+<h3> <a href="https://github.com/LukeProducts/AStar-Pathfinding-Cpp/blob/main/AStar.hpp#L454-L480">readmaze</a> - function </h3>
+
+readmaze reads in a maze from the consoles cin stream, <br>
+the first line must consist of two integers that indicate the height and width of the mazes to be read in. <br>
+In the following you can pass in the maze like this: <br>
+
+```
+    10 10        // first 10 = m = rows, second 10 = n = columns
+    ##########
+    #        #
+    # ##### ##
+    # ##    ##
+    # ##  ####
+    # ###    #
+    #  #  ## #
+    ###  ##  #
+    ##  ##  ##
+    ##########
+
+```
+readmaze converts this directly to the maze format by calling the prepare_maze - function, <br>
+which Astar() needs, <br>
+so in the one with ones and zeros:
+```
+    1111111111
+    1000000001
+    1011111011
+    1011000011
+    1011001111
+    1011100001
+    1001001101
+    1110011001
+    1100110011
+    1111111111
+```
+
+so you can pass in the return value vector\<vector\<int>> directly into the AStar - function:

+https://github.com/LukeProducts/AStar-Pathfinding-Cpp/blob/main/examples/readmaze.cpp#L10-L16
+
+the disatvantage here is, that because readmaze converts the ascii maze into a numeric one at one time, <br>
+you must know the start and end position before, <br>
+you would hardcode them, <br>
+but that's probably not, what you want. <br><br>
+So theres the pardon readunpreparedmaze presented in the following.
