Crafting Effective READMEs

Overview

READMEs answer questions your audience will have. Different audiences need different information - a contributor to an OSS project needs different context than future-you opening a config folder.

Always ask: Who will read this, and what do they need to know?

Process

Step 1: Identify the Task

Ask: "What README task are you working on?"

Task When
Creating New project, no README yet
Adding Need to document something new
Updating Capabilities changed, content is stale
Reviewing Checking if README is still accurate
Step 2: Task-Specific Questions

Creating initial README:

  1. What type of project? (see Project Types below)
  2. What problem does this solve in one sentence?
  3. What's the quickest path to "it works"?
  4. Anything notable to highlight?

Adding a section:

  1. What needs documenting?
  2. Where should it go in the existing structure?
  3. Who needs this info most?

Updating existing content:

  1. What changed?
  2. Read current README, identify stale sections
  3. Propose specific edits

Reviewing/refreshing:

  1. Read current README
  2. Check against actual project state (package.json, main files, etc.)
  3. Flag outdated sections
  4. Update "Last reviewed" date if present
Step 3: Always Ask

After drafting, ask: "Anything else to highlight or include that I might have missed?"

Project Types

Type Audience Key Sections Template
Open Source Contributors, users worldwide Install, Usage, Contributing, License templates/oss.md
Personal Future you, portfolio viewers What it does, Tech stack, Learnings templates/personal.md
Internal Teammates, new hires Setup, Architecture, Runbooks templates/internal.md
Config Future you (confused) What's here, Why, How to extend, Gotchas templates/xdg-config.md

Ask the user if unclear. Don't assume OSS defaults for everything.

Essential Sections (All Types)

Every README needs at minimum:

  1. Name - Self-explanatory title
  2. Description - What + why in 1-2 sentences
  3. Usage - How to use it (examples help)

References

  • style-guide.md - Common README mistakes and prose guidance
