+### Partial wildcard redirects
+
+Use partial wildcards to match URL segments that start with a specific prefix.
+
+```json
+"redirects": [
+  {
+    "source": "/articles/concepts-*",
+    "destination": "/collections/overview"
+  }
+]
+```
+
+This matches any URLs with the `/articles/concepts-` path, such as `/articles/concepts-getting-started` and `/articles/concepts-overview`, and redirects them all to `/collections/overview`.
+
+You can also substitute the captured wildcard value in the destination.
+
+```json
+"redirects": [
+  {
+    "source": "/old/article-*",
+    "destination": "/new/article-*"
+  }
+]
+```
+
+This redirects `/old/article-123` to `/new/article-123`, preserving the captured value after the prefix.
+
+### Avoid infinite redirects
+
+To avoid infinite loops, the destination slug cannot match the source slug. For example, if your docs are hosted at `/docs`, avoid:
+
+```json
+"redirects": [
   {
     "source": "/docs/:slug*",
     "destination": "/:slug*"
