+### Before Write option
+
+This option allows you to preprocess a file before it is being written, such as running a formatter,
+linter or other commands.
+
+To use this option, pass it the command you would like to run. The following tokens will be replaced
+in your string:
+
+- `{{path}}` - the temporary file path for you to read from
+- `{{rawpath}}` - a different file path containing the raw file contents **before** they were
+  handled by Handlebars.js.
+
+If none of these tokens are found, the regular (non-raw) path will be appended to the end of the
+command.
+
+```shell
+simple-scaffold -c . --before-write prettier
+# command: prettier /tmp/somefile
+
+simple-scaffold -c . --before-write 'cat {{path}} | my-linter'
+# command: cat /tmp/somefile | my-linter
+```
+
+The command should return the string to write to the file through standard output (stdout), and not
+re-write the tmp file as it is not used for writing. Returning an empty string (after trimming) will
+discard the result and write the original file contents.
+
+See
+[beforeWrite](https://chenasraf.github.io/simple-scaffold/docs/api/interfaces/ScaffoldConfig#beforewrite)
+Node.js API for more details. Instead of returning `undefined` to keep the default behavior, you can
+output `''` for the same effect.

+### Before Write option
+
+This option allows you to preprocess a file before it is being written, such as running a formatter,
+linter or other commands.
+
+To use this option, you can run any async/blocking command, and return a string as the final output
+to be used as the file contents.
+
+Returning `undefined` will keep the file contents as-is, after normal Handlebars.js procesing by
+Simple Scaffold.
