 ## ARM and Bicep
 
-Each catalog item has _main.bicep_ file in addition to the ARM template (_azuredeploy.json_). This is because the ARM templates in this repository are written in [bicep](https://github.com/Azure/bicep) and transpiled to ARM using the [build-arm.py](/tools/build-arm.py) script in the [tools](/tools/) folder.  The script simply walks the Environments folder and runs the [`az bicep build`](https://learn.microsoft.com/en-us/cli/azure/bicep?view=azure-cli-latest#az-bicep-build) command on each folder's main.bicep file.
