+For PHP 7.1 and up GALLERY_FS_ENCODING and `$fsEncoding` parameter of the constructor are ignored.
 
 Starting from PHP 7.1, [PHP uses internal_encoding to transcode file names](https://github.com/php/php-src/blob/e33ec61f9c1baa73bfe1b03b8c48a824ab2a867e/UPGRADING#L418).
 Before that, file IO under Windows (notably) done using "default" (so-called "ANSI") character set (i.e. CP1251 for Russian cyrillic).

+## Compiling single file archive
+
+```
+pharcommand.phar pack -f mlg.phar -s stub.php -c bzip2 index.php Gallery.php
+```
+
+Afterwards, the resulting `mlg.phar` can be used as index.php in your web gallery directory.
+You may want to place config.php next to it to configure the gallery.
+By default, it will list all recognized image files in current directory using UTF-8 encoding.
