What next?

If you have downloaded Zettlr, head over to our website to get to know Zettlr. Refer to the Quick Start Guide, if you prefer to use software heads-on.



To start developing, simply git clone and npm install the app on your local computer:

$ git clone https://github.com/Zettlr/Zettlr.git
$ cd Zettlr
$ yarn install
$ cd source
$ yarn install

(Please note the second yarn install in the source directory. This is necessary if you want to build the app locally.)

If you use npm, this is also supported.

To explore the functionality and inner workings of the app, head over to our development documentation!

Before your first yarn start and everytime you’ve made changes to either the LESS-files or the templates, you need to run:

$ yarn less
$ yarn handlebars

to compile both the style sheets and the precompiled handlebars.js templates.
