+Inserts specified values at the head of the list stored at `key`, only if `key`
+already exists and holds a list. In contrary to `LPUSH`, no operation will be
+performed when `key` does not yet exist.
+
+@return
+
+@integer-reply: the length of the list after the push operation.
+
+@history
+
+- `>= 4.0`: Accepts multiple `element` arguments. In Redis versions older than
+  4.0 it was possible to push a single value per command.
+
+@examples
+
+```cli
+LPUSH mylist "World"
+LPUSHX mylist "Hello"
+LPUSHX myotherlist "Hello"
+LRANGE mylist 0 -1
+LRANGE myotherlist 0 -1
+```
