 next track is picked automatically. It is meant for personal use (a couple of
 simultaneous listeners), not for public broadcasting.
 
-## How it works
+## Features
 
-radieo is built as two layers, each running in its own Docker container and
-sharing a cache volume:
+- **Always-on stream**: MP3 at 192 kbps over HTTP, several simultaneous
+  listeners.
+- **Automatic programming from mixable sources**, drawn at weighted random:
+  - a playlist from any [OpenSubsonic](https://opensubsonic.netlify.app/)-compatible
+    server ([Navidrome](https://www.navidrome.org/), Gonic, Airsonic…);
+  - a hand-maintained list of [yt-dlp](https://github.com/yt-dlp/yt-dlp) URLs
+    (Bandcamp, SoundCloud, YouTube…); playlist/album/label/artist URLs are
+    expanded and one track is picked at random each round;
+  - a [ListenBrainz](https://listenbrainz.org/) recommendations feed, whose
+    suggestions are resolved to a real file (Subsonic first, then yt-dlp).
+- **Cross-source de-duplication**: each track is canonicalized to a MusicBrainz
+  recording MBID (no API key), so the same song from two sources collapses to
+  one; a recent-plays window prevents repeats.
+- **Push-with-cache**: tracks are downloaded *ahead* of playback into a local
+  cache with LRU retention; if the pipeline ever runs dry the stream falls back
+  to the tracks already aired, and stays silent at a cold start rather than
+  looping.
+- **Jingles**: station jingles inserted every two songs, plus time-of-day
+  jingles (noon, snack time, ...) played once when their time comes.
+- **Smooth playback**: a 3 s crossfade between tracks.
+- **Built-in web player** at `http://localhost:8000/`: now playing (linked to
+  its source page), track history, skip button, per-track download, volume
+  memory, live auto-reconnect, prefetch progress, and a synthwave look.
+- **Robust in a container**: Docker healthcheck, graceful shutdown, retries on
+  transient HTTP errors.
 
-- **`ingest`** (Python) — the brain. It decides what to play next, resolves and
-  downloads tracks into a local cache, keeps a pre-filled queue, and exposes the
-  next track over HTTP at `GET /next`. *(currently it only serves the cache
-  directory; the download providers come in later milestones — see roadmap)*
-- **`stream`** (Liquidsoap) — deliberately dumb. It pulls the next track from
-  the `ingest` daemon, broadcasts the audio over HTTP, and falls back to the
-  already-aired tracks (via `/fallback.m3u`) if the daemon has nothing ready.
-
-Playback sources (planned): a [Navidrome](https://www.navidrome.org/) library
-via the OpenSubsonic API, arbitrary tracks fetched with
-[yt-dlp](https://github.com/yt-dlp/yt-dlp) (Bandcamp, SoundCloud, YouTube…), and
-listening suggestions from a ListenBrainz RSS feed.
-
-## Usage
+## Getting started
 
 Requirements: Docker with Compose v2.
 
-```sh
-# Drop some .mp3 files into the cache directory
-cp /path/to/music/*.mp3 cache/
+### 1. Jingles (optional)
 
-# Build and start the stream
-docker compose up -d
+Drop `.mp3` files into `jingles/`: they rotate in every two songs. For
+time-of-day jingles, add files to these subfolders (each played once per day
+just after its slot):
 
-# Listen (VLC, a browser, any audio player)
-#   http://localhost:8000/radio.mp3
-```
+| Folder            | Plays around |
+| ----------------- | ------------ |
+| `jingles/midi/`   | 11:00        |
+| `jingles/moment/` | 15:00, 21:00 |
+| `jingles/gouter/` | 16:30        |
 
-Stop it with `docker compose down`.
+An empty folder simply means no jingle, the music plays through.
 
-The stream is MP3 at 192 kbps. Multiple clients can listen at the same time.
-New files dropped into `cache/` are picked up automatically (the playlist is
-reloaded when the directory changes).
-
-## Configuration
-
-Copy `.env.example` to `.env` and fill in your Navidrome details:
+### 2. Configure the sources (`.env`)
 
 ```sh
 cp .env.example .env
-# edit .env: RADIEO_NAVIDROME_URL / USER / PASSWORD / PLAYLIST
 ```
 
-If the Navidrome variables are left empty, the source is simply disabled and
-the stream plays whatever is already in `cache/` (the milestone-1/2 behaviour).
+Fill in `.env`:
 
