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 Flag outdated sections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)
