 ## Finding contributions to work on
 Looking at the existing issues is a great way to find something to contribute on. As our projects, by default, use the default GitHub issue labels (enhancement/bug/duplicate/help wanted/invalid/question/wontfix), looking at any 'help wanted' issues is a great place to start.

+# Developer Guide
+
+This document describes how to set up your development environment to build and test the Babushka Node wrapper.
+
+### Development Overview
+
+The Babushka Node wrapper consists of both TypeScript and Rust code. Rust bindings for Node.js are implemented using [napi-rs](https://github.com/napi-rs/napi-rs). The Node and Rust components communicate using the [protobuf](https://github.com/protocolbuffers/protobuf) protocol.
+
+
+### Build
+
+- Follow the building instructions for the Node wrapper in the [Build from source](https://github.com/aws/babushka/blob/main/node/README.md#build-from-source) section to clone the code and build the wrapper.
+- For a fast build, execute `npm run build`. This will perform a full,  unoptimized build, which is suitable for developing tests. Keep in mind that performance is significantly affected in an unoptimized build, so it's required to build with the `build:release` or `build:benchmark` option when measuring performance.
+- If your modifications are limited to the TypeScript code, run `npm run build-external` to build the external package without rebuilding the internal package.
+- If your modifications are limited to the Rust code, execute `npm run build-internal` to build the internal package and generate TypeScript code.
+- To generate Node's protobuf files, execute `npm run build-protobuf`. Keep in mind that protobuf files are generated as part of full builds (e.g., `build`, `build:release`, etc.).
+
+> Note: Once building completed, you'll find the compiled JavaScript code in the `node/build-ts` folder.
+
+
+### Test
+
+To run tests, use the following command:
+
+```bash
+npm test
+```
+
+### Submodules
+
+After pulling new changes, ensure that you update the submodules by running the following command:
+
+```bash
+git submodule update
+```
+
+### Linters
+Development on the Node wrapper may involve changes in either the TypeScript or Rust code. Each language has distinct linter tests that must be passed before committing changes.
+
+#### Language-specific Linters
+
+__TypeScript:__
+- ESLint
+- Prettier
+
+__Rust:__
+- clippy
+- fmt
+
+#### Running the linters
+1. TypeScript
+    ```bash
+    # Run from the `node` folder
+    npm install eslint-plugin-import@latest  @typescript-eslint/parser @typescript-eslint/eslint-plugin eslint-plugin-tsdoc eslint typescript eslint-plugin-import@latest eslint-config-prettier
+    npm i
+    npx eslint . --max-warnings=0
+    ```
+2. Rust
+    ```bash
+    # Run from the `node/rust-client` folder
+    rustup component add clippy rustfmt
+    cargo clippy --all-features --all-targets -- -D warnings
+    cargo fmt --manifest-path ./Cargo.toml --all
+    ```
+
+### Recommended extensions for VS Code
+- [Prettier - Code formatter](https://marketplace.visualstudio.com/items?itemName=esbenp.prettier-vscode) - JavaScript / TypeScript formatter.
+- [ESLint](https://marketplace.visualstudio.com/items?itemName=dbaeumer.vscode-eslint) - linter.
+- [Jest Runner](https://marketplace.visualstudio.com/items?itemName=firsttris.vscode-jest-runner) - in-editor test runner.
+- [Jest Test Explorer](https://marketplace.visualstudio.com/items?itemName=kavod-io.vscode-jest-test-adapter) - adapter to the VSCode testing UI.
+-   [rust-analyzer](https://marketplace.visualstudio.com/items?itemName=rust-lang.rust-analyzer) - Rust language support for VSCode.
