-### Project ID
+## Usage
 
-The `project-id` is provided as a command-line argument. If no `project-id` is provided, the application will list all available projects.
+After building (and optionally installing), you can run the application.
+
+**IMPORTANT:** Flags must come **BEFORE** the project ID.
+
+### Filtering by Status
+
+You can filter issues by their status name or ID using comma-separated values.
+
+-   **`-status`**: Only include issues with these statuses.
+-   **`-exclude-status`**: Exclude issues with these statuses.
+
+Examples:
+```bash
+# Exclude "Done" and "Closed" issues
+redmine-tree -exclude-status="Done,Closed" my-project-id
+
+# Only show "New" and "In Progress" issues
+redmine-tree -status="New,In Progress" my-project-id
+
+# Mix and match (IDs work too)
+redmine-tree -status="In Progress" -exclude-status="5" my-project-id
+```
+
+### Basic Commands
