8## General Principles
9- Code should be **readable, maintainable, and purposeful**.
10- Avoid unnecessary comments. The code should explain itself.
11- Names of variables, methods, and classes should be **clear and semantic**.
12- Methods should be short and perform only **one specific task**.
13 
14## Key Rules
15- **No more than 20 lines per method**.
16- **No more than 2-3 parameters per method**.
17- Use `guard clauses` instead of nested `if-else`.
18- Use value objects instead of multiple parameters.

20## Clean Code Example
21**❌ Bad Code**
22```ruby
23def process_order(order, user, discount, tax)
24  if order && user
25    total = order.total_price - discount + tax
26    user.update_balance(total)
27  else
28    raise 'Error'
29  end
30end
