Got started with Nikola. I used Wordpress for a loooong time, and now ready to explore this whole headless CMS territory.
Some notes for my reference here:
new posts: nikola new_post
edit post with VSCode
check it out locally, tweak until happy: nikola auto --browser
redundant step (because of auto above) but for clarity: nikola build : static site is generated and all goes into an "output" folder
sync the output folder to S3, giving it public access: aws s3 sync output s3://www.alfaj0r.com --acl public-read
