Updating Docs

Documentation lives in three places: the root README.md, docs/commands/ (auto-generated), and VHS tape recordings (GIF demos).

Root README

README.md follows a fixed structure:

1. •Title + badge + one-line description
2. •Motivation paragraph
3. •Hero GIF (demo.gif)
4. •Quickstart (install, init, state, render)
5. •State file reference
6. •How it works (directory layout)
7. •Requirements
8. •Development
9. •Support + License

When adding a new command or changing behavior, update the relevant sections. Keep the quickstart concise — detailed docs belong in docs/commands/.

Command Reference Docs

Auto-generated from cobra command definitions. Never edit docs/commands/*.md by hand.

Regenerate with:

make gendocs

This runs cmd/gendocs/main.go, which:

1. •Calls cobra/doc.GenMarkdownTree to produce one .md per command
2. •Injects GIF demos where a matching tapes/<name>.gif exists

VHS Tape Recordings

VHS tapes produce GIF demos from terminal recordings. There are two types:

Hero Demo (demo.tape)

Full walkthrough shown in the root README. Regenerate with:

make demo

Per-Command Tapes (docs/commands/tapes/*.tape)

One tape per command, embedded in generated docs. Regenerate all with:

make vhs

Tape Template

All tapes share these standard settings:

Output <output-path>.gif

Set Shell "bash"
Set FontFamily "Menlo"
Set FontSize 16
Set Width 700          # 900 for hero demo
Set Height 300         # 500 for hero demo
Set Padding 20
Set Theme "Catppuccin Mocha"
Set TypingSpeed 60ms
Set PlaybackSpeed 1
Set LetterSpacing 0
Set LineHeight 1.2

Hidden Setup Block

Every tape starts with a hidden block that configures the environment:

Hide

Type `export FLOW_HOME=/tmp/flow-demo/.flow`
Enter
Sleep 200ms

Type `export PATH="$(pwd):$PATH"`
Enter
Sleep 200ms

Type "clear"
Enter
Sleep 500ms

Show

This assumes demo-setup.sh has already run (the Makefile handles this). The script creates a temp git repo at /tmp/demo/app with a feature/ipv6 branch.

Key VHS Commands

• •Type "text" — types text at TypingSpeed
• •Type@0ms "text" — instant typing (for vim commands)
• •Enter — press enter
• •Sleep 500ms — pause
• •Hide / Show — toggle recording visibility
• •Escape — press escape key

Adding a New Command Tape

1. •Create docs/commands/tapes/<command>.tape
2. •Use the template above with Width 700, Height 300
3. •Output to docs/commands/tapes/<command>.gif
4. •Add the vhs call to the Makefile vhs target
5. •Run make docs to regenerate everything

Make Commands

Full Docs Rebuild

After any change to commands, flags, or demos:

make docs

This regenerates all markdown docs and re-records all per-command GIFs.
