 This package contains the code to use [Vonage's Voice API](https://developer.vonage.com/en/voice/voice-api/overview) in Python. This package includes methods for working with the Voice API. It also contains an NCCO (Call Control Object) builder to help you to control call flow.
 
+## Structure
+
+There is a `Voice` class which contains the methods used to call Vonage APIs. To call many of the APIs, you need to pass a Pydantic model with the required options. These can be accessed from the `vonage_voice.models` subpackage. Errors can be accessed from the `vonage_voice.errors` module.
+
+## Usage
+
+It is recommended to use this as part of the main `vonage` package. The examples below assume you've created an instance of the `vonage.Vonage` class called `vonage_client`, like so:
+
+```python
+from vonage import Vonage, Auth
+
+vonage_client = Vonage(Auth('MY_AUTH_INFO'))
+```
+
+### Create a Call
+
+To create a call, you must pass an instance of the `CreateCallRequest` model to the `create_call` method. If supplying an NCCO, import the NCCO actions you want to use and pass them in as a list to the `ncco` model field.
+
+```python
+from vonage_voice.models import CreateCallRequest, Talk
+
+ncco = [Talk(text='Hello world', loop=3, language='en-GB')]
+
+call = CreateCallRequest(
+    to=[{'type': 'phone', 'number': '1234567890'}],
+    ncco=ncco,
+    random_from_number=True,
+)
+
+response = vonage_client.voice.create_call(call)
+print(response.model_dump())
+```
+
+### List Calls
+
+```python
+# Gets the first 100 results and the record_index of the
+# next page if there's more than 100
+calls, next_record_index = vonage_client.voice.list_calls()
+
+# Specify filtering options
+from vonage_voice.models import ListCallsFilter
+
+call_filter = ListCallsFilter(
+    status='completed',
+    date_start='2024-03-14T07:45:14Z',
+    date_end='2024-04-19T08:45:14Z',
+    page_size=10,
+    record_index=0,
+    order='asc',
+    conversation_uuid='CON-2be039b2-d0a4-4274-afc8-d7b241c7c044',
+)
+
+calls, next_record_index = vonage_client.voice.list_calls(call_filter)
+```
+
+### Get Information About a Specific Call
+
+```python
+call = vonage_client.voice.get_call('CALL_ID')
+```
+
+### Transfer a Call to a New NCCO
+
+```python
+ncco = [Talk(text='Hello world')]
+vonage_client.voice.transfer_call_ncco('UUID', ncco)
+```
+
+### Transfer a Call to a New Answer URL
+
+```python
+vonage_client.voice.transfer_call_answer_url('UUID', 'ANSWER_URL')
+```
+
+### Hang Up a Call
+
+End the call for a specified UUID, removing them from it.
+
+```python
+vonage_client.voice.hangup('UUID')
+```
+
+### Mute/Unmute a Participant
+
+```python
+vonage_client.voice.mute('UUID')
+vonage_client.voice.unmute('UUID')
+```
+
+### Earmuff/Unearmuff a UUID
+
+Prevent/allow a specified UUID participant to be able to hear audio.
+
+```python
+vonage_client.voice.earmuff('UUID')
+vonage_client.voice.unearmuff('UUID')
+```
+
+### Play Audio Into a Call
+
+```python
+from vonage_voice.models import AudioStreamOptions
+
+# Only the `stream_url` option is required
+options = AudioStreamOptions(
+    stream_url=['https://example.com/audio'], loop=2, level=0.5
+)
+response = vonage_client.voice.play_audio_into_call('UUID', options)
+```
+
+### Stop Playing Audio Into a Call
+
+```python
+vonage_client.voice.stop_audio_stream('UUID')
+```
+
+### Play TTS Into a Call
+
+```python
+from vonage_voice.models import TtsStreamOptions
+
+# Only the `text` field is required
+options = TtsStreamOptions(
+    text='Hello world', language='en-ZA', style=1, premium=False, loop=2, level=0.5
+)
+response = voice.play_tts_into_call('UUID', options)
+```
+
+### Stop Playing TTS Into a Call
+
+```python
+vonage_client.voice.stop_tts('UUID')
+```
+
+### Play DTMF Tones Into a Call
+
+```python
+response = voice.play_dtmf_into_call('UUID', '1234*#')
+```
