 4 |   How does it work?
 5 |   When a player attacks another player he uses 3 dices, the red is always the attacker and the blue is the defender.
 6 | 
 7 |   You have to compare the dice with the highest number to simulate the fight.
 8 |   N = first highest number
 9 |   M = second highest number
10 |   O = third highest number
11 | 
12 |   If the numbers are equal, the defensor (blue) wins.

 1 | # git-course-exercises
 2 | 
 3 | ### 1️⃣ How to start
 4 | 
 5 | Fork this repository and clone your fork into your machine using:
 6 | ```bash
 7 | git clone git@github.com:USERNAME/git-course-exercises.git
 8 | ```
 9 | 
10 | enter to your project directory using:
11 | ```bash
12 | cd git-course-exercises
13 | ```
14 | 
15 | ---
16 | 
17 | ### 2️⃣ How to make a branch
18 | 
19 | To create a new `branch` from the main repository and work on a specific exercise (ex. `file.cpp`) you can use the following commands:
20 | ```bash
21 | git checkout main
22 | 
23 | git checkout -b new-branch-name
24 | ```
25 | 
26 | ---
27 | 
28 | ### 3️⃣ How to make a commit
29 | 
30 | From this step you can edit your `file.cpp` and make some commits using:
31 | ```bash
32 | git add exercises/file.cpp
33 | 
34 | git commit -m 'feat: description'
35 | ```
36 | Use the [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/) when you write a commit description.
37 | 
38 | ---
39 | 
40 | ### 4️⃣ How to make a PR
41 | 
42 | Push the commits into GitHub using:
43 | ```bash
44 | git push -u origin new-branch-name
45 | ```
46 | 
47 | Afterward, it is possible to create a Pull Request by going to your fork `https://github.com/USERNAME/git-course-exercises.git` clicking on "create Pull Request" or going to the right section "Pull Request" -> "New Pull Request".
48 | 
49 | If you want to work on another `file.cpp`, go to step 2️⃣.
50 | 
51 | ---
52 | 
53 | Use git wisely.
54 | 
55 | ### Clean code
56 | 
57 | Check [this article](https://testdriven.io/blog/clean-code-python/) to understand how to write "clean code" in python.
