+# Discord Command Bot
+
+This function allows you to implement a simple command-interaction for a Discord bot using Discord Interactions. This bot is able to verify requests and handle them. In its current implementation, it responds to the '/hello' command with a message.
+
+## Environment Variables
+
+To ensure the function operates as intended, ensure the following variable is set:
+
+- **DISCORD_PUBLIC_KEY**: This is the public key of your Discord bot.
+
+## Discord Setup
+
+Before you can use this function, you need to have a bot set up on the Discord Developer Portal. You can create a new bot on the [Discord Developer Portal](https://discord.com/developers/applications) and navigate to the Bot section under the settings page of your application. Here, you can click the 'Add Bot' button.
+
+## Discord API & Interactions
+
+This function utilizes the Discord Interactions API. Interactions are the foundation upon which commands, components, and future user-input features are built. Discord provides a range of interaction types like `APPLICATION_COMMAND` which we use for our '/hello' command.
+
+To add an interaction to your bot, you need to define it first in the Discord Developer Portal under your application settings. Go to the 'Interactions' section and add a new command. In this case, you would add a command named 'hello'. 
+
+## Usage
+
+This function supports the interaction of command type coming from Discord:
+
+1. **Executing the '/hello' command**
+
+   - **Interaction Type:** APPLICATION_COMMAND
+   - **Command:** '/hello'
+   - **Response:** 
+     - On success, the function will respond with "Hello from Appwrite 👋".
+     - If the command is not '/hello', the function will respond with a simple acknowledgement (PONG).
+
+## Error Handling
+
+In case of any error during interaction handling, the function will return a 500 error with the message "Failed to process interaction".

+# 🤖 Discord Command Bot Function
 
-This function allows you to implement a simple command-interaction for a Discord bot using Discord Interactions. This bot is able to verify requests and handle them. In its current implementation, it responds to the '/hello' command with a message.

-## Discord Setup
+**Parameters**
 
-Before you can use this function, you need to have a bot set up on the Discord Developer Portal. You can create a new bot on the [Discord Developer Portal](https://discord.com/developers/applications) and navigate to the Bot section under the settings page of your application.

+| Name                  | Description                      | Location | Type   | Sample Value    |
+| --------------------- | -------------------------------- | -------- | ------ | --------------- |
+| x-signature-ed25519   | Signature of the request payload | Header   | string | `d1efb...aec35` |
+| x-signature-timestamp | Timestamp of the request payload | Header   | string | `1629837700`    |
 
-## Discord API & Interactions
+**Response**
 
-This function utilizes the Discord Interactions API. Interactions are the foundation upon which commands, components, and future user-input features are built. Discord provides a range of interaction types like `APPLICATION_COMMAND` which we use for our '/hello' command.
+Sample `200` Response:
 
-To add an interaction to your bot, you need to define it first in the Discord Developer Portal under your application settings. Go to the 'Interactions' section and add a new command. In this case, you would add a command named 'hello'. 
+Returns a Discord message object.
 
-## Usage
+```json
+{
+  "type": 4,
+  "data": {
+    "content": "Hello from Appwrite 👋"
+  }
+}
+```

+}
+```
