Getting blank page after rendering using hugo server -D

[soumya997]

Hey, @NormandErwan I followed the steps provided in the hugo site, but after opening it via localserver it is showing a blank page, with a message, which is this->
WARN 2021/06/01 17:50:48 found no layout file for "HTML" for kind "home": You should create a template file which matches Hugo Layouts Lookup Rules for this combination.

WARN 2021/06/01 18:16:02 found no layout file for "HTML" for kind "home": You should create a template file which matches Hugo Layouts Lookup Rules for this combination.

The steps that I followed,

1. hugo new site blog1
2. cd blog1
3. git init
4. git submodule addhttps://github.com/NormandErwan/Blogpaper.git themes/Blogpaper
5. Then copy-pasted all the files and folders that were present in the exampleSite folder.
6. made baseurl = ""
7. ran the command hugo server -D

I am using windows 10,
hugo version gives me hugo v0.82.0-9D960784 windows/amd64 BuildDate=2021-03-21T17:28:04Z VendorInfo=gohugoio

It will be very helpful if you can help. thank you🙇‍♂️.
