 ## How algorithm works
-At the beginning, all the pictures that will participate in the rating are assigned numbers, after which they are displayed in turn, two pieces on the screen.
-You are given 2 pictures to choose from and you choose the one that you liked the most, after which its rating increases.
+At the beginning, all pictures participating in the rating system are assigned an initial rating, and variables are also declared for the subsequent random display of pictures out of order.
+```javascript
+var min = 1;
+var max = 18;
+var rb = Math.random() >= 0.5;
+var random = Math.floor(Math.random() * (+max - +min)) + +min;
+var rdm2 = Math.floor(Math.random() * (+mee - +mss)) + +mss;
+```
+All the pictures that will participate in the rating are assigned numbers, after which they are displayed in turn, two pieces on the screen.
+You choose either the left or the right picture and you choose the one that you liked the most, after which its rating increases.
+```javascript
+function go_left(){ ... }
+function go_right(){ ... }
+```
 When pressed, the next pair is immediately displayed, and when all pairs have passed, they begin to be displayed in random order, thereby mixing them together.
+
 Also, by pressing the button, you can display a table with ratings of all guitars on the screen.
+```javascript
+function showRating(){ ... }
+```
