Obsidian Tutorial

Obsidian is a personal knowledge base and note management tool based on Markdown files, mainly used for knowledge organization, note-taking, and building a personal knowledge system.

Obsidian uses local file storage. All notes are saved as plain Markdown documents, making them easy to migrate, back up, and manage long-term.

The biggest difference between Obsidian and traditional note-taking software is not that it can take notes, but that it turns notes into a connectable, extensible, and computable knowledge network.

Why Use Obsidian

Most people encounter a problem during learning: they learn many things, but after a while they forget, or they know they wrote it down but can't find it.

Ordinary note-taking software is usually just an information warehouse, whereas Obsidian is more like a knowledge hub.

Obsidian's core idea is:Connect scattered notes and let knowledge grow on its own.

What Can Obsidian Bring?

Capability	Description
Knowledge Linking	Automatically establish relationships between knowledge through bidirectional links.
Local Storage	All notes are plain Markdown files, not dependent on cloud databases.
Knowledge Graph	Automatically generate a knowledge relationship network diagram.
Plugin Extensions	Supports plugins such as calendar, task management, AI, Git, mind mapping, and more.
Cross-platform	Supports Windows, macOS, Linux, Android, and iOS.

Common Problems with Regular Note-Taking Software

After recording a large amount of content, many people experience:

They have bookmarked many articles but cannot find them.
Knowledge points become more numerous and more chaotic.
They repeatedly record the same content.
Things they have written cannot be reused.
There are more and more notes, but knowledge does not grow.

Obsidian's goal is not to make you write more, but to make you connect more.

Who Should Learn It?

Not everyone needs Obsidian; it is better suited for people who accumulate knowledge long-term and engage in continuous learning.

User Type	Use Cases
Programmers	Technical notes, code snippets, project documentation
Students	Course organization, postgraduate entrance exams, knowledge review
Writers	Material management, article creation, inspiration collection
Researchers	Paper management, reference organization
Intensive Learners	Build a long-term personal knowledge base

Who Is Less Suitable

Only want to record temporary matters.
Only write to-do items.
Do not like configuring software.
Want real-time multi-person collaboration.
