This is a post. It lives in its own folder:
content/posts/hello-world/
index.md <- this file
(images go here too)
Everything about a post lives in that one folder, which means adding a picture is just uploading it here and writing its filename. No paths to get right.
Adding a picture
Upload the image into this folder, then write:

That is the whole thing. The text in the square brackets is what screen readers read out and what shows if the image fails to load, so it is worth writing.
Formatting
Regular Markdown works:
- bold with
**bold** - italic with
*italic* - a link with
[link](https://example.com)
Quotes look like this.
The bit at the top
The block between the +++ lines is the post’s settings. Only title really
matters. date controls the ordering, description is the grey line shown in
the post list, and tags are optional.
To hide a post while you work on it, add draft = true under the title. It will
not appear on the site until you remove that line.
