 ## Manifest Files
 
-* **default.xml** - External releasable components. Used for release builds.
+This repository contains several manifest files:
+* **tdx-base.xml** - Minimal confidential computing image configuration (uses [tdx-base_yocto_build_config.env](env_files/tdx-base_yocto_build_config.env))
+* **tdx-bob.xml** - Searcher node image configuration (uses [bob_yocto_build_config.env](env_files/bob_yocto_build_config.env))
+* **tdx-rbuilder.xml** - Builder/validator node image configuration (uses [rbuilder_yocto_build_config.env](env_files/rbuilder_yocto_build_config.env))
+
+## Build Profiles
+
+This repository supports multiple build profiles, each tailored for specific use cases and defined by its corresponding manifest file:
+
+* **tdx-base**: Minimal confidential computing image. 
+  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.
