+
+### Procedures
+
+
+### `md5(values)`
+
+Gets the string representation of every element in the input list, concatenates it into a single string, and returns the md5 hash of that string.
+NOTE: The format of string representations can be seen by checking ToString in [CPP API](/memgraph/reference-guide/query-modules/api/cpp-api) documentation for desired type or Value.
+
+#### Input:
+
+- `values: List[Any]` ➡ input list containing elements which can be any of Memgraph's data types.
+
+#### Output:
+
+- `result: string` ➡ resulting md5 hash returned as string.
+
+#### Usage:
+
+NOTE: The hash provided in this documentation will be different from the user's hash for the same input unless the node has the same ID because `Node.ToString()` uses the node's ID in string formation, so different IDs equal different strings, hence, different hashes.
