+---@brief
+---Nvim includes a function for highlighting a selection on yank.
+---
+---To enable it, add the following to your `init.vim`:
+---<pre>vim
+---    au TextYankPost * silent! lua vim.highlight.on_yank()
+---</pre>
+---
+---You can customize the highlight group and the duration of
+---the highlight via:
+---<pre>vim
+---    au TextYankPost * silent! lua vim.highlight.on_yank {higroup="IncSearch", timeout=150}
+---</pre>
+---
+---If you want to exclude visual selections from highlighting on yank, use:
+---<pre>vim
+---    au TextYankPost * silent! lua vim.highlight.on_yank {on_visual=false}
+---</pre>
+---
+--- <pre>help
+---vim.highlight.priorities                            *vim.highlight.priorities*
+---
+---    Table with default priorities used for highlighting:
+---        • `syntax`: `50`, used for standard syntax highlighting
+---        • `treesitter`: `100`, used for tree-sitter-based highlighting
+---        • `semantic_tokens`: `125`, used for LSP semantic token highlighting
+---        • `diagnostics`: `150`, used for code analysis such as diagnostics
+---        • `user`: `200`, used for user-triggered highlights such as LSP document
+---          symbols or `on_yank` autocommands
+---</pre>
