Obsidian getting started | Obsidian For Beginners (1/10)

Obsidian’s biggest practical advantage is that it turns your notes into future-proof plain-text files while also making ideas easy to connect—so learning and reviewing can happen faster without getting trapped in a single app or database. The setup starts with creating a “vault,” which is simply a folder where all notes live. From there, writing a note is straightforward: create a new note, name it, and Obsidian stores it as a .md file that any text editor can open. That plain-text design matters because it avoids the common failure mode of cloud or database-based note apps—years later, if a service shuts down, notes can disappear. With Obsidian, the notes remain under the user’s control and can be accessed as long as the computer (and files) exist.

The workflow then shifts from storing information to actively linking it. When a note includes a double-bracket link (e.g., connecting “How we learn new things” back to “Second Brain”), Obsidian creates a clickable relationship between concepts. Hovering over the link and using a control-click preview lets the user jump into related material instantly, reducing the need to search for terms during review. Even when the linked note doesn’t exist yet, Obsidian creates a gray-violet placeholder, and control-clicking generates the new note automatically—meaning users can build an idea network incrementally without stopping to invent perfect titles upfront.

For people managing large note collections, navigation speed becomes a core feature. Instead of browsing folders or a left sidebar when there are hundreds or thousands of notes, Obsidian supports quick search via Ctrl+O, which opens a search bar to jump directly to a note. The transcript also emphasizes that Obsidian is built for “multimedia notes,” not just text. Users can attach files of essentially any type by copying and pasting or by drag-and-drop. For video, the workflow uses YouTube embed code: paste the embed snippet into a note and the video becomes playable from within the note. PDFs, images, audio, and other assets can be included the same way, enabling richer study and research logs.

Organization is flexible. While folders are the default method, the transcript also mentions using the “Johnny decimal” system as an alternative approach for scaling organization. The graph view is highlighted as another major tool: it visualizes notes as nodes and shows how they connect, letting users open notes by clicking on the graph. Finally, because everything is plain text, syncing isn’t locked to Obsidian’s paid sync. The vault folder can be stored in common cloud services like Google Drive, Dropbox, or OneDrive, then opened from another computer—keeping the same note files accessible across devices without relying on a proprietary database.
