LibreOffice includes many sample documents and ready-to-use templates. You can access these by choosing File - New - Templates, or press Shift+CommandCtrl+N.
जब तपाईँले कुनै एउटा टेम्प्लेट खोल्नुहुन्छ, एउटा नयाँ कागजात सिर्जना हुन्छ।
Click the Browse online templates button in the dialog to select and download more templates.
You can also use the various wizards (under the File - Wizards menu) to create your own templates, which you can use as a basis for further documents.
