Hi @mmcky, do we have an instruction on how to preview any staged changes?

I tried to open the html file directly in my browser but this doesn't work.

Many thanks :D

@HengchengZhang there are no preview builds on the website.

You can build locally using Jekyll

https://jekyllrb.com

and there are some quick start instructions there for the page to be served on your system.

Thank a lot @mmcky! I will have a look now.

@HengchengZhang once you get up and running maybe you can

• [ ] add a page to QuantEcon.manual for building the website locally.
