+# Polls in Discord.Net
+
+Polls are... Polls! 
+
+![example poll](images/poll.png)
+
+This guide will explain how to use polls in your applications.
+
+> [!NOTE]
+> To get contents of polls sent by users other than your bot you need to enable `GatewayIntent.MessageContent` intent.
+
+## Creating polls
+
+A poll is part of a message; to send one you need to pass a [PollProperties] object into the `poll` parameter of any method that can be used to send messages. (ex. `SendMessageAsync`, `RespondAsync`, etc)
+
+[!code-csharp[Creating polls](samples/create-poll.cs)]
+
+> [!WARNING]
+> Due to limitations of the Discord API it's not possible to send attachments in a messages with a poll.
+
+> [!NOTE]
+> It is not possible to modify polls after them being created.
+
+
+## Managing polls
+
+### Ending polls
+You can expire polls early by calling `EndPollAsync` on an [IUserMessage] with a poll.
+
+[!code-csharp[Ending polls](samples/end-poll.cs)]
+
+### Getting poll answer voters
+To get voters for a specific answer call `GetPollAnswerVotersAsync(answerId)` on an [IUserMessage] with a poll.
+
+[!code-csharp[Getting poll answer voters](samples/get-poll-voters.cs)]
+
+### Retrieving poll results
+You can get results of a poll by simply getting an [IUserMessage] and checking the `IUserMessage.Poll.Results` property. Alteratively you can check the results on a `MessageUpdated` gateway event.
+
+
+## Gateway events
+
+### Poll votes
+You can receive information about poll votes live using following events:
+- `PollVoteAdded`
+- `PollVoteRemoved`
+
+> [!NOTE]
+> These events are only sent if the client has `GatewayIntents.GuildMessagePolls` or `GatewayIntents.DirectMessagePolls` intents enabled. It will receive events for polls in guild or dm channels respectively.
+
+### Poll expiry
+On poll expiry the `MessageUpdated` event is fired.
