+## Development Environment
+
+Below are instructions for setting up your development environment.
+
+### Prerequisites
 
 This project is written in Rust. You will need to install Rust and Cargo to build this project. You can find instructions for installing Rust [here](https://www.rust-lang.org/tools/install).
 
 Also, this project maintains Node.js integrations. You will need to install Node.js and npm to build the Node.js integrations. You can find instructions for installing Node.js [here](https://nodejs.org/en/download/).
 
-## Build and Test
+### Build and Test
 
 Usual commands like `cargo build`, `cargo test` or `cargo watch` (you need [cargo-watch](https://crates.io/crates/cargo-watch) for this) should work.
 
-### Snapshot testing
+#### Snapshot testing
 
 When you want to update snapshot tests, [cargo-insta](https://crates.io/crates/cargo-insta) is required. Instead of `cargo test`, run `cargo insta test` for snapshot-testing-aware results. When snapshots are to be added or updated, run `cargo insta review` to review and apply the changes.
 
-### Coverage
+#### Coverage
 
 To generate coverage file, run `make coverage`. This will generate a `coverage/lcov.info` file which can be loaded by the [Coverage Gutters](https://marketplace.visualstudio.com/items?itemName=ryanluker.vscode-coverage-gutters) extension.
