To build the presentation locally you will need to install marp-cli. Then you can create a rendition with a command below:
marp presentation.md
This will produce presentation.html
and you can just open it in the browser to present.
You can also present directly by adding -p
command argument:
marp -p presentation.md
Keep in mind that it requires a chromium based browser installed on your system.
You can read raw markdown rendition here
