 # Twigs Server
 
-This is the backend application that powers the [Android](https://github.com/wbrawner/twigs-android), [iOS](https://github.com/wbrawner/twigs-ios), and [web](https://github.com/wbrawner/twigs-web) applications for Twigs, a personal finance/budgeting app. 
+This is the backend application that powers the [Android](https://git.wbrawner.com/twigs-android), [iOS](https://git.wbrawner.com/twigs-ios), and [web](https://git.wbrawner.com/twigs-web) applications for Twigs, a personal finance/budgeting app. None of these apps are complete, so expect bugs, and they are all in various stages of development, so expect some feature disparity between platforms.
 
 ## Prerequisites
 
 - JDK 14 or newer
-- MySQL 5.7 or newer
+- PostgreSQL 13 or newer
 - (optional) Docker
 
 ## Running
 
-Prior to running the app, make sure you have a MySQL server running, with a database and user ready to go. To avoid the hassle of figuring out how to get it installed locally, using Docker is recommended, and a sample `docker-compose.yml` file is included in the root of the repository. If you already have a MySQL server running, you can run the app from the command line with gradle:

To avoid the hassle of figuring out how to get it installed locally, using Docker is recommended, and a sample `docker-compose.yml` file is included in the root of the repository. If you already have a PostgreSQL server running, you can run the app from the command line with gradle:
 
-    ./gradlew bootRun
+    ./gradlew run
 
-By default, twigs will try to connect to the `budget` database on `localhost`, using `budget` as the user and password. To change these values, you can modify the `api/src/main/resources/application.properties` file (but don't commit it!), or better yet, set the appropriate environment variables using the uppercase names and replacing the `.`s with `_`s. For example, to change the `spring.datasource.username` property (the database username), you could set the value in an environment variable called `SPRING_DATASOURCE_USERNAME`.
+## Configuration
+
+Some parameters of Twigs can be configured via environment variables:
+
+Environment Variable|Default Value|Note
+:---:|:---:|:---
+`TWIGS_PORT`|`8080`|Port for web server to listen on
+`TWIGS_DB_HOST`|`localhost`|PostgreSQL server host
+`TWIGS_DB_PORT`|`5432`|PostgreSQL server port
+`TWIGS_DB_NAME`|`twigs`|PostgreSQL database name
+`TWIGS_DB_USER`|`twigs`|PostgreSQL database user
+`TWIGS_DB_PASS`|`twigs`|PostgreSQL database password
+`TWIGS_PW_SALT`||Salt to use for password, generated if empty or null
 
 ## Building
 
 Building the app is also handled with gradle:
 
-    ./gradlew bootJar
+    ./gradlew shadowJar
