### Highlights
As languages differ quite a lot, here is a set of captures available to you when building a `highlights.scm` query.
One important thing to note is that many of these capture groups are not supported by `neovim` for now, and will not have any
effect on highlighting. We will work on improving highlighting in the near future though.
As languages differ quite a lot, here is a set of captures available to you when building a `highlights.scm` query. Note that your colorscheme needs to define (or link) these captures as highlight groups.

#### Priority
Captures can be assigned a priority to control precedence of highlights via the
`#set! "priority" <number>` directive (see `:h treesitter-highlight-priority`).
The default priority for treesitter highlights is `100`; queries should only
set priorities between `90` and `120`, to avoid conflict with other sources of
highlighting (such as diagnostics or LSP semantic tokens).
