I found two great tutorials using Hugo to build your own website and then publish on either GitHub or Netlify.
Publish on github with Hugo directly: https://youtu.be/3wkR8GyDODs
Publish on Netlify with Blogdown: https://alison.rbind.io/post/up-and-running-with-blogdown/
One update for the 2nd tutorial is that for build command: https://www.netlify.com/docs/continuous-deployment/#common-configuration-directives
For Hugo hosting, the build command hugo will build and deploy with the version 0.17 of Hugo. For versions 0.13, 0.14, 0.15, 0.16, 0.17, 0.18 and 0.19, you can specify a specific Hugo release like this: hugo_0.15. For version 0.20 and above, use the regular hugo command and create a Build Environment Variable called HUGO_VERSION and set it to the version of your choice. (More details can be found on our blog.)
For me, I am using hugo v0.29, so I cannot use hugo_0.29 as the command; instead I need to just use hugo as the command, and create a Build Environment Variable called HUGO_VERSION and set the value 0.29. This can be done in the setting page.
