+# CursorMover Class
+
+The `CursorMover` class is responsible for moving the cursor position in the DynamicCursesInput gem. It provides methods to move the cursor to the left or to the right.
+
+## Methods
+
+### .left(cursor_pos)
+
+This is a class method that moves the cursor one position to the left. It takes one parameter:
+
+- `cursor_pos`: the current cursor position.
+
+If the cursor is already at the start of the line (i.e., `cursor_pos` is zero), it does not change the cursor position. Otherwise, it decreases the cursor position by 1.
+
+### .right(cursor_pos, length)
+
+This is a class method that moves the cursor one position to the right. It takes two parameters:
+
+- `cursor_pos`: the current cursor position.
+- `length`: the length of the input string.
+
+If the cursor is already at the end of the line (i.e., `cursor_pos` is equal to `length`), it does not change the cursor position. Otherwise, it increases the cursor position by 1.
