-Here's a step-by-step guide to setting up and using your BrainArchive system in Obsidian, based on the provided details:
+Here's a shell script that takes a variable named `vault_name` in Python case to create the directory structure for your BrainArchive system:
+
+```bash
+#!/bin/bash
+
+# Define the default vault name
+default_vault_name="BrainArchive"
+
+# Use the provided vault name or fall back to the default
+vault_name="${1:-$default_vault_name}"
+
+# Create the main directory structure
+mkdir -p "$vault_name/Inbox"
+mkdir -p "$vault_name/Notes/Personal"
+mkdir -p "$vault_name/Notes/Work"
+mkdir -p "$vault_name/Notes/Projects"
+mkdir -p "$vault_name/Notes/Research"
+mkdir -p "$vault_name/Notes/Learning"
+mkdir -p "$vault_name/Notes/Hobbies"
+mkdir -p "$vault_name/Notes/Reference"
+mkdir -p "$vault_name/Notes/Food"
+mkdir -p "$vault_name/Notes/Tech"
+mkdir -p "$vault_name/Templates"
+
+echo "Directory structure for $vault_name created successfully."
+```
+
+### Instructions to Use the Script:
+
+1. Save the script as `create_vault_structure.sh`.
+2. Make the script executable:
+   ```bash
+   chmod +x create_vault_structure.sh
+   ```
+3. Run the script with the desired vault name or let it use the default name:
+   ```bash
+   ./create_vault_structure.sh
+   ```
+   Or specify a custom vault name:
+   ```bash
+   ./create_vault_structure.sh MyCustomVault
+   ```
+
+If no vault name is provided, the script will use "BrainArchive" as the default vault name.
