+@defvr {Scheme Variable} home-files-service-type
+The service of this type allows to specify a list of files, which will
+go to @file{~/.guix-home/files}, usually this directory contains
+configuration files (to be more precise it contains symlinks to files in
+@file{/gnu/store}), which should be placed in @file{$XDG_CONFIG_DIR} or
+in rare cases in @file{$HOME}. It accepts extension values in the
+following format:
+
+@lisp
+`((".sway/config" ,sway-file-like-object)
+ (".tmux.conf" ,(local-file "./tmux.conf")))
+@end lisp
+
+Each nested list contains two values: a subdirectory and file-like
+object. After building a home environment @file{~/.guix-home/files}
+will be populated with apropiate content and all nested directories will
+be created accordingly, however, those files won't go any further until
+some other service will do it. By default a
+@code{home-symlink-manager-service-type}, which creates necessary
+symlinks in home folder to files from @file{~/.guix-home/files} and
+backs up already existing, but clashing configs and other things, is a
+part of essential home services (enabled by default), but it's possible
+to use alternative services to implement more advanced use cases like
+read-only home. Feel free to experiment and share your results.

+@defvr {Scheme Variable} home-xdg-configuration-files-service-type
+The service is very similiar to @code{home-files-service-type} (and
+actually extends it), but used for defining files, which will go to
+@file{~/.guix-home/files/.config}, which will be symlinked to
+@file{$XDG_CONFIG_DIR} by @code{home-symlink-manager-service-type} (for
+example) during activation. It accepts extension values in the
+following format:
+
+@lisp
+`(("sway/config" ,sway-file-like-object)
+ ;; -> ~/.guix-home/files/.config/sway/config
+ ;; -> $XDG_CONFIG_DIR/sway/config (by symlink-manager)

@defvr {Scheme Variable} home-activation-service-type
The service of this type generates a guile script, which runs on every
@command{guix home reconfigure} invocation or any other action, which
leads to the activation of the home environment.
@end defvr
+@defvr {Scheme Variable} home-symlink-manager-service-type
+The service of this type generates a guile script, which will be
+executed during activation of home environment, and do a few following
+steps:
+
+@enumerate
+@item
+Reads the content of @file{files/} directory of current and pending home
+environments.
+
+@item
+Cleans up all symlinks created by symlink-manager on previous
+activation. Also, sub-directories, which become empty also will be
+cleaned up.
+
+@item
+Creates new symlinks the following way: It looks @file{files/} directory
+(usually defined with @code{home-files-service-type},
+@code{home-xdg-configuration-files-service-type} and maybe some others),
+takes the files from @file{files/.config/} subdirectory and put
+respective links in @env{XDG_CONFIG_DIR}. For example symlink for
+@file{files/.config/sway/config} will end up in
+@file{$XDG_CONFIG_DIR/sway/config}. The rest files in @file{files/}
+outside of @file{files/.config/} subdirectory will be treated slightly
+different: symlink will just go to @file{$HOME}.
+@file{files/.some-program/config} will end up in
+@file{$HOME/.some-program/config}.
+
+@item
+If some sub-directories are missing, they will be created.
+
+@item
+If there is a clashing files on the way, they will be backed up.
