+## Build Profiles
+
+This repository supports multiple build profiles, each tailored for specific use cases:
+
+* **tdx-base**: Minimal confidential computing image with TPM2 and UEFI Secure Boot support. 
+  See [tdx-base/README.md](config_files/tdx-base/README.md) for details.
+
+* **tdx-bob**: Specialized image for running searcher nodes with podman support and searcher-specific configurations. 
+  See [tdx-bob/README.md](config_files/tdx-bob/README.md) for details.
+
+* **tdx-rbuilder**: Comprehensive environment for running Ethereum validators and builders, including reth and lighthouse clients. 
+  See [tdx-rbuilder/README.md](config_files/tdx-rbuilder/README.md) for details.
+
+Each profile's configuration and setup scripts are maintained in the `config_files/` directory. See the profile-specific READMEs for detailed information about features, requirements, and build configurations.
