Complete Obsidian Beginner Tutorial: Building Your Local Knowledge Base

In the AI era, everyone needs their own knowledge base.

Why?

Because AI itself has no stance, no experience, and no aesthetic.

If you ask it a question directly, the answer might be correct but soulless. If you want it to write an article, create a proposal, or organize a recording for you—it will always give you generic, average content that anyone could produce.

What's the difference?

It lies in whether you can feed it your own materials, methodology, experience, and judgment.

With the same model, if you feed it your own content, the output will carry your unique imprint.

This is why from now on, everyone—not just programmers or knowledge workers—should own their own local knowledge base.

And the best solution for a local knowledge base is Obsidian. Here is the overview:

Every layer is a piece of the knowledge base puzzle; missing any part will create a weakness. Let's go through this roadmap layer by layer.

Chapter 1: What is Obsidian?

In one sentence: A local, Markdown-based note-taking software, featuring bi-directional linking and a vast plugin ecosystem.

Three essential differences from ordinary note-taking apps:

Local-first. All notes are .md text files on your computer, independent of any cloud. Even if the Obsidian company goes bankrupt, your notes can still be opened with Notepad.
Bi-directional links. If A links to B, B also knows that A referenced it. Notes are no longer isolated documents but are woven into a web.
Infinite plugin expansion. Thousands of community plugins, from calendar boards to AI integration—basically anything you want exists.

Is it paid? Personal use is completely free. Only "Cloud Sync" and "Online Publishing" are paid services, which beginners don't need.

Who is it for? People with a large volume of notes who want to accumulate knowledge long-term. If you only occasionally record shopping lists, a simple memo app is enough.

Chapter 2: Download and Installation

Go to obsidian.md/download and click the button for your system.

Windows: Download .exe → Double-click to install → Follow the prompts → A purple icon will appear on the desktop.

macOS: Download .dmg → Double-click to open → Drag Obsidian to the Applications folder → Open from Launchpad.

iOS / Android: Search for "Obsidian" in the App Store / Play Store. It's recommended to master the basic usage on a computer first before installing the mobile version.

Creating your first Vault

After launching, it won't be a blank page; it will ask you to create or open a vault.

A Vault is just a regular folder. All the notes you write will be saved inside it.

Operation: Select "Create new vault" → Give it a name (e.g., "My Notes") → Choose a location (Desktop or Documents folder, don't put it deep in the C drive) → Create.

Changing the interface to your preferred language

Settings (bottom left gear) → About → Language → Select your language → Relaunch.

Chapter 3: Interface and Four Core Concepts

Five Main Interface Areas

Leftmost Sidebar: Toolbar with functional icons (Files, Search, Bookmarks, Graph View).
Left Panel: File management area showing all notes and folders in the vault.
Middle Area: Editor where you write notes, supporting multiple tabs.
Right Panel: Auxiliary information like backlinks, outline, and tags. You can ignore this on day one.
Bottom Status Bar: Word count, cursor position. Ignore for now.

Concept 1: Vault

A folder where all notes are stored. Beginners should start with one vault; don't build several at once.

Concept 2: Markdown

A way to format text using plain characters. In Word, you use a toolbar for headings; in Markdown, you just type # followed by a space. There are very few syntax rules, and you'll learn them naturally. Chapter 4 provides a cheatsheet.

Concept 3: Bi-directional Linking (The Core)

Writing [[Note B]] in Note A causes two things to happen:

Note B becomes a clickable link; click it to jump there.
When opening B, the right panel shows a backlink telling you A referenced it.

This is "bi-directional." It makes the connections between notes explicit—the more notes you have, the more valuable this web becomes.

One thing for beginners: Use [[word]] to wrap a word and create a link. If the note doesn't exist, clicking it will automatically create it.

Concept 4: Plugins

Core Plugins: Built-in by the official team; toggle them in settings.
Community Plugins: Made by third parties; install them from the plugin market.

Don't touch community plugins on day one. Use the basic core plugins first, and only search for community ones after a week or two when you find a specific need the native features can't meet.

Chapter 4: Writing Your First Note

Creating a Note

Shortcut Ctrl/Cmd + N, or right-click the file list on the left → New note.

Title it whatever you want, like "Today's Thoughts" or "Reading Notes." Just start writing; don't overthink it.

Markdown Cheatsheet

Heading 1

Heading 2

Heading 3

Bold

Italic

Strikethrough

List item 1
List item 2

Numbered item 1
Numbered item 2

Blockquote

Inline code

python

1def hello():
2    print("Code block")

Bold and Italic can also use Ctrl/Cmd + B and Ctrl/Cmd + I.

Three Editing Modes

Live Preview (Default/Recommended): Symbols are automatically rendered into the final style as you type.
Source Mode: Shows all raw symbols.
Reading Mode: Fully rendered, cannot be edited. Press Ctrl/Cmd + E to toggle between Live Preview and Reading.

Tags and Properties

Tags: Write #ReadingNotes #Habit in the body; clicking a tag aggregates related notes.
Properties (YAML Frontmatter): Written at the very top of a note, wrapped in three dashes, to record structured metadata. Beginners don't need this yet.

Chapter 5: Essential High-Frequency Functions

Files, Search, Bookmarks

File List (Left): Right-click to create notes/folders, drag to move, double-click to open. Don't spend two hours designing folders; just write.
Search (Magnifying glass): Search keywords across all notes—one of your most-used functions.
Bookmarks (Star): Bookmark notes you need to see daily to avoid digging through the file list.

