+## Crawlee Project Prerequisites
+
+To contribute to the Crawlee project, you'll need some prerequisites to ensure the project is set up properly. These are the required dependencies for development:
+
+- [Node.js](https://nodejs.org/en) v22.17.0
+
+- [Yarn](https://yarnpkg.com/) v4.8.1 
+
+
+## Crawlee Installation and Building
+
+### Installing Yarn
+This project uses Yarn v4 to manage dependencies. The easiest way to install it is using [corepack](https://nodejs.org/api/corepack.html) (distributed with Node.js >= 16.10):
+
+```shell
+corepack enable
+```
+
+Once enabled, corepack will automatically use the correct Yarn version specified in the project's `packageManager` field.
+
+Alternatively, if you use [Volta](https://volta.sh/) for Node.js version management, it will automatically use the correct Node.js and Yarn versions specified in the project's `package.json`.
+
+### Building the Project
+After enabling corepack, you will need to be in the project root directory and install the dependencies before building:
+
+```shell
+yarn install
+```
+
+After installing the dependencies, you can build the Crawlee project.
+
+```shell
+yarn build
+```
+
