+## CI/CD & Multi-Platform Builds
+
+This project includes a Dagger pipeline for building binaries for multiple platforms:
+- macOS ARM64 (darwin/arm64)
+- macOS AMD64 (darwin/amd64)
+- Windows AMD64 (windows/amd64)
+- Linux AMD64 (linux/amd64)
+
+The pipeline is defined in [`ci/dagger.go`](./ci/dagger.go). It outputs binaries named `valhallir-deconvolver-<os>-<arch>` in the `dist/` directory.
+
+### Usage
+
+1. Install the Dagger Go SDK:
+   ```sh
+   go install dagger.io/dagger@latest
+   go mod tidy
+   ```
+2. Run the pipeline:
+   ```sh
+   go run ci/dagger.go
+   ```
+
+### Troubleshooting Dagger
+- If you see `could not import dagger.io/dagger`, make sure you have installed the Dagger Go SDK and run `go mod tidy`.
+- The pipeline requires Docker or a compatible container runtime.
+
 ## Troubleshooting
 
 ### Common Issues
 
-**"File is not a valid WAV file" error**
-- Check that files are uncompressed WAV format
-- Avoid MP3, FLAC, or other compressed formats
+**Input file errors**
+- Input files must be uncompressed WAV format. MP3, FLAC, or other compressed formats are not supported.
+- Input sample rate, bit depth, and channel count are automatically converted (no need to preprocess).
 
 **"Invalid sample rate" error (output)**
 - Use only supported output sample rates: 44100, 48000, 88200, 96000

 ### Performance
 - Processing time depends on file length
 - FFT-based deconvolution is much faster than time-domain methods
