Help with page not found

I’m following the steps highlighted in this repo:
https://github.com/nixentric/Lowkey-Hugo-Theme

Though i followed the same steps, once I use the command hugo server and open the browser, I could see Page not found on the browser.

I am unable to reproduce the problem.

hugo new site quickstart
cd quickstart
git init
git submodule add https://github.com/nixentric/Lowkey-Hugo-Theme themes/lowkey
rm -f hugo.toml || rm -f config.toml
cp -r themes/lowkey/ExampleSite/* .
npm install
hugo server

Then visit http://localhost:1313/

I followed the same steps but still ended up with the same error - Page not found

Then you have a different problem.

You are more likely to receive a prompt and accurate response if you post a link to the public repository for your project.

See Requesting Help.

Let us see your code

Include a link to the source code repository of your project, because we really need the context of seeing your templates and partials to be able to help you. It is trivial to do a quick git clone on your repo, then run hugo server in your project, to help you out. On the other hand, recreating your code from screenshots, or sort of guessing at it, is not.

If you can’t share your repository for whatever reason, consider creating a dummy repo that you can share, which reproduces the problem you’re experiencing.
