+# BigBiggerBiggestBot
+
+A Telegram bot for logging gym workouts, with an embedded Mini App.
+
+Send workouts as plain text, forward them from Saved Messages, or tap
+through a structured log form inside Telegram. History, stats, notes,
+edit & delete, JSON/CSV export — all per-user, all in SQLite.
+
+## Format
+
+Send messages like:
+
+```
+Bench press: 4x8x35
+Shoulder press (3032): 8x25, 5x35, 6x40
+Pull-ups: 3x10
+```
+
+- `SETSxREPSxWEIGHT` — uniform sets
+- `REPSxWEIGHT, REPSxWEIGHT, ...` — per-set (weight/reps vary)
+- Omit weight for bodyweight exercises
+- `(machine_id)` is optional (gym equipment ID)
+- Blank line separates superset groups; consecutive lines form a superset
+- Both `,` and `.` work as decimal separators
+
+## Commands
+
+- `/start` — help & open Mini App
+- `/history` — recent workouts
+- `/stats` — summary (total workouts, sets, volume)
+- `/delete <id>` — soft-delete a workout
+- `/export` — download all data as JSON
+- `/feedback <text>` — send feedback to the bot author
+
+## Run locally
+
+```bash
+nix run
+```
+
+This launches:
+- API server (port 8080)
+- cloudflared tunnel for the Mini App
+- Telegram bot (polling)
+
+Put your bot token (from [@BotFather](https://t.me/BotFather)) in
+`~/.secrets/bigbiggerbiggestbot` or a `.env` file:
+
+```
+BOT_TOKEN=123456:your-bot-token-here
+```
+
+`nix develop` drops you into a dev shell with Python + deps.
+
+## Tests
+
+```bash
+nix develop --command pytest tests/ -v
+```
+
+## Deployment
+
+Runs as a systemd service. A timer pulls this repo periodically and
+restarts the service when the remote has new commits — push to `main`
+and the bot redeploys itself within ~15 minutes.
+
+The SQLite database lives next to the code at `workouts.db` (gitignored).
+
+## Architecture
+
+- `bot.py` — Telegram command handlers, polling, message parsing
+- `server.py` — aiohttp REST API + static file server for the Mini App
+- `db.py` — SQLite data layer (workouts, supersets, exercises, feedback; soft delete)
+- `parser.py` — workout text → structured data
+- `webapp/` — Mini App (HTML/CSS/vanilla JS, Telegram WebApp SDK)
+- `start.py` — orchestrator: starts server + tunnel + bot, wires up the Mini App URL
+- `tests/` — pytest suite for parser + db
