···
 ## Build
 
 ### From Source
+
 First configure .env.example and save it to .env
 
 If DATABASE_URL is set, it will connect to a Postgres DB. If blank, it will use an sqlite db in /data
···
 ```bash
 #set api-domain to where you will be deploying the link shortener, eg: link.example.com, default is localhost:8080
 git clone https://github.com/waveringana/simplelink && cd simplelink
-./build.sh api-domain=localhost:8080
+./build.sh
 cargo run
 ```
 
 On an empty database, an admin-setup-token.txt is created as well as pasted into the terminal output. This is needed to make the admin account.
 
 Alternatively if you want a binary form
+
 ```bash
 ./build.sh --binary
 ```
+
 then check /target/release for the binary named `SimpleGit`
 
 ### From Docker
+
 ```bash
-docker build --build-arg API_URL=http://localhost:8080 -t simplelink .
+docker build --build-arg -t simplelink .
 docker run -p 8080:8080 \
     -e JWT_SECRET=change-me-in-production \
     -v simplelink_data:/data \
···
 ```
 
 ### From Docker Compose
+
 Adjust the included docker-compose.yml to your liking; it includes a postgres config as well.
