+Test Provider
+*************
 
+If you're just learning the ropes or doing some quick prototyping, you can use a test
+provider, `eth-tester <https://github.com/ethereum/eth-tester>`_. This provider includes
+some accounts prepopulated with test ether and automines each transaction into a block.
+Web3.py makes this test provider available via ``EthereumTesterProvider``:

+The hardware requirements are `steep <https://ethereum.org/en/developers/docs/nodes-and-clients/run-a-node/#top>`_,

+Remote Providers
+****************
 
 The quickest way to interact with the Ethereum blockchain is to use a remote node provider,
-like `Infura <https://infura.io/>`_. You can connect to a remote node by specifying the
-endpoint, just like the previous local node example:
+like `Infura <https://infura.io/>`_, `Alchemy <https://www.alchemy.com/>`_, or `QuickNode <https://www.quicknode.com/>`_.
+You can connect to a remote node by specifying the endpoint, just like the previous local node example:
 
 .. code-block:: python
 
    >>> from web3 import Web3
-   >>> w3 = Web3(Web3.HTTPProvider('https://mainnet.infura.io/v3/<infura-project-id>'))
-
-This endpoint is provided by Infura after you create a (free) account.
-
-Again, a convenience method exists to save a few keystrokes:
-
-.. code-block:: python
-
-    >>> from web3.auto.infura import w3
-    >>> w3.eth.block_number
-    4000000
 
-Note that this requires your Infura Project ID to be set as the environment variable
-``WEB3_INFURA_PROJECT_ID`` before running your script or application:
+   >>> w3 = Web3(Web3.HTTPProvider('https://<your-provider-url>'))
 
-.. code-block:: shell
+   >>> w3 = Web3(Web3.WebsocketProvider('wss://<your-provider-url>'))
 
-    $ export WEB3_INFURA_PROJECT_ID=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
+This endpoint is provided by the remote node service after you create an account.
