Questions & Answers

Q: How can you master 80% of Obsidian in 15 minutes?

Focus on three essentials: capturing ideas with near-zero friction, connecting them through links and backlinks, and keeping them in an offline, local-first format. Start with a simple vault and collection of notes instead of trying to use every plugin, theme, folder, and metadata feature at once.

Q: What is an Obsidian vault?

An Obsidian vault is a folder of notes stored on your computer. Each note is an individual Markdown text file that can also be opened in other Markdown-compatible apps.

Q: How do you create and organize notes in Obsidian?

After creating a vault, use the left sidebar to make a new note or folder. You can sort notes by file name or modified time, automatically reveal the open file, expand or collapse folders, and search across the entire vault.

Q: How do you link notes in Obsidian?

Type two left brackets and begin entering the name of the note you want to link, then close the link with two right brackets. You can also highlight existing text and press the left bracket twice to turn that text into a link.

Q: Can Obsidian link to notes that have not been created yet?

Yes. Placeholder links appear in searches and graph view even before their notes are created. To create the linked note, Command-click it on Mac or Control-click it on Windows.

Q: What are backlinks in Obsidian?

Backlinks show every mention that links to the active note. The backlinks area in the bottom right lets you collapse linked mentions or expand them to see the surrounding text.

Q: How can you sync Obsidian across devices?

You can connect an Obsidian vault to a cloud storage service such as Dropbox or use Obsidian Sync. Obsidian Sync is a paid official service that provides end-to-end encryption and version history for vaults.

Q: Which Obsidian setting helps prevent broken internal links?

Open Settings, go to Files and Links, and enable Automatically update internal links. When you rename a note, Obsidian will then update links to that note automatically.

Q: What Obsidian mistakes should beginners avoid?

Beginners should avoid importing all their old notes, installing complex plugins on day one, and organizing knowledge into too many folders. Start fresh, focus on linking your own thoughts, keep ideas in broad buckets until patterns emerge, and learn hotkeys early.

Q: How do you stop attachments from cluttering the Obsidian sidebar?

Change the default folder for attachments to a dedicated attachments folder. This keeps new images and other documents from cluttering the sidebar.

Q: What are the essential Obsidian Markdown shortcuts?

Use Command-B for bold and Command-I for italics on Mac, or Control-B and Control-I on Windows. You can also use pound symbols for headings, two tildes for strikethrough, two equal signs for highlighting, a greater-than sign for quote blocks, dashes for bullet lists, and double brackets for links to notes.

Summary & Key Takeaways

  • Obsidian is a versatile note-taking app that emphasizes linking ideas through backlinks, allowing users to create a network of interconnected notes. It uses Markdown, ensuring that notes remain accessible even if the app disappears. Users can sync data across devices using cloud services like Dropbox or Obsidian Sync, which offers end-to-end encryption.

  • Customization is a key feature of Obsidian, with numerous plugins and themes available to enhance its functionality. However, it is important to start with a simple setup to prevent becoming overwhelmed by the app's capabilities. Users are advised to focus on linking their thoughts and gradually incorporate plugins and themes.

  • Efficient use of Obsidian involves learning hotkeys and shortcuts, which can significantly speed up note-taking and organization. Although Obsidian does not have built-in AI, users can integrate third-party AI tools to enhance their workflow. Organizing notes with a simple folder structure and using maps of content is recommended for effective information management.
