 ## Installation

 Please note that this package is separate from the legacy `serpapi` module, which is available on PyPi as `google-search-results`. This package is maintained by SerpApi, and is the recommended way to access the SerpApi service from Python.
 
-## Usage
+## Simple Usage
 
 Let's start by searching for Coffee on Google:
 
-```pycon
->>> import serpapi
->>> s = serpapi.search(q="Coffee", engine="google", location="Austin, Texas", hl="en", gl="us")
-```
-
-The `s` variable now contains a `SerpResults` object, which acts just like a standard dictionary, with some convenient functions added on top.
+```python
+import os
+import serpapi
 
-Let's print the first result:
+client = serpapi.Client(api_key=os.getenv("SERPAPI_KEY"))
+results = client.search({
+  "engine": "google",
+  "q": "coffee"
+})
 
-```pycon
->>> s["organic_results"][0]["link"]
-'https://en.wikipedia.org/wiki/Coffee'
+print(results)
 ```
 
-Let's print the title of the first result, but in a more Pythonic way:
+The `results` variable now contains a `SerpResults` object, which acts just like a standard dictionary, with some convenient functions added on top.
 
-```pycon
->>> s["organic_results"][0].get("title")
-'Coffee - Wikipedia'
-```
+This example runs a search for "coffee" on Google. It then returns the results as a regular Python Hash.
+ See the [playground](https://serpapi.com/playground) to generate your own code.
+
+The SerpApi key can be obtained from [serpapi.com/signup](https://serpapi.com/users/sign_up?plan=free).
 
-The [SerpApi.com API Documentation](https://serpapi.com/search-engine-apis) contains a list of all the possible parameters that can be passed to the API.
+Environment variables are a secure, safe, and easy way to manage secrets.
+ Set `export SERPAPI_KEY=<secret_serpapi_key>` in your shell.
+ Python accesses these variables from `os.environ["SERPAPI_KEY"]`.
