+
+### Objectives
+
+Develop a program that receives only one argument, a text file which will contain a list of [Tetrominoes](https://en.wikipedia.org/wiki/Tetromino) to assemble them in order to create the smallest square possible.
+
+### Instructions
+
+- Your program will be tested using our solution, you don't need to submit your text files
+
+The program must :
+
+- Expect at least 2 Tetrominoes in the text file
+- Identify each Tetromino in the solution, by assigning different letters to different Tetrominoes
+- Assemble all of the Tetrominoes in order to create the smallest square possible
+- Print the solution where Tetrominoes are placed on their most upper left position, if there are more than one solution it
+- In case of bad format on the Tetrominoes or bad file format it should print `ERROR`
+
+#### Example of a text File
+
+```console
+#...
+#...
+#...
+#...
+
+....
+....
+..##
+..##
+```
+
+- If it isn't possible to form a complete square, the program should leave spaces between the Tetrominoes. For example:
+
+```console
+ABB.
+ABB.
+A...
+A...
+```
+
