+## Configuration loader directives
+
+The loader which is responsible for loading configuration files supports
+some directives which can be handy in some situations, .e.g in case
+multi-file configuration is used.
+
+Directives are started with hash `#` and followed with the name of the
+directive and zero, one or many arguments. For example,
+`#include extra/user.cfg`.
+
+### Including files
+
+The loader can be instructed to load other configuration file(s) with
+directive `#include`. The directive requires loading files to exist what
+means if the loader fails loading one of including files it will fail
+loading the whole configuration.
+
+The syntax of the directive is `#include <path>` where `<path>` is the relative
+or absolute path to the file which should be loaded,
+e.g. `#include db.cfg`, `#include /etc/my_tool/extra.cfg`. The path
+can contain globs (or wildcards), e.g. `#include user/*.cfg`.
+
+Please notice that all relative paths are relative to the main file path,
+the path you passed into `config.Read()` or `config.ReadDefault()`.
