Redirect to docs from landing page in docusaurus v2

Since I don't have a landing page, I would like to redirect to the main doc page docs/main

I tried to follow the instructions: https://docusaurus.io/docs/en/site-creation#docs-landing-page from v1, but they don't seem to work for v2. Can someone please give me detail instructions on how to accomplish this?

I have very limited experience with React.
