#Theme Notes

Theme notes are the basic unit of LifeOS. Every topic in your life and work -- whether it's a project with a deadline, an area requiring ongoing attention, or a topic you're interested in -- can be managed as a theme.

#Understanding Theme Notes

Each theme note has a unique theme tag as its identifier. Tag any note with this theme tag, and related tasks, bullets, and files are automatically collected in the theme note's index file.

This is the core of LifeOS's "low-pressure recording": just jot things down in your daily notes with a tag, and you can find all related content in the theme note later.

#PARA Directory Structure

LifeOS uses the PARA method by default to organize theme notes. Here is the actual directory structure from the example vault:

Vault/
├── -1. 捕获/          # Unsorted temporary content
│   ├── 2024 新年建议 - 陈思远.md
│   ├── 不理解超线性回报，就无法理解这个世界.md

#PARA Four-Category Overview

Additionally, there are two auxiliary directories:

• -1. Capture -- Unsorted temporary content; capture first, organize later
• 5. Expression -- Output refined from resources and areas

#Theme Note Templates

Each category directory has a Template.md that is automatically used when creating new theme notes.

#Project Template

%%设置项目截止日期，及其结果描述%%

- [ ] #<% tp.frontmatter.tags %> 📅 <% tp.date.now("YYYY-MM-DD", 7) %>
- 结果描述

## 任务

%%根据当前文件的 Properties 的 tags 字段查询任务，从所有的笔记中提取%%

```LifeOS
TaskListByTag
```

## 闪念

%%根据当前文件的 Properties 的 tags 字段查询子弹列表，从所有的笔记中提取%%

```LifeOS
BulletListByTag
```

## 文件

%%根据当前文件的 Properties 的 tags 字段查询文件列表，从所有的笔记中提取%%

```LifeOS
FileListByTag
```

Each theme note automatically indexes via three LifeOS code blocks:

#Area Template

## 归档

%%本领域归档的项目列表%%

```LifeOS
ArchiveListByTag
```

## 任务

%%根据当前文件的 Properties 的 tags 字段查询任务，从所有的笔记中提取%%

```LifeOS
TaskListByTag
```

## 闪念

%%根据当前文件的 Properties 的 tags 字段查询子弹列表，从所有的笔记中提取%%

```LifeOS
BulletListByTag
```

## 文件

%%根据当前文件的 Properties 的 tags 字段查询文件列表，从所有的笔记中提取%%

```LifeOS
FileListByTag
```

The area template adds ArchiveListByTag to display archived projects under that area.

#Create a Theme Note

1. Switch to "Theme Notes" in the top-left form
2. Enter a theme tag (e.g., 个人品牌/WOT-分享会)
3. Select the target category (Project/Area/Resource)
4. An index file is auto-created with template content pre-filled

#Manage Note Lifecycle

PARA's core principle is "actionability" -- note categories change over time:

#When a Project Completes

1. Confirm all tasks in the project are done
2. Move the entire project folder to 4. 存档/
3. The project disappears from the home view but remains searchable

#Periodic Review

Spend 15 minutes monthly reviewing your PARA:

• Are there completed projects that haven't been archived?
• Should any areas be downgraded to resources?
• Have any resources actually become active projects?

#Use "Flash Roaming"

Click the "Flash Roaming" button and Aino LifeOS randomly surfaces your historical notes -- helping you rediscover forgotten ideas and spark new connections.
