second (bad) form of link, using only the file name without path or file extension.
+
+Lychee has no possibility of determining the correct path for this file as it could be:
+
+- in the same directory
+- in a subdirectory
+- in a parent directory
+
+A recursive search of all those options is currently not supported.
