+Removes the first `count` occurrences of elements equal to `element` from the
+list stored at `key`. The `count` argument influences the operation in the
+following ways:
+
+- `count > 0`: Remove elements equal to `element` moving from head to tail.
+- `count < 0`: Remove elements equal to `element` moving from tail to head.
+- `count = 0`: Remove all elements equal to `element`.
+
+For example, `LREM list -2 "hello"` will remove the last two occurrences of
+`"hello"` in the list stored at `list`.
+
+Note that non-existing keys are treated like empty lists, so when `key` does not
+exist, the command will always return `0`.
+
+@return
+
+@integer-reply: the number of removed elements.
+
+@examples
+
+```cli
+RPUSH mylist "hello"
+RPUSH mylist "hello"
+RPUSH mylist "foo"
+RPUSH mylist "hello"
+LREM mylist -2 "hello"
+LRANGE mylist 0 -1
+```
