To begin, sign up for a GNews API key if you haven't already. The API key is essential for authenticating your requests to the GNews API and fetching news data. Visit the GNews website, create an account, and follow the instructions to generate your API key.

Set up your development environment by installing necessary programming languages and tools. For this guide, we'll use Python, a popular choice for working with APIs and databases. Ensure you have Python installed, along with necessary libraries like `requests` for making HTTP requests.

Write a Python script to send a GET request to the GNews API endpoint. Use the API key to authenticate your request. Specify query parameters such as keywords, language, or country to tailor the news articles you wish to retrieve. Parse the JSON response to extract relevant article data.

Example:
```python
import requests

api_key = 'YOUR_GNEWS_API_KEY'
url = f'https://gnews.io/api/v4/top-headlines?token={api_key}&lang=en'

response = requests.get(url)
articles = response.json().get('articles', [])
```

Install Redis on your local machine or server. Follow the instructions specific to your operating system. Once installed, start the Redis server. You can verify it's running by using the `redis-cli` to connect and issue basic commands like `PING`.

Use the `redis-py` library to connect your Python script to the Redis server. First, install the library using pip (`pip install redis`). Then, create a connection to your Redis server within your script.

Example:
```python
import redis

redis_client = redis.StrictRedis(host='localhost', port=6379, decode_responses=True)
```

Iterate over the news articles fetched from the GNews API. For each article, store its data in Redis. Choose a suitable data structure, like a Redis hash, to store attributes such as title, description, and URL, using a unique key for each article.

Example:
```python
for article in articles:
article_id = article['source']['id'] or article['title']
redis_client.hmset(f"article:{article_id}", article)
```

After storing data, verify that the articles are correctly saved in Redis. Use the `redis-cli` to list keys and fetch article data. This step ensures that your data transfer process is functioning as expected.

Example:
```
redis-cli
> KEYS article:*
> HGETALL article:example_id
```

By following these steps, you can effectively move data from GNews to Redis without relying on third-party connectors or integrations. Adjust the code snippets to fit your specific use case and requirements.
