+## Specification
+A squad of robotic rovers is to be landed by NASA on a plateau on Mars.
+This plateau, which is curiously rectangular, must be navigated by the rovers so that their on
+board cameras can get a complete view of the surrounding terrain to send back to Earth.
+A rover's position is represented by a combination of an x and y co-ordinates and a letter
+representing one of the four cardinal compass points. The plateau is divided up into a grid to
+simplify navigation. An example position might be 0, 0, N, which means the rover is in the
+bottom left corner and facing North.
+In order to control a rover, NASA sends a simple string of letters. The possible letters are 'L', 'R'
+and 'M'. 'L' and 'R' makes the rover spin 90 degrees left or right respectively, without moving
+from its current spot.
+'M' means move forward one grid point, and maintain the same heading.
+Assume that the square directly North from (x, y) is (x, y+1).
+\
+\
+**Input:**\
+The first line of input is the upper-right coordinates of the plateau, the lower-left coordinates are
+assumed to be 0,0.
+The rest of the input is information pertaining to the rovers that have been deployed. Each rover
+has two lines of input. The first line gives the rover's position, and the second line is a series of
+instructions telling the rover how to explore the plateau.
+The position is made up of two integers and a letter separated by spaces, corresponding to the
+x and y co-ordinates and the rover's orientation.
+Each rover will be finished sequentially, which means that the second rover won't start to move
+until the first one has finished moving.
+\
+\
+**Output:**\
+The output for each rover should be its final co-ordinates and heading

+
+## Requirements:
 - php 8.1
+- Ubuntu. Sorry for this requirement, but I did not use docker\vagrant in this task and did not run on Windows CLI.
 
-# Setup
+## Setup
 1. Run `php composer.phar install`
 
-# Check NASA rovers` position
-To check position of NASA rovers position run command from console: `php bin/console app:nasa-rovers`
+## About command
+To check position of NASA rovers position run command from console: `php bin/console app:nasa-rovers`.
+\
+Command will ask you to write top-right coordinates (`5 5` for example) and then will ask to write rovers start positions and lists of actions.
+\
+To finish enter rovers information you should press `Ctrl+D` buttons combination.
+
+## About tests
+To run tests use composer command: `php composer.phar tests`
