-## Building
-
-- To build the project, run `cargo build`; to run all the tests, run `cargo test`.
-- One external dependency `protoc` is needed, please install it before build and make sure both executable and protobuf definition accessible

-## Dev Container / Github Codespaces
-The easiest way to start contributing is via Dev Container. This container works both locally in Visual Studio Code as well as [Github Codespaces](https://github.com/features/codespaces). To open the project in vscode you will need the [Dev Containers extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers). For codespaces you will need to [create a new codespace](https://github.com/apache/datafusion).
-
-With the extension installed you can run the following from the `Command Palette` to get started
-```
-> Dev Containers: Clone Repository in Container Volume...
-```
-
-In the subsequent popup paste the url to the repo and hit enter.
-```
-https://github.com/apache/datafusion
-```
-
-This will create an isolated Workspace in vscode, including all tools and environment variables required to build, test and run.
