Migrate Hugo blog repository (but delete all Git commits)

My real case

• Migrate repository from BitBucket to GitHub.
• I could delete Commit histories.

What I’ve done

1. Update .gitignore.
2. Delete docs directory.
3. Update netlify.toml

[build]
publish = "docs"
command = "hugo --gc --minify"

[context.production.environment]
  HUGO_VERSION = "0.87.0"

1. rm -rf data #old dir structure
2. rm -rf .git
3. rm -rf theme/mainroad
4. git init
5. git submodule add git@github.com:Vimux/Mainroad.git themes/mainroad
6. git config --global user.name atlex00
7. git config --global user.email ...
8. git commit
9. git push origin master --force
