+# Contributing to Frame Control
+
+This guide exists to save both sides time. The process is borrowed from
+[pi](https://github.com/badlogic/pi-mono/blob/main/CONTRIBUTING.md).
+
+## Just want to report something?
+
+Use the [feedback form](https://frame-control.pages.dev/feedback/). It needs no
+GitHub account, and what you send becomes an issue here that stays open.
+
+## The One Rule
+
+**You must understand your code.** If you can't explain what your change does
+and how it interacts with the rest of the app, your PR will be closed.
+
+Using AI to write code is fine. Submitting AI-generated slop you don't
+understand is not.
+
+## Contribution gate
+
+Issues and PRs opened on GitHub by new contributors are auto-closed by default.
+A maintainer reviews auto-closed issues regularly and reopens worthwhile ones.
+Issues that don't meet the quality bar below won't be reopened or get a reply.
+
+Approval happens through maintainer replies on issues:
+
+- `lgtmi`: your future issues won't be auto-closed
+- `lgtm`: your future issues and PRs won't be auto-closed
+
+The word must be at the start of the reply (optionally after one or more

+
+## Quality bar for issues
+
+Use one of the issue templates, and keep it short, concrete and worth reading.
+
+- If it doesn't fit on one screen, it's too long.
+- Write in your own voice. If you must use an LLM, say so in a clearly labelled

+- State the bug or request clearly, and why it matters.
+- For bugs, include your OS, your SteamOS build (Steam Settings → System), and

+## Before opening a PR
+
+Don't open a PR until a maintainer has approved you with `lgtm`. Open an

+Then check your change:
+
+```sh
+python3 -m unittest discover -s tests   # server tests; no headset needed
+node --test site/test/*.test.mjs        # website feedback function
+```

+## Blocking
+
+If you ignore this document twice, or spam the tracker with agent-generated

+
+## Why auto-close?
+
+This is a hobby project with one maintainer. Auto-closing is a buffer against

-the Plasma desktop doesn't need to be open. It uses its own profile
-(`~/.config/chromium-xr`) and DevTools on loopback port 9223, so it doesn't

-**From the Steam library (verified 2026-09-26).** `steam` adds a non-Steam
-shortcut called "Chromium XR" (with the Flathub Chromium icon, if that's
-installed) through the Steam client's DevTools port, the same way as T3 Code
-([apks.md](apks.md)), without restarting Steam. It saves the app id in
-`~/Applications/ChromiumXR/shortcut-appid`, so rerunning it, even after you
-rename the shortcut in the library, doesn't add a second one. On this Frame
-the shortcut app id is 2240749789. Launching it from the library gives
-Chromium its own panel, `valve.steam.desktopgame.2240749789`, like any other
-app. A Steam launch doesn't open a DevTools port, so `check` needs `launch`.
-Chromium runs one browser per profile: while the Steam-launched one is open,
-`launch` opens its URL in that window, without DevTools, then prints
-`failed: ... exited` because no new window appeared. Close it first.
-
-**Seccomp is off.** The wrapper passes `--disable-seccomp-filter-sandbox`. With
-the XR seccomp policy on, SteamVR's client reads `/proc/self/status` through
-Chrome's file broker and gets the broker's pid. SteamVR then binds the app to
-the wrong process ("Unable to init path manager: VRInitError_Init_Internal")

+# Website
+
+The Frame Control website, <https://frame-control.pages.dev>, on Cloudflare Pages.
+
+- `public/`: static pages. `/` is the landing page, `/feedback/` the feedback form, `/privacy/` the privacy note.
+- `functions/api/feedback.js`: `POST /api/feedback`, which turns the form into a GitHub issue labelled `feedback`.
+- `lib/feedback.js`: validation and issue formatting, tested by `test/feedback.test.mjs`.
+- `public/js/site.js`: settings, including the Ko-fi page name for the donate buttons.
+
+## Feedback → GitHub issues
+
+The function needs a `GITHUB_TOKEN` secret: a fine-grained token with **Issues: read and write** on
+`saphid/frame-control` only. Issues are opened as the token's owner, so they pass the contributor gate
+(`.github/workflows/issue-gate.yml`) and stay open. Without the token the form answers 503 and offers a
+prefilled GitHub issue instead.
+
+```sh
+cd site
+npx wrangler pages secret put GITHUB_TOKEN --project-name frame-control
+```
+
+Spam protection: a hidden honeypot field, a 3-second minimum fill time, 5 submissions per hour per IP
+(a salted hash, kept in the `FEEDBACK_RL` KV namespace for about an hour), and 100 a day in total.
+User text has `@mentions` and `#123` references broken so nobody gets pinged.
+
+## Run and deploy
+
+```sh
+cd site
+node --test test/*.test.mjs
+npx wrangler pages dev --port 8788           # local; put GITHUB_TOKEN/GITHUB_REPO in .dev.vars to test issues
+npx wrangler pages deploy --branch main      # production
+```
+
+Point `GITHUB_REPO` in `.dev.vars` at a scratch repo when testing locally so test issues don't land on the real tracker.
