+# References
+
+You can create anchors and references to anchors inside of snekdown documents with the following syntax:
+
+
+
+Anchor: `[?KEY]`
+
+
+*renders as*
+
+
+[?TestRef]
+
+
+
+Reference: `[Description](#KEY)` (classic url syntax)
+
+
+*renders as*
+
+
+[Description](#TestRef)
+
+
+
+Anchors don't render in the document but References to anchors do.
+There's currently no validation if a reference is valid so make sure to use the correct keys.
