How to link to another page/post?

Ditto. I want to add a link, whether by the use of Markdown or HTML tags, from a post or page to another page within the same site. Something like this: [Introduction](/src/posts/introduction.md) or similar.

The link should be a URL path relative to your root domain, not a file path.

In this case, the generated URL for /src/posts/introduction.md will be https://your-domain.com/posts/introduction/, so the link here should be [Introduction](/posts/introduction/). If you have set the base, make sure to include it in the link as well.

Alternatively, you can try this plugin: https://github.com/vernak2539/astro-rehype-relative-markdown-links

Thanks! I experimented a bit, and got it to work. For anyone in the future that may encounter this same question...
To link from about.md to {my_file}.md, assuming the latter is in src/content/posts/, you have to use ../posts/{my_file}/.
If it's inside a folder, make sure to also include the folder, like ../posts/folder/{my_file}/.
To link from any post to another post, you have to use /{base}/posts/{my_file}/ or /{base}/posts/folder/{my_file}/, where {base} is the one you set in astro.config.mjs, just swap {base} with whatever you have set over there.

Again, thank you!
