 ## Getting Started
 
 ### Prerequisites
+
 To compile GreptimeDB from source, you'll need the following:
 - Rust
 - Protobuf
 - OpenSSL
 
 #### Rust
+
 The easiest way to install Rust is to use [`rustup`](https://rustup.rs/), which will check our `rust-toolchain` file and install correct Rust version for you.
 
 #### Protobuf
+
 `protoc` is required for compiling `.proto` files. `protobuf` is available from
 major package manager on macos and linux distributions. You can find an
 installation instructions [here](https://grpc.io/docs/protoc-installation/).