Two Must-Remember Muscle Memories

Ctrl/Cmd + P Command Palette: The universal searcher. If you can't find a function, search here (create, settings, export, run plugins...).
Ctrl/Cmd + O Quick Switcher: Type a note name to open it instantly. Ten times faster than using a mouse.

Graph View

Visualizes the connections between all notes. It's mostly useless when you have few notes, but it becomes stunning once you have hundreds. Beginners can take a look, but don't waste time studying it.

Recommended Settings to Adjust

Editor → Default editing mode → Live Preview.
Files & Links → Default location for new notes → Specify an "Inbox" folder.
Files & Links → Default location for new attachments → Specify a folder like "Attachments" so all pasted images/PDFs go there.
Core Plugins: Ensure Daily Notes, Outline, Bookmarks, Tags, and Templates are enabled.

High-Frequency Shortcuts

View and customize more in Settings → Hotkeys.

Chapter 6: Three Methodologies for Organizing Notes

Core Principle: Keep folders shallow (no more than 1-2 levels). Rely on links and tags for organization. Don't spend hours designing a perfect classification before you've written many notes.

MOC (Map of Content)

Create a "Table of Contents" note that lists other notes on the same topic structurally. It serves as a thematic entry point. You can even have a "Home" note listing all MOCs, forming a "Map of Maps."

PARA

Categorize all notes into four types based on utility:

Projects: Active tasks with a deadline ("Renovating the house").
Areas: Long-term responsibilities without a deadline ("Health," "Finances").
Resources: Interest material library ("Photography," "Python").
Archives: Completed or inactive items.

Zettelkasten (Slip-box)

Three core rules: One idea per note, rephrase in your own words, and actively establish links. The process is "Quick note → Regular organization → Rewrite and link." Best for writers and researchers.

How to choose?

Want to see thematic structure? → MOC
Want to organize by "what I'm doing"? → PARA
Want to accumulate writing material? → Zettelkasten

The best way is to write for half a month and see which need emerges naturally.

Chapter 7: 10 Must-Install Community Plugins

7.1 General Installation Method

Settings → Community Plugins → Turn off Restricted Mode → Browse → Search → Install → Click "Enable" (many people forget this).

7.2 First Batch (Install Immediately)

Calendar — Adds a visual monthly calendar to the right sidebar. Click a date to jump to or create that day's daily note.

Templater (Advanced Templates) — Much more powerful than the core template plugin. It can automatically insert dates, titles, and more.

Image Toolkit — Click an image in a note to pop up a full-screen preview with zoom and drag support.

7.3 Second Batch (Install after a week)

Tasks — Manage tasks scattered across different notes with automated queries.

QuickAdd — Reduces the friction of capturing inspiration. Press a shortcut → type → content is automatically appended to a specific note.

Periodic Notes — Complements daily notes with weekly, monthly, quarterly, and yearly notes.

7.4 Third Batch (Install after two weeks)

Kanban — Create Trello-style boards directly in Obsidian.

Dataview — One of the most powerful plugins. Treat your notes like a database and query them into tables or lists.

Excalidraw — A hand-drawn style whiteboard for mind maps and flowcharts.

Various Complements — Intelligent completion that suggests note titles as you type.

Chapter 8: 10 Practical Scenario Templates

Don't use them all at once; pick 1-2 most useful ones. (Templates for Daily Notes, Inspiration Inbox, Reading Notes, Meeting Notes, To-Do Lists, Project Plans, Knowledge Cards, Bookmarks, Weekly Reviews, and Quick Reference Manuals).

Chapter 9: Importing External Materials

Word: Use the Importer plugin or copy-paste directly.

Feishu: Export as Markdown or Word, then import.

PDF: Drag and drop into the editor. Use ![[filename.pdf]] to embed.

Audio & Video: Supports mp3, wav, mp4, etc. Use ![[file.mp3]] to show a player.

Chapter 10: Integrating AI Large Models

Let AI summarize, translate, rewrite, or answer questions about your notes directly in Obsidian.

Install the Copilot plugin (by Logan Yang). It works with various providers.

Recommended: DeepSeek. It's powerful, cheap, and accessible.

Chapter 11: Sync and Backup

Notes are assets that grow in value; always back them up.

Obsidian Sync (Official/Paid): Easiest and most secure.
Remotely Save / iCloud: Simple but limited.
Obsidian Git: For version history and tech-savvy users.
Syncthing: Free and open-source peer-to-peer sync.

Chapter 12: Learning Rhythm for Beginners

Don't rush. The value of Obsidian accumulates over time.

5 Core Mindsets:

Write first, organize later.
Don't pursue perfect notes.
Develop a habit of linking.
Don't install too many plugins early on.
Don't treat Obsidian as just a collection folder; rephrase in your own words.

Chapter 13: FAQ

(Covers data security, Markdown learning curve, importing from other tools, plugin safety, and organization methods).

Obsidian isn't a tool that shows results instantly; its value grows with time. It doesn't require you to be a programmer; it just requires you to open it every day and write something.

Start today. A diary entry, a thought, or just one sentence.

Accumulate slowly, and Obsidian will become your ultimate arsenal.
