+## Requirements
+
+To run your Crawlee code on Apify platform, you need an Apify account. If you don't have one yet, you can sign up [here](https://console.apify.com/sign-up).
+
+Additionally, you must have the [Apify CLI](https://docs.apify.com/cli/) installed on your computer. For installation instructions, refer to the [Installation guide](https://docs.apify.com/cli/docs/installation).
+
+Finally, ensure that the [Apify SDK] (https://docs.apify.com/sdk/python/) is installed in your project. You can install it using `pip`:
+
+```bash
+pip install apify
+```

 ## Logging into Apify platform from Crawlee
 
 To access your [Apify account](https://console.apify.com/sign-up) from Crawlee, you must provide credentials - your [API token](https://console.apify.com/account?tab=integrations). You can do that either by utilizing [Apify CLI](https://docs.apify.com/cli/) or with environment variables.
