+My collection of bash scripts.
+
+## Tools
+
+### create-package
+
+A tool to create new package directories with bash script templates.
+
+**Usage:**
+
+```bash
+# Using command-line arguments
+./create-package "My Tool"
+
+# Using stdin (piped input)
+echo "My Tool" | ./create-package
+```
+
+**Behavior:**
+
+- Creates a directory with the sanitized package name
+- Generates an executable bash script inside the directory with the same name
+- The generated script includes a shebang, error handling, and a simple hello message
+
+**Name Sanitization Rules:**
+
+Package names are automatically sanitized:
+- Converted to lowercase
+- Spaces and underscores are replaced with dashes
+- Only `[a-z0-9-]` characters are retained (letters, numbers, dashes)
+- Multiple consecutive dashes are collapsed into one
+- Leading and trailing dashes are removed
+
+**Examples:**
+
+```bash
+# Creates: my-tool/my-tool
+./create-package "My Tool"
+
+# Creates: hello-world/hello-world
+echo "Hello_World" | ./create-package
+
+# Creates: test123/test123
+./create-package "test123"
+```
+
+**Error Handling:**
+
+- If the sanitized name is empty (e.g., only special characters), the script exits with an error
+- If a directory with that name already exists, the script exits with an error message
