# JianZiPu Font > JianZiPu (减字谱) is a font for guqin tablature: you type a short code such as `s7k5` (or 名七勾五) and the font swaps each piece for a drawn part and stacks them into one 减字 character. The JZP Font Builder is the web app where the font is made: the drawn parts (glyphs), how each part is typed (spellings), and how the parts sit together (layouts). The Builder (https://builder.jianzipufont.com) runs in the browser and asks testers to sign in, so its pages can't be read without one. Its help is published here instead. ## Docs - [Builder help, full text](https://jianzipufont.com/help.md): every screen, how words are typed, saving, drafts, keyboard shortcuts, and what each message means and how to fix it - [Builder help, with screenshots](https://jianzipufont.com/help/) - [The JianZiPu font](https://jianzipufont.com/): download, and the typing guide (layout, numbers and decimals, modifiers, chords, vertical text, glossary) ## Help sections - [Getting started](https://jianzipufont.com/help/#start) - [How words are typed](https://jianzipufont.com/help/#typing) - [Glyphs](https://jianzipufont.com/help/#glyphs) - [The glyph editor](https://jianzipufont.com/help/#editor) - [Layouts](https://jianzipufont.com/help/#layouts) - [Build & test](https://jianzipufont.com/help/#build) - [Saving and undo](https://jianzipufont.com/help/#saving) - [Your draft (online)](https://jianzipufont.com/help/#draft) - [Change Requests](https://jianzipufont.com/help/#requests) - [Reviewing Change Requests](https://jianzipufont.com/help/#review) - [Making a release](https://jianzipufont.com/help/#release) - [Keyboard shortcuts](https://jianzipufont.com/help/#keys) - [When something looks wrong](https://jianzipufont.com/help/#trouble) - [Messages and errors](https://jianzipufont.com/help/#messages)
