+## REST API Client
+Import the RESTClient.
+```python
+from polygon import RESTClient
+```
+Create a new client with your [API key](https://polygon.io/dashboard/api-keys)
+```python
+client = RESTClient(api_key="<API_KEY>")
+```
+### Using the Client
+Request data using client methods.
+```python
+ticker = "AAPL"
+
+# List Aggregates (Bars)
+bars = client.get_aggs(ticker=ticker, multiplier=1, timespan="day", from_="2023-01-09", to="2023-01-10")
+for bar in bars:
+    print(bar)
+
+# Get Last Trade
+trade = client.get_last_trade(ticker=ticker)
+print(trade)
+
+# List Trades
+trades = client.list_trades(ticker=ticker, timestamp="2022-01-04")
+for trade in trades:
+    print(trade)
+
+# Get Last Quote
+quote = client.get_last_quote(ticker=ticker)
+print(quote)
+
+# List Quotes
+quotes = client.list_quotes(ticker=ticker, timestamp="2022-01-04")
+for quote in quotes:
+    print(quote)
+```
+Note: For parameter argument examples check out our docs. All required arguments are annotated with red asterisks " * " and argument examples are set.
+Check out an example for Aggregates(client.get_aggs) [here](https://polygon.io/docs/stocks/get_v2_aggs_ticker__stocksticker__range__multiplier___timespan___from___to)
+
+## Launchpad
+Users of the Launchpad product will need to pass in certain headers in order to make API requests using the RequestOptionBuilder.
 Example can be found [here](./examples/launchpad).
 
+Import classes
+```python
+from polygon import RESTClient
+from polygon.rest.models.request import RequestOptionBuilder
+```
+### Using the client
+Create client and set options
+```python
+# create client
+c = RESTClient(api_key="API_KEY")
+
+# create request options
+options = RequestOptionBuilder().edge_headers(
+    edge_id="YOUR_EDGE_ID",  # required
+    edge_ip_address="IP_ADDRESS",  # required
+)
+```
+Request data using client methods.
+```python
+# get response
+res = c.get_aggs("AAPL", 1, "day", "2022-04-04", "2022-04-04", options=options)
+
+# do something with response
+```
+Checkout Launchpad readme for more details on RequestOptionBuilder [here](./examples/launchpad)
+
+## WebSocket Client 
+
+Import classes
+```python
+from polygon import WebSocketClient
+from polygon.websocket.models import WebSocketMessage
+from typing import List
+```
+### Using the client
+Create a new client with your [API key](https://polygon.io/dashboard/api-keys) and subscription options.
+```python
+# Note: Multiple subscriptions can be added to the array 
+# For example, if you want to subscribe to AAPL and META,
+# you can do so by adding "T.META" to the subscriptions array. ["T.AAPL", "T.META"]
+# If you want to subscribe to all tickers, place an asterisk in place of the symbol. ["T.*"]
+ws = WebSocketClient(api_key=<API_KEY>, subscriptions=["T.AAPL"])
+```
+Create a handler function and run the WebSocket.
+```python
+def handle_msg(msg: List[WebSocketMessage]):
+    for m in msg:
+        print(m)
+
+ws.run(handle_msg=handle_msg)
+```
+Check out more detailed examples [here](https://github.com/polygon-io/client-python/tree/master/examples/websocket).
