Documentation for https://zato.io/docs
Each major Zato release has its own subdirectory, for instance, 2.0 or 3.0.
To build HTML documentation (here, 3.0):
$ cd ~
$ git clone https://github.com/zatosource/zato-docs.git
$ cd ~/zato-docs/3.0/sphinx
$ make virtualenv
$ make html
Now the output HTML is in ~/zato-docs/3.0/sphinx/_build/html/index.html
.
