 Data flow graphs use registry endpoints to pull WebAssembly (WASM) modules and graph definitions from container registries. You can configure the endpoint settings, authentication, and other settings to connect to Azure Container Registry (ACR) or other OCI-compatible registries.

 - Use Azure Container Registry (ACR) to store WASM modules and graphs.
 - Install the OCI Registry As Storage (ORAS) CLI to push WASM modules to the registry.
 - Develop custom WASM modules by following guidance in [Develop WebAssembly modules for data flow graphs](howto-develop-wasm-modules.md).
