-## Icons
-
-pending.nvim renders task status and metadata using configurable icon characters. The defaults use plain unicode (no nerd font required):
-
-```lua
-vim.g.pending = {
-  icons = {
-    pending = '○', done = '✓', priority = '●',
-    header = '▸', due = '·', recur = '↺', category = '#',
-  },
-}
-```
-
-See `:help pending.Icons` for nerd font examples.
