 ## Compile
 
-```
-sh ./scripts/compile
-```
+Binaries for different platforms can be built using `docker buildx` and specifying a --platform directive. Tested platforms are `linux/amd64` and `linux/arm64`.
 
-## Run Server
+```bash
+docker buildx create --name captions-builder --use
+docker buildx inspect --bootstrap
+docker buildx build --platform linux/amd64 -t captions .
+docker run --platform=linux/amd64 -v .:/app/out captions
 
-```
-./main
+./captions
 ```
 
-## Trigger Job
-
-Use PostMan to send a request to `http://localhost:8080` send a raw body that looks something like this
+## Run command
 
+```bash
+./captions \
+  --input input.mp4 \
+  --segments segments.json \
+  --output output.mp4 \
+  --font "Montserrat ExtraBold 56" \
+  --highlighter true \
