# Lists
Markdown supports ordered lists and unordered lists.   
---
# Unordered Lists  
Use asterisk `*` , plus sign `+` or hyphen `-` as markers. Add a space after the marker before writing content.  
- item
- item
- item

# Ordered Lists
Ordered lists are used to display steps or items that require a specific sequence.  
To create an ordered list, use a number followed by a period. Example:  
1. First item
2. Second item
3. Third item

### Non-consecutive numbers
Markdown will automatically reorder the items even if the numbers are not consecutive:  
`1. First item  
3. Second item (displayed as 2)  
7. Third item (displayed as 3)`  

1. First item  
3. Second item (displayed as 2)  
7. Third item (displayed as 3)

### Start from a specified number
5. Fifth item
6. Sixth item
7. Seventh item

# Nested Lists
Lists support nesting to build multi-level structures.

### Nested Unordered Lists
- Fruits
  - Apple
    - Red apple
    - Green apple
  - Banana
  - Orange
- Vegetables
  - Carrot
  - Chinese cabbage

### Nested Ordered Lists
1. Preparation
   1. Collect materials
   2. Make a plan
2. Implementation
   1. Start execution
   2. Monitor progress
3. Summary

### Mixed Nesting
1. Main tasks
   - Subtask A
   - Subtask B
     1. Step 1
     2. Step 2
   - Subtask C
2. Minor tasks

Add 2 or 4 spaces before sub-list items to realize mixed nesting:
1. First item:
    - First nested element
    - Second nested element
2. Second item:
    - First nested element
    - Second nested element

### Nesting Rules
- Indent sub-lists with 2 to 4 spaces (2 spaces recommended)
- Keep the indentation consistent
- Nesting can be unlimited, but it is recommended to use no more than 3 levels in practice
