+# Lokal
+
+Lokal is a local business aggregation site helping you to shop locally by
+providing a one-stop-shop for your local community. Set your profile and start
+shopping today!
+
+# Features
+
+- User Registration/Sign in via `phx_gen_auth`
+- `Dockerfile` and example `docker-compose.yml`
+- Automatic migrations in `MIX_ENV=prod` or Docker image
+- JS linting with [standard.js](https://standardjs.com), HEEx linting with
+  [heex_formatter](https://github.com/feliperenan/heex_formatter)
+
+# Installation
+
+1. Clone the repo
+2. Run `mix setup`
+3. Run `mix phx.server` to start the development server
+
+# Configuration
+
+For development, I recommend setting environment variables with
+[direnv](https://direnv.net).
+
+## `MIX_ENV=dev`
+
+In `dev` mode, Lokal will listen for these environment variables on compile.
+
+- `HOST`: External url to generate links with. Set these especially if you're
+  behind a reverse proxy. Defaults to `localhost`.
+- `PORT`: External port for urls. Defaults to `443`.
+- `DATABASE_URL`: Controls the database url to connect to. Defaults to
+  `ecto://postgres:postgres@localhost/lokal_dev`.
+
+## `MIX_ENV=prod`
+
+In `prod` mode (or in the Docker container), Lokal will listen for these environment variables at runtime.
+
+- `HOST`: External url to generate links with. Set these especially if you're
+  behind a reverse proxy. Defaults to `localhost`.
+- `PORT`: Internal port to bind to. Defaults to `4000` and attempts to bind to
+  `0.0.0.0`. Must be reverse proxied!
+- `DATABASE_URL`: Controls the database url to connect to. Defaults to
+  `ecto://postgres:postgres@lokal-db/lokal`.
+- `ECTO_IPV6`: Controls if Ecto should use ipv6 to connect to PostgreSQL.
+  Defaults to `false`.
+- `POOL_SIZE`: Controls the pool size to use with PostgreSQL. Defaults to `10`.
+- `SECRET_KEY_BASE`: Secret key base used to sign cookies. Must be generated
+  with `mix phx.gen.secret` and set for server to start.
