+# Usage
+
+* Embed struct rb\\_node into your data structure
+* There's no callback for comparison, write your own lookup and insertion
+  functions
+* Locking is up to the user
+
+# API
+
+* rb\\_entry is the same as container\\_of
+* Create the root with struct rb\\_root name = RB\\_ROOT;
+* Lookup function (see example) uses rb\\_left and rb\\_right members
+* Insertion: lookup insertion point, save the parent and use the functions
+  rb\\_link\\_node and rb\\_insert\\_color (example in Documentation)
+* Erase with rb\\_erase
+* Iterate with functions rb\\_first, rb\\_last, rb\\_next and rb\\_prev
+
+# Hashes
+
+* No hash table
+* There are hash functions found at
+       - include linux/hash.h
+       - include linux/jhash.h
+* Users usually do chaining to resolve collisions