-For the yt-dlp source, list the URLs to draw from in `config/urls.txt` (copy
-`config/urls.txt.example`). Each line is either a direct track URL or a
-container URL (playlist, album, label, artist page) from which one track is
-picked at random.
+- **OpenSubsonic server**: `RADIEO_SUBSONIC_URL` / `USER` / `PASSWORD` and the
+  playlist to broadcast in `RADIEO_SUBSONIC_PLAYLIST` (name or id). Works with
+  any OpenSubsonic-compatible server (Navidrome, Gonic, Airsonic…). Leave empty
+  to disable this source.
+- **Mix**: `RADIEO_WEIGHT_SUBSONIC` / `RADIEO_WEIGHT_YTDLP` /
+  `RADIEO_WEIGHT_LISTENBRAINZ` set the relative draw weight of each source
+  (`0` disables one).
+- Optional: `RADIEO_RETENTION_KEEP` (cached tracks kept on disk),
+  `RADIEO_CANONICAL_ENABLED`, `RADIEO_USER_AGENT`.
 
-For the ListenBrainz source, set `RADIEO_LISTENBRAINZ_URL` to your
-recommendations feed (the Atom syndication URL, e.g.
-`https://listenbrainz.org/syndication-feed/user/<you>/recommendations/weekly-exploration`,
-or a local file path under `config/` for testing). ListenBrainz only *names*
-tracks, so each suggestion is resolved to a real file: Navidrome first
-(a `search3` lookup), then yt-dlp (`ytsearch1:`) as a fallback. The
-MusicBrainz recording MBID that the feed already carries is used as the
-track's canonical identity (no extra lookup needed).
+### 3. yt-dlp URL list (`config/urls.txt`)
 
-The relative mix between sources is set by `RADIEO_WEIGHT_NAVIDROME` /
-`RADIEO_WEIGHT_YTDLP` / `RADIEO_WEIGHT_LISTENBRAINZ` (a weight of 0 disables a
-source); an empty URL / missing file also disables the corresponding source.
+```sh
+cp config/urls.txt.example config/urls.txt
+```
 
-Open the player at `http://localhost:8000/` — a small web page with an
-`<audio>` player and the current track (title/artist), which it refreshes from
-`GET /nowplaying`. The raw stream stays at `http://localhost:8000/radio.mp3`.
+Add one URL per line: a single track, or a playlist/album/label/artist page to
+pick from. The file is mounted read-only, so you can edit it without rebuilding.
+A missing file just disables the yt-dlp source.
 
-## Current status
+### 4. ListenBrainz suggestions
 
-**Milestone 7 — polish: done.**
+Point `RADIEO_LISTENBRAINZ_URL` (in `.env`) at your recommendations syndication
+feed, e.g.:
 
-- A small web player is served by Liquidsoap at `http://localhost:8000/`
-  (alongside the stream), showing the track currently on air; it reads
-  `/nowplaying` (JSON), fed from the broadcast source's live metadata — so it
-  is accurate even though the ingest daemon runs a track ahead (prefetch).
-- A 3 s crossfade smooths transitions between tracks.
-- The fallback only replays tracks **already aired**: the ingest daemon exposes
-  them as an `/fallback.m3u` playlist (served into a local file the stream
-  watches). The pre-fetch buffer (downloaded but not-yet-played tracks) is
-  excluded, so at cold start the list is empty and the stream stays **silent**
-  rather than looping the two or three tracks being pre-fetched. Once the buffer
-  drains mid-stream, it degrades gracefully across every track heard so far
-  instead of a tight loop.
-- Robustness: the ingest daemon shuts down cleanly on SIGTERM (fast
-  `docker compose down`), has a Docker healthcheck on `/healthz` (the stream
-  waits for it to be healthy), and outgoing HTTP calls retry transient
-  connection errors.
+```
+RADIEO_LISTENBRAINZ_URL=https://listenbrainz.org/syndication-feed/user/<you>/recommendations/weekly-exploration
+```
 
-**Playback (milestones 3–6).**
+ListenBrainz only *names* tracks; each suggestion is resolved to a concrete file
+(an OpenSubsonic `search3`, then a yt-dlp `ytsearch1:` fallback) and keyed by the
+MusicBrainz MBID the feed already carries. Leave the variable empty to disable.
+A local file path under `config/` also works for testing.
 
