+# vv_ext — красивая оболочка для vv.micialware.ru
+# Стек: Flask + SQLite + чистый JS + Tailwind CDN. Без сборки, без авторизации.
+
+## Структура
+# app.py — бэкенд: 5 ручек API + SQLite
+# scanner.py — сканирует папку с видео, добавляет новые файлы в БД
+# frontend/index.html, app.js, style.css — лента + сетка
+# deploy/vv.conf — nginx, deploy/vv.service — systemd
+
+## Быстрый старт (локально)
+# python -m venv .venv && source .venv/bin/activate
+# pip install -e .
+# VIDEO_DIR=/path/to/videos python scanner.py   # наполнить БД
+# VIDEO_DIR=/path/to/videos python app.py        # http://127.0.0.1:8000
+
+## API
+# GET  /api/health
+# GET  /api/tags -> [{name, count}]
+# GET  /api/videos?tag=&q=&sort=new|likes&page=1&per_page=30 -> {items, page, pages, total}
+# POST /api/videos/<file>/like -> {likes} (1 лайк с IP в сутки)
+# POST /api/videos/<file>/tags {"tag": "..."} -> {tags}
+# POST /api/scan -> пересканировать VIDEO_DIR
+
+## Прод (на VPS где уже лежит nginx-раздача)
+# 1. залить frontend/ в /var/www/vv_ext/
+# 2. app.py + db.sqlite в /opt/vv_ext/, VIDEO_DIR=/var/www/vv/ (где .mp4/.webm)
+# 3. deploy/vv.conf -> /etc/nginx/conf.d/, deploy/vv.service -> /etc/systemd/system/
+# 4. systemctl enable --now vv && systemctl reload nginx
