Obsidian and Markdown Beginner Guides

Source: shared Gemini conversation (Flash, published 5 Sep 2026) — Gemini share. For my son — a simple starting point for anyone new to Markdown and Obsidian.

YouTube video embeds are enabled by pasting the link with a ! prefix (![…](url)) so Obsidian renders them inline.

  • Clear, step-by-step guide for absolute beginners: downloading the app, creating a vault, and essential Markdown formatting (headings, lists, bold/italics, internal links) built around a practical project.
  • Focuses on demystifying Markdown syntax inside Obsidian — how #, *, and [[]] translate raw text into clean, formatted notes.
  • PKM-focused and trusted in the community. Keeps it simple — start writing plain text rather than fussing over themes and plugins early on.
  • The fourth video (detailed below): note-taking fundamentals, then three levels of AI integration — AI second brain, AI-as-database, and full LLM-wiki automation.

(Corrected 2026-09-29: the list showed three videos while the sections below ran to four.)

Key concepts to watch for

  • Headings: # Heading / ## Heading (hash followed by space).
  • Links: Internal links use double square brackets → [[Note Name]].
  • Live Preview: Obsidian’s default mode hides Markdown symbols when the cursor moves away, showing formatted text while keeping the file as plain, future-proof text.

Main learning objectives (as provided by Gemini)

Video 1 — Kevin Stratvert, “Obsidian Tutorial for Beginners”

Core Obsidian setup & navigation

  • Vault Creation — what a vault is (a plain local folder) and creating one from scratch.
  • Workspace Interface — left sidebar file explorer, main editor, graph view.

Essential Markdown formatting

  • Structural headings with #, plus collapsing/expanding sections.
  • Checklists (- [ ]), bullet lists, and numbered lists.
  • Text styling & media — italics, embedding images/media in notes.

PKM foundations

  • Internal linking (wiki-links) with [[Note]] to build connected note networks.
  • Graph view to visualise connections across the vault.
  • Vault search across all note contents.

Advanced ecosystem features

  • AI integration — local Markdown storage lets desktop AI assistants search/ summarise within the vault.
  • Plugins — enabling core and community plugins.
  • Syncing & backups — Obsidian Sync or local cloud folders.

Video 2 — Mike Schmitz, “Obsidian Markdown Made Ridiculously Simple”

Plain text & core syntax

  • Why Obsidian uses plain-text files, how markup renders, and the benefit of future-proof data ownership.
  • Heading hierarchy, bold/italics/strikethrough/inline highlight, and list types.

Links, callouts & structured formatting

  • Internal and external linking.
  • Callout boxes / blockquotes (e.g. > [!INFO]), code blocks, and tables.

Productivity tips

  • Command palette and hotkeys; Live Preview mode; common mistakes to avoid (over-complicating, focusing on formatting over ideas).

Video 3 -Tina Huang in 24 minutes

This video provides a comprehensive guide to using Obsidian as a powerful tool for building AI-integrated knowledge systems. The creator covers the app’s fundamental note-taking features, followed by three distinct levels of AI integration:

  • Fundamentals of Obsidian (1:19 - 6:39): Explains how Obsidian uses local Markdown files, note-linking, and graph visualization to create a flexible, searchable vault.
  • Level 1: AI Second Brain (6:39 - 12:22): Involves pointing an AI (like Claude or Codeex) at your vault to retrieve, interpret, and analyze your existing notes.
  • Level 2: AI Database (12:22 - 16:30): Shifts the workflow so that AI agents (like Lifebot or Tacobot) actively write logs, health data, and documentation into your vault, functioning as an automated database.
  • Level 3: LLM Wiki (16:30 - 24:15): The most advanced approach, where AI completely manages the wiki infrastructure—ingesting sources, maintaining indexes, and performing health checks—with the human acting as an observer.

Throughout the video, the creator emphasizes how Obsidian’s structure as a local folder of files makes it uniquely compatible with these automation patterns.

What is NOT covered by these videos

None of these videos goes into the following in detail — worth learning separately, especially since the family vault relies on them:

  • Attachment folder config — by default pasting an image drops it into the vault root, creating clutter. Fix: Settings → Files and links → set Default location for new attachments to a dedicated folder (e.g. assets).
  • Frontmatter / YAML metadata — structured metadata at the top of a note (delimited by ---, written as key-value pairs). Example: 
    ---
title: Note Title
date: 2026-09-05
tags:
  - project
status: active
---
    Modern Obsidian renders this as a Properties table at the top of the editor.
  • Tags — #tag (no space) to classify and filter across the vault; nested tags like #status/done. Clicking a tag opens global search for every note with it.

Vault-specific note (Alf): the family alf-vault already uses frontmatter and public: flags on every note (default public: false; only the owner sets a note public). Anyone new to Obsidian here should read the vault conventions alongside these videos.
