Set title on unacceptable merch type error

Shops now have a "type" and keywords of items they only deal with.

Also add vendors table in preparation for implementing the endpoint.

 # BazaarRealmAPI
+
 The API for the Bazaar Realm Skyrim mod which is responsible for storing and
 serving data related to the mod to all users.
 
 Right now, the types of data the API stores and the endpoints to access them
 are (all prefixed under `/v1`, the API version):
 
-* `/owners`: Every player character that has registered with this API server.
-   Contains their unique api key. Owners own shops.
-* `/shops`: Metadata about each shop including name, description, and who owns
-   it.
-* `/interior_ref_lists`: Lists of in-game ObjectReferences that are in the
-   interior of individual shops. When a user visits a shop, these references
-   are loaded into the cell.
-* `/merchandise_lists`: Lists of in-game Forms that are in the merchant chest
-   of individual shops. When a user visits a shop, these forms are loaded
-   onto the shop's shelves and are purchasable.

+resources, which should be suitable for a group of friends to share shops
+with each other.
 
 It uses the [`warp`](https://crates.io/crates/warp) web server framework and
 [`sqlx`](https://crates.io/crates/sqlx) for database queries to a [PostgreSQL
 database](https://www.postgresql.org).
 
+The API was designed with performance as a high priority. When it serves a
+response, it also caches that response so future queries for the same data
+can be returned in less than 1ms. To reduce data sent over the network,
+clients can use the
+[ETag](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/ETag)
+headers to indicate to the server what version of the data they have cached
+so the server can send a 304 response with no data if the resource hasn't
+changed since the client last requested. Using the
+[Accept](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Accept)
+header, clients can also opt for the more space-efficient and faster to
+deserialize [bincode](https://github.com/servo/bincode) format instead of the
+JSON default.

-## Development Setup
+## Docker Setup
+
+The easiest way to get the server up and running is using Docker.
+
+1. Download and install [Docker Desktop](https://www.docker.com/get-started)
+2. In PowerShell, cmd.exe, or a terminal run `docker pull postgres:alpine` then `docker pull thallada/bazaarrealm:latest`
+3. Run (replacing `<password>` with a secure generated password):
+
+```
+docker run -d --name postgres --network=bazaarrealm --network-alias=db --env POSTGRES_DB=bazaarrealm --env POSTGRES_USER=bazaarrealm --env POSTGRES_PASSWORD=<password> postgres:alpine
+```
+
+4. Run (replacing `<password>` with what you generated in previous step):
+
+```
+docker run -d --name bazaarrealm -p 3030:3030 --network=bazaarrealm --network-alias=api --env DATABASE_URL=postgresql://bazaarrealm:<password>@db/bazaarrealm --env HOST=http://localhost:3030 thallada/bazaarrealm:latest
+```
+
+5. The server should now be available at `http://localhost:3030`.
+
+## Docker-Compose Setup
+
+An alternative way to set up the API, is to use `docker-compose` which can
+orchestrate setting up the database and web server containers for you. This
+method is more useful if you would like to make changes to the API code and
+test them out.
+
+1. Download and install [Docker Desktop](https://www.docker.com/get-started)
+2. Git clone this repo into a folder of your choosing: `git clone https://github.com/thallada/BazaarRealmAPI.git`
+3. Create a new file `.env.docker` in the checked out `bazaar_realm_api`
+   folder with the contents (replacing `<password>` with a secure generated
+   password):
+
+```
+DATABASE_URL="postgresql://bazaarrealm:<password>@db/bazaarrealm"
+RUST_LOG="bazaar_realm_api=debug,warp=info"
+HOST="http://localhost:3030"
+PORT=3030
+POSTGRES_DB=bazaarrealm
+POSTGRES_USER=bazaarrealm
+POSTGRES_PASSWORD=<password>
+```
+
+3. In the checked out repo, run: `docker-compose build`
+4. Once that completes, run: `docker-compose up`
+
+## Manual Development Setup
+

+the following steps to get everything setup.

-4. Create a new file at `src/db/refinery.toml` with the contents:
+
+4. Install
+   [`sqlx_cli`](https://github.com/launchbadge/sqlx/tree/master/sqlx-cli) with
+   `cargo install --version=0.1.0-beta.1 sqlx-cli --no-default-features --features postgres`
+5. Run `sqlx migrate --source db/migrations run` which will run all the database 
+   migrations.
+6. Run `./devserver.sh` to run the dev server (by default it listens at
+   `127.0.0.1:3030`). Note that this runs the server in debug mode and shouldn't
+   be used to serve requests from the mod. You can build the release version of
+   the server with `cargo build --release`.
+
+## TLS setup
+
+If you would like to access the server over HTTPS, you can use [Let's
+Encrypt](https://letsencrypt.org/) to generate a SSL certificate and key and
+provide it to the API. Once you use [certbot](https://certbot.eff.org/) to
+generate the certificate and key for your domain in
+`/etc/letsencrypt/live/<domain>/`, run the api server with:
+
 ```
-[main]
-db_type = "Postgres"
-db_host = "localhost"
-db_port = "5432"
-db_user = "bazaarrealm"
-db_pass = "<database-password-here>"
-db_name = "bazaarrealm"
+docker run -d --name bazaarrealm --network=host --env DATABASE_URL=postgresql://bazaarrealm:<password>@localhost/bazaarrealm --env PORT=443 --HOST=https://<domain> --env TLS_CERT=/etc/letsencrypt/live/<domain>/fullchain.pem --env TLS_KEY=/etc/letsencrypt/live/<domain>/privkey.pem -v /etc/letsencrypt/:/etc/letsencrypt/ thallada/bazaarrealm:latest
 ```
-5. Run `cargo run -- -m` which will compile the app in debug mode and run the 
-   database migrations.
-6. Run `./devserver.sh` to run the dev server (by default it listens at 
-   `127.0.0.1:3030`).
+
+This command assumes that you are on Linux and you have a running postgres
+database already set up outside of docker. See Manual Development Setup for
+database setup instructions.
+
+The server should be accessible at your domain: `https://<domain>`.

+## Database Migrations
+
+Migrations are handled by `sqlx`. When the server initially starts, it will
+connect to the database and check if there are any migrations in
+`db/migrations` that have not yet been applied. It will apply any at that
+time and then continue starting the server.
+
+A new migration can be created by running: `sqlx migrate add <name>`.
+
+To allow the docker container for the API to get built in CI without a
+database, the `sqlx-data.json` file needs to be re-generated every time the
+database schema changes or any query is updated. It can be generated with `cargo 
+sqlx prepare`.
