+## Formatter
+
+If `coc-prettier` (v9.2.0 later) is installed, `prettier` will be run as the formatter.
+
+If you want to use the volar's built-in formatter, set `prettier.formatterPriority` to `-1` in `.vim/coc-settings.json`.
+
+```jsonc
+{
+  "prettier.formatterPriority": -1,
+}
+```
+
+Or set `prettier.disableLanguages` to `vue` in `.vim/coc-settings.json`.
+
+```jsonc
+{
+  "prettier.disableLanguages": [
+    "vue"
+  ]
+}
+```
+
+It can also be controlled by other `coc-prettier` settings and `.prettierignore` files.
+
+Check the README of `coc-prettier` for details. <https://github.com/neoclide/coc-prettier/blob/master/Readme.md>
