-- Custom upload parameters (expiry time, download limit)
+
+## Feature Details
+
+### Custom Upload Parameters
+
+The app allows you to customize how your uploads are handled on the server:
+
+#### Maximum Downloads
+
+- **Purpose**: Limit how many times a file can be downloaded
+- **Default**: 1 download (file is removed after first download)
+- **Options**: 
+  - Set to any positive number to limit downloads
+  - Set to 0 for unlimited downloads
+- **How to use**: Enter your desired number in the "Maximum Downloads" field when uploading a file
+
+#### Expiry Time
+
+- **Purpose**: Set how long the file remains available on the server
+- **Default**: 24 hours (1 day)
+- **Maximum**: 24 hours (server-enforced limit)
+- **How to use**: Enter your desired number of hours in the "Expiry Time" field when uploading
+
+#### Upload Parameter Dialog
+
+When you initiate an upload (either a selected file or dumpstate), the app will present a dialog where you can set these parameters before the actual upload begins. If you don't modify the fields, the default values will be used.
+
+### Server-Side File Deletion
+
+The app integrates with the server's delete endpoint to remove files from the server when you delete them from your local history.
+
+#### Single Item Deletion
+
+When you delete a single item from your upload history:
+1. The app attempts to delete the file from the server using its upload code
+2. Regardless of server response, the item is removed from your local history
+3. You will receive feedback about whether the server deletion was successful
+
+#### Bulk Deletion (Clear History)
+
+When you clear all history:
+1. The app attempts to delete each file from the server
+2. All items are removed from your local history
+3. You will receive feedback about whether any of the server deletions were successful
+
+#### Benefits
+
+- **Privacy**: Ensures your uploaded files don't remain on the server indefinitely
+- **Resource Management**: Helps keep the server storage clean
+- **Control**: Gives you full control over the lifecycle of your uploaded files
+
+#### API Integration
+
+The app uses the server's delete endpoint:
+```
+DELETE /delete/<code>
+```
+
+This endpoint requires the same client authentication key used for uploads. The server returns:
+- 200 OK: File successfully deleted
+- 404 Not Found: File doesn't exist (already deleted or expired)
+- 401 Unauthorized: Invalid client key
