 ## Overview
 
-DataFusion Distributed is a distributed execution framework that enables DataFusion DataFrame and SQL queries to run in a distributed fashion. This project provides the infrastructure to scale DataFusion workloads across multiple nodes in a cluster.
+Distributed DataFusion is a distributed execution framework that enables DataFusion DataFrame and SQL queries to run in a distributed fashion. This project provides the infrastructure to scale DataFusion workloads across multiple nodes in a cluster.
 
 This is an open source version of the distributed DataFusion prototype, extracted from DataDog's internal implementation and made available to the community.

+**Clean Rebuild**: If you need to completely clean and rebuild (removes all build artifacts):
+
+```bash
+# Clean rebuild in debug mode
+./clean_and_build.sh
+
+# Clean rebuild in release mode (optimized)
+./clean_and_build.sh --release
+```

 #### Using Cargo Directly
 
-To build the project in debug mode:
+You can also build the project directly with Cargo (the build.rs script will automatically handle Protocol Buffer compilation):
 
 ```bash
+# Build in debug mode
 cargo build
 ```
 
-To build the project in release mode (optimized):
+```bash
+# Build in release mode (optimized)  
+cargo build --release
+```
+
+**Clean Build Artifacts**: To clean previous build artifacts before rebuilding:
 
 ```bash
+# Clean all build artifacts (removes target/ directory contents)
+cargo clean
+
+# Then rebuild
 cargo build --release
 ```
 
+**Note**: Both commands, `build.sh` script and `cargo` automatically invoke `build.rs`, which handles Protocol Buffer compilation before building the main crate. The main advantage of using `./build.sh` is the user-friendly output and usage examples it provides.

 To make your cluster aware of specific table schemas, you’ll need to define a new environment variable, DFRAY_TABLES, when starting each worker and proxy. This variable should specify tables whose data is stored in Parquet files.For example, the following setup registers two tables—customer and nation—along with their corresponding data sources.
 
 ```bash
