+# Development & Contributing
+
+Be sure to read the [Code of Conduct](https://github.com/axelrindle/github-version-checker/blob/main/CODE_OF_CONDUCT.md)
+
+## Setup
+
+First of all clone the git repository :)
+
+```shell
+$ git clone https://github.com/axelrindle/github-version-checker.git
+```
+
+and then install the dependencies
+
+```shell
+$ npm ci
+```
+
+By running [`npm ci`](https://docs.npmjs.com/cli/v9/commands/npm-ci) instead of [`npm i`](https://docs.npmjs.com/cli/v9/commands/npm-install) it is ensured that the dependency tree is installed exactly as stated in the [`package-lock.json`](https://docs.npmjs.com/cli/v9/configuring-npm/package-lock-json) file. That guarantees the usage of identical dependency trees throughout development.
+
+## Working on the packages
+
+1. Bootstrap the Lerna environment
+
+```shell
+$ npx lerna bootstrap
+```
+
+2. Do your changes on a seperate branch, e.g. `feature/my-bug-fix`
+
+## Contributing to the documentation
+
+All documentation resided within the `docs/` directory. Is is built upon [Docusaurus](https://docusaurus.io/) and primarily written in Markdown.
+
+Install dependencies using
+
+```shell
+$ npm ci
+```
+
+and start the development server by running
+
+```shell
+$ npm start
+```
+
+To produce a production build, run
+
+```shell
+$ npm run build
+```
+
+That produces a static site which can be served using
+
+```shell
+$ npm run serve
+```