-- Three playback sources feed a weighted scheduler: a Navidrome/OpenSubsonic
-  playlist, a hand-maintained list of yt-dlp URLs (`config/urls.txt`), and a
-  ListenBrainz recommendations feed. Container URLs (playlist/album/label/artist)
-  are expanded and one track is drawn at random.
-- ListenBrainz suggestions carry a MusicBrainz recording MBID, a title and an
-  artist; each is resolved to a concrete file (Navidrome `search3` first, then
-  a yt-dlp `ytsearch1:` fallback) and keyed directly by its MBID — so the same
-  song is de-duplicated across all three sources for free.
-- Each track is canonicalized to a MusicBrainz recording MBID (no API key
-  needed; ~1 req/s, best-effort, results cached in SQLite). This gives a
-  source-agnostic identity, so the same song from two sources collapses to one;
-  when no confident match is found it falls back to a normalized
-  `(artist, title)` key. The scheduler uses this canonical key for anti-repeat,
-  with the providers applying a cheap locator filter first.
-- Each source has its own fetcher (Subsonic stream / yt-dlp download); files are
-  cached ahead of playback (prefetch buffer) and decoded by Liquidsoap.
-- Play history and LRU retention are tracked in a SQLite database under
-  `state/`: only the N most recently played files are kept on disk
-  (`RADIEO_RETENTION_KEEP`, default 20). Orphaned download temp files are swept
-  on startup.
-- `GET /next` returns the next track as an annotated Liquidsoap URI with real
-  title/artist metadata (or an empty body when nothing is ready).
-- `stream` (Liquidsoap v2.4.5) pulls via `request.dynamic` and falls back to the
-  local `cache/` directory; `mksafe` guarantees silence rather than a crash.
-- HTTP stream served at `http://localhost:8000/radio.mp3` (MP3, 192 kbps),
-  multiple simultaneous listeners supported.
+### 5. Run it
 
-The radio is feature-complete for personal use. A future nicety would be moving
-the source weights and settings from environment variables into a single config
-file.
+```sh
+docker compose up -d
+```
 
-## Roadmap
+Open the player at **`http://localhost:8000/`**; the raw stream is at
+`http://localhost:8000/radio.mp3` (open it in VLC or any audio player). Stop with
+`docker compose down`.
 
-1. ✅ **Broadcasting skeleton** — Liquidsoap serving the cache directory.
-2. ✅ **Ingestion daemon** — Python daemon exposing `GET /next`; Liquidsoap
-   switches to a `request.dynamic` source with the cache as fallback.
-3. ✅ **Navidrome provider** — play from an OpenSubsonic playlist, with caching,
-   LRU retention and play history.
-4. ✅ **yt-dlp provider** — fetch tracks from a maintained URL/artist list;
-   weighted mixing between sources.
-5. ✅ **Canonicalizer** — MusicBrainz MBID lookup for source-agnostic
-   de-duplication.
-6. ✅ **ListenBrainz provider** — parse the recommendations feed and resolve
-   each suggestion to Navidrome or yt-dlp.
-7. ✅ **Polish** — crossfade, web player, quieter logs, robustness (graceful
-   shutdown, healthcheck, HTTP retries). *(Config file: still env-based.)*
+The station name shown in the player is the `STATION_NAME` constant near the top
+of `stream/index.html`.
+
+## Architecture
+
+radieo is two Docker containers sharing a cache volume. `ingest` is the brain;
+`stream` is a deliberately dumb broadcaster.
+
+```
+Providers                Scheduler              Fetchers            Broadcast
+─────────                ─────────              ────────            ─────────
+Subsonic ──┐                                 ┌ Subsonic ┐
+yt-dlp ────┼─▶ weighted pick ─▶ Canonicalizer┤          ├▶ cache ─▶ queue ─▶ Liquidsoap ─▶ HTTP
+ListenBrz ─┘   + anti-repeat    (MBID)       └ yt-dlp ──┘  (LRU)   /next     (request.dynamic
+                (SQLite)                                                      + jingles + fallback)
+```
+
+**`ingest`** (Python) chooses what to play, resolves and downloads it ahead of
+time, and serves it over an internal HTTP API:
+
+- *Providers* produce a resolved reference (which backend + a locator);
+  *fetchers* turn that into a local file (`Subsonic` stream / `yt-dlp` download).
+- The *scheduler* draws a source by weight, applies anti-repeat, and runs the
+  *canonicalizer* (MusicBrainz MBID, cached, rate-limited, best-effort) for a
+  source-agnostic identity.
+- A *prefetch queue* keeps a few ready tracks; a SQLite database under `state/`
+  holds play history, the MBID cache, and LRU cache-file retention.
+- API: `GET /next` (annotated Liquidsoap URI), `/fallback.m3u` (already-aired
+  tracks), `/status` (prefetch progress), `/healthz`.
+
+**`stream`** (Liquidsoap) pulls `/next` via `request.dynamic`, inserts jingles
+(a `switch` that also handles the time-of-day slots), applies the crossfade and
+`mksafe`, and outputs the MP3. On the same harbor port 8000 it also serves the
+web player and its API: `/nowplaying`, `/history`, `/skip`, `/download`, plus
+`/ingest/status`.
+
+Only port **8000** is published to the host. The browser never talks to `ingest`
+directly — the Liquidsoap harbor acts as a small reverse proxy for the data the
+player needs (e.g. `/ingest/status`), keeping everything on a single origin.
