+# Chrome Dino Game Automation Using Python
+
+## Description
+This python scripts enables chrome dinosaur to play chrome dino game automatically.
+
+
+## Execution 
+* Run `pip install -r requirements.txt` .
+* Run `python coordinates.py` for knowing the cooridnates of your screen.
+* Go to the `chrome://dino` in your Google Chrome Browser.
+* Run `python enemy_location_checker.py` to know the location of cactus and bird (obstacles for dino).
+* Now , Run `python main.py`  
+* Then go to the `chrome://dino` in your Google Chrome Browser and press any key from keyboard to start the game.
+* See how it plays and press a key to interrupt/stop the game.
+
+
+## Features of files
+### Coordinates.py:
+To know the coordinates of screen first we need to find the X and Y locations of screen .
+
+### enemy_location_checker.py:
+To make dino identify the cactus and bird , captured the image of two make a frame of it and trained dino to escape it.
+As , there are only three colors present in this game : black(for night) , white(for day)  and gray(for obstacles and dino)
+So , To match the gray pixels of obstacle to make identify dino for obstacle and if obstacle is close to dino then make a jump. 
+For this take a image with obstacles coming in between using **ImageGrab from pillow library** and then find out the pixels in which the obstacles are coming. 
+
+### main.py
+As game continues, search width has to be increased for bot.For this **time module from python** helps to simulate the dino acceleration.
+Also reverse the loop for dino to get searched from back of screenshot to identify obstacle and it will speed up the program.
+
+
+
+#### All the requirements for this script is mentioned in **requirements.txt** file.
