-## Message Components
-So, you want to use Message components? Well you're in luck! Below is a quick overview of how to use them

+private async Task MyMessageComponentHandler(SocketInteraction arg)
+{
+    // Parse the arg

+    
+    // Respond with the update message response type. This edits the original message if you have set AlwaysAcknowledgeInteractions to false.
+    // You can also use "ephemeral" so that only the original user of the interaction sees the message
+    await parsedArg.RespondAsync($"Clicked {parsedArg.Data.CustomId}!", type: InteractionResponseType.UpdateMessage, ephemeral: true);
+    
+    // You can also followup with a second message
+    await parsedArg.FollowupAsync($"Clicked {parsedArg.Data.CustomId}!", type: InteractionResponseType.ChannelMessageWithSource, ephemeral: true);
+}
+```
+
+### Sending messages with buttons
 Theres a new field in all `SendMessageAsync` functions that takes in a `MessageComponent`, you can use it like so:
 ```cs
-var builder = new ComponentBuilder().WithButton("Hello!", ButtonStyle.Primary, customId: "id_1");
+var builder = new ComponentBuilder().WithButton("Hello!", customId: "id_1", ButtonStyle.Primary, row: 0);
 await Context.Channel.SendMessageAsync("Test buttons!", component: builder.Build());
 ```
 
+### Sending messages with selection dropdowns
+Theres a new field in all `SendMessageAsync` functions that takes in a `MessageComponent`, you can use it like so:
+```cs
+var builder = new ComponentBuilder()
+  .WithSelectMenu(new SelectMenuBuilder()
+  .WithCustomId("id_2")
+  .WithLabel("Select menu!")
+  .WithPlaceholder("This is a placeholder")
+  .WithOptions(new List<SelectMenuOptionBuilder>()
+  {
+    new SelectMenuOptionBuilder()
+      .WithLabel("Option A")
+      .WithEmote(Emote.Parse("<:evanpog:810017136814194698>"))
+      .WithDescription("Evan pog champ")
+      .WithValue("value1"),
+    new SelectMenuOptionBuilder()
+      .WithLabel("Option B")
+      .WithDescription("Option B is poggers")
+      .WithValue("value2")
+  }));
+await Context.Channel.SendMessageAsync("Test selection!", component: builder.Build());
+```
+
+> Note: You can only have 5 buttons per row and 5 rows per message. If a row contains a selection dropdown it cannot contain any buttons.
