How to add an item in a blog post's sidebar?

[CLOVIS-AI]

I have recently added support for RSS in my blog. I'd to like to emphasize this to readers, by adding a link to the RSS feed in the post's sidebar, alongside its existing metadata.

My understanding is that I should do this by overriding the blog-post.html template to be able to add new information. However, to do this, I would need the sidebar to be in its own block, no? And it doesn't appear to be.

So, how can I add a new item in a post's sidebar?

Hello @CLOVIS-AI,
you're correct, there is no block for overrides defined in that template, the theme limits the blocks only to base.html.
Basically you have to copy the whole content of the template and modify the HTML to your liking, as it overrides the container block.
Name it blog-post.html so that your overridden variant will overwrite the file from the theme, during build.
