+# 🗑 Wipe Appwrite Bucket
+
+A Deno cloud function to wipe a complete bucket in Appwrite by passing the bucket id as a payload.
+
+_Example input:_
+
+```json
+{
+  "bucketId":"profilePictures"
+}
+```
+
+_Example output:_
+
+```json
+{
+  "success":true
+}
+```
+
+## 📝 Environment Variables
+
+List of environment variables used by this cloud function:
+
+- **APPWRITE_FUNCTION_ENDPOINT** - Endpoint of Appwrite project
+- **APPWRITE_FUNCTION_API_KEY** - Appwrite API Key
+- **APPWRITE_FUNCTION_PROJECT_ID** - Appwrite project ID. If running on Appwrite, this variable is provided automatically.
+
+## 🚀 Deployment
+
+There are two ways of deploying the Appwrite function, both having the same results, but each using a different process. We highly recommend using CLI deployment to achieve the best experience.
+
+### Using CLI
+
+Make sure you have [Appwrite CLI](https://appwrite.io/docs/command-line#installation) installed, and you have successfully logged into your Appwrite server. To make sure Appwrite CLI is ready, you can use the command `appwrite client --debug` and it should respond with green text `✓ Success`.
+
+Make sure you are in the same folder as your `appwrite.json` file and run `appwrite deploy function` to deploy your function. You will be prompted to select which functions you want to deploy.
+
+### Manual using tar.gz
+
+Manual deployment has no requirements and uses Appwrite Console to deploy the tag. First, enter the folder of your function. Then, create a tarball of the whole folder and gzip it. After creating `.tar.gz` file, visit Appwrite Console, click on the `Deploy Tag` button and switch to the `Manual` tab. There, set the `entrypoint` to `src/mod.ts`, and upload the file we just generated.
