+The Media Sucker
+================
+
+This program watches your CD/DVD drive.
+When you put a CD or DVD in, 
+it will suck the content off,
+eject the drive,
+and then re-encode the content to a compressed format.
+
+## What It Supports
+
+At the time I'm writing this README, it will:
+
+* Rip audio CDs, look them up in cddb, encode them to VBR MP3, then tag them.
+* Rip video DVDs, transcode them to mkv
+
+## How To Run This
+
+First you have to build it.
+It will build on a raspberry pi.
+
+    docker build --tag=media-sucker .
+
+You'll need a place to store all your precious media:
+
+    incoming=/path/to/incoming
+    mkdir -P $incoming
+    chown 911:911 $incoming
+
+Then you can run it:
+
+    docker run -d --restart=unless-stopped \
+      --name=sucker \
+      --device cdrom --device dvd --device sr0 \
+      -v $incoming:/incoming \
+      media-sucker
+
+Or you can put it in a `docker-compose.yaml` file:
+
+```yaml
+services:
+  sucker:
+    image: media-sucker
+    volumes:
+      - type: bind
+        source: /path/to/incoming
+        target: /incoming
+```
+
+Stick a video DVD or audio CD in,
+and the drive should spin up for a while,
+then spit your media back out.
+Then, eventually, you'll have a new `.mkv` file (for video)
+or a new directory of `.mp3` files (for audio).
+
+You can watch what it's doing:
+
+    docker logs --since=1m -f sucker
+
+## A note on filenames and tags
+
+This program does the absolute minimum to try and tag your media properly.
+
+For DVDs, that means reading the "title" stored on the DVD,
+which I've seen vary from very helpful (eg. "Barbie A Fashion Fairytale")
+to ridiculously unhelpful (eg. "FBWTF2").
+But at least it's usually unique for each DVD and at least somewhat
+related to the DVD contents.
+
+For CDs, the situation is even worse.
+Audio CDs do not store any metadata,
+so CDDB takes the length of every track in seconds and tries to match that
+against something a user has uploaded in the past.
+This is wrong a whole lot of the time.
+
+If CDDB can't find a match for an audio CD,
+this program will append the datestamp of the rip to the album name,
+in the hopes that you can remember about what time you put each CD in the drive.
+So for stuff like multi-CD audiobooks, that's pretty helpful.
+
+But the end result in almost every case is that you're going to have to
+manually edit the metadata.
+
+## Why I Wrote This
+
+The `automatic-ripping-machine` looks really badass.
+I spent about two days trying to get a Docker container built for it,
+and another day trying to get it to actually read my drive.
+I got it reading the drive exactly once, and then never again.
+
+That's when I gave up and created my own thing,
+which is pretty janky,
+but works a lot better for me,
+in that it actually does something.
+
+### Why You Should Run This
+
+The only reason I can think of that anybody would want to use this is if they,
+like me,
+are too dumb to get the `automatic-ripping-machine` to work.
