+## About
+
+A matrix bot that tracks shopping lists.
+
+
+Add the bot to your Matrix room, and start telling it your shopping list.
+
+Then add stores, and assign your items to one or moreany stores where you would shop for that item.
+
+Matrix shop bot can then list back your shopping list for any given store.
+
+This bot works well with, and is included in [Cadbury, the many purpose Matrix bot](https://codeberg.org/EdTheDev/matrix-cadbury).
+
+## Privacy
+
+This bot exists because most modern shopping tools have no respect for our privacy.
+
+All data is stored locally in a sqlite database on the host where you run the bot.
+
+Shop bot contains no trackers of any kind.
+
+## Usage
+
+Configure the necessary environment variables, and run with `make serve`.
+
+Invite the bot to a Matrix channel, and it will accept automatically, if it can.
+
+Use `!shop help`, to get started.
+
+> Tip: Additional setup is required to add a Matrix bot to an encrypted channel.

+
+## TODO List
+
+- [ ] add PurchaseRecord table to track how often an item is purchased at a given store
+- [ ] add a `quick.list` command that populates a store shopping list with the most commonly shopped items at that store from the PurchaseRecord table in the database
