Zettelkasten for Beginners: A Simple Markdown Workflow

The Zettelkasten (“slip box”) method is a way of taking notes as small, single-idea notes that link to each other, so a web of ideas grows over time. It was popularized by the German sociologist Niklas Luhmann, who is widely reported to have kept a large collection of linked paper slips and to have credited it as a partner in his writing. You do not need his scale or his paper. This guide shows a simple version you can run in any markdown notes app that supports wiki links and backlinks.

The core idea in one paragraph

Write one idea per note, in your own words, with a clear title. Link each new note to at least one existing note. Let the links, not folders, carry the structure. When you later need to write something, you start from the notes and follow the connections instead of starting from a blank page.

The three kinds of notes

• Fleeting notes: quick captures you will process later. They are rough and temporary.
• Literature notes: ideas from things you read, in your own words, with a reference to the source.
• Permanent notes: a single, well-formed idea that makes sense on its own, written so that you could understand it a year from now.

Fleeting and literature notes are inputs. Permanent notes are the real product, and they are the ones you link densely.

A simple markdown setup

1. Capture fleeting notes with a quick shortcut (Cmd+N in atiea) and tag them #inbox.
2. Once a day, turn the useful ones into permanent notes with a clear title. Delete the rest.
3. Link each permanent note to at least one other with [[wiki links]].
4. Use backlinks to find connections you forgot.

A sample note set

Here is what the three note types might look like in plain markdown. The topic is invented, but the shape is realistic.

# Inbox: spaced repetition thought   #inbox

Maybe reviewing notes is more useful than rereading books?
Check the article I saved.

# Literature: Notes on memory (article)   #literature

Source: an article on how memory works, read this week.
- Recalling something strengthens it more than rereading it.
- Gaps between reviews help retention.

# Retrieval beats rereading   #learning

Trying to recall an idea from memory does more for retention than
passing your eyes over it again. This is why I write notes in my
own words and revisit them without looking at the source.

Source: [[Literature: Notes on memory (article)]]

# Write in your own words   #learning

Copying a quote lets me skip the understanding. Rewriting forces me
to find out whether I understood it. See [[Retrieval beats rereading]].

Two things to notice. First, the permanent note states one claim in its title and explains it in a few sentences. Second, it links both to the source and to neighboring ideas, so the backlinks on “Write in your own words” will show “Retrieval beats rereading” without you maintaining anything.

A step-by-step weekly routine

1. Capture all week. Use Cmd+N and jot fragments. Tag them #inbox. Do not organize at this stage.
2. Process daily or every few days. Open the #inbox tag. For each fleeting note, either delete it, fold it into an existing note, or rewrite it as a permanent note.
3. Write literature notes as you read. Keep them short and in your own words, and name the source at the top.
4. Link as you write. Before you finish a permanent note, ask “what existing note does this relate to?” and add at least one [[link]] with a sentence of context.
5. Review once a week. Open two or three notes and read their backlinks. Add one link you missed. Merge any two notes that say the same thing.
6. Write from the notes. When you have an essay, project or decision to work on, gather the linked notes first and outline from them.

How to write a good permanent note

• Title as a claim. “Retrieval beats rereading” is more useful than “Memory”.
• One idea. If you need the word “and” to describe the note, consider splitting it.
• Your own words. This is where the thinking happens.
• Self-contained. Someone, including future you, should understand it without opening the source.
• Connected. At least one link, and a reason for it.

Do you need a special app?

No. You need quick capture, wiki links, backlinks and tags. A calm app helps because the method works best when writing feels effortless. atiea offers that set: a native Mac markdown editor with [[wiki links]], backlinks, inline #tags, pinned notes and a quick new-note shortcut. Notes stay on your Mac, with no account needed, and you can export to Markdown, HTML, PDF or DOCX. See the features page for the full list.

Other tools can run the same method. If you are weighing options, compare them in best markdown notes app for Mac or the Obsidian alternative page, and check each product’s site for current details.

Common mistakes

• Collecting without connecting. Links are the point. A pile of unlinked notes is just a bigger inbox.
• Notes that are too long. One idea per note.
• Copying instead of rephrasing. Pasted quotes feel productive but skip the understanding.
• Over-engineering tags and numbering. A few broad tags plus links is enough to start. Elaborate systems tend to be abandoned.
• Never processing the inbox. If #inbox grows for weeks, shrink your capture habit or schedule a fixed processing time.
• Chasing the perfect structure first. Begin with ten notes and see how you use them.

Troubleshooting

• “I have notes but no connections.” Open an old note and write one sentence about how it relates to something new. Add the link.
• “Everything links to one hub note.” Split the hub into narrower notes and link to those instead.
• “I cannot find things.” Use find (Cmd+F) for text, tags for topics and backlinks for relationships. Pin the few notes you open every day.
• “It feels like homework.” Reduce scope. Capture less, process only what mattered, and skip the weekly review for a while.

When not to use Zettelkasten

The method suits ideas you want to build on: study, research, writing and long-running projects. It is overkill for grocery lists, one-off meeting notes or reference material you only look up. It also takes steady, small effort. If you want a project tracker, a database or a shared team space, a different type of tool will serve you better. For plain everyday notes, the guide to taking notes in markdown may be all you need, and the glossary explains any terms that are new.
