Field Notes: a project reading kit

A fictional project for a small team building a local field-notes app. These files are reading examples, not a real customer story or a working application.

Start with the question

Can a researcher collect notes without an internet connection, then hand a readable summary to a colleague?

Read nextQuestion it answers
Specification (local file)What does the first version need to do?
Architecture (local file)How are the parts connected?
Implementation plan (local file)What work is proposed?
Decisions (local file)Why choose ordinary local files?
Release notes (local file)What changed in this example?

  1. Read the specification's scope.

  2. Follow its architecture link.

  3. Open the local-files decision.

  4. Return to the specification and check the acceptance criteria.

What this kit is for

Use the same folder in a text editor, a browser preview, or a Markdown reader. Keep the files together so their relative links resolve. No scripts or installer are included.

This browser reader supports headings, lists, tables, links, task lists, code and footnotes. Mermaid and math stay as source here. Images are not loaded; local file links need the downloaded folder. Raw HTML is displayed as text. Text is kept only in this tab; download a copy before leaving. Maximum file size: 1 MB.

How to open a .md file online

  1. Open or paste. Choose Open .md file and pick a Markdown file, or paste Markdown into the source pane. You can also start from one of the sample documents.
  2. Read the rendered page. Headings, lists, tables, code and links appear formatted on the right. Use the outline to jump to a heading and Find in document to search.
  3. Keep a copy. Edit the source if you need to, then use Download .md or Copy Markdown. Print saves the page as a PDF from your browser.

WHEN ONE FILE BECOMES A PROJECT

Keep the whole folder in view.

This page reads one file. Aero Markdown for Mac reads the whole folder: follow links between documents, see Mermaid diagrams and math rendered, and keep your place when a coding agent updates the file. The Mac app is not available to download yet.

About this online reader

Are my documents uploaded?

No. Parsing and rendering happen in this browser tab. The tool does not load document images or run embedded HTML. Following an external link is an explicit action that opens that site.

Can I keep my changes?

Use Download .md to save a copy, or Copy Markdown. The original file is not overwritten. Closing or reloading the tab loses text you have not saved.

Does it render diagrams and math?

This web version shows Mermaid and math as source. The Mac reader includes its own diagram and math rendering. See the Mermaid guide for an example.
