 * Introduction
 When collecting information using copy/paste, it would be useful if one could
-stay at one place to copy things instead of constantly switching between the
-place where you copy and the place where you paste.
+stay at one place to copy things and later insert them all at once at another
+place. Emacs has =append-next-kill= but it only works inside Emacs and it only
+applies to the very next command. Further it would be great if Emacs could
+detect specific clipboard entries and transform them to a different format
+automatically. =clipboard-collector= provides you with those features.
-Further it would be great if Emacs could detect clipboard entries and adjust
-them to the format one would like to have them.
+You can use it to simply collect multiple entries by binding
+=clipboard-collector-mode= to a key:
-This is what clipboard-collector is about. Here is an example for collecting
-contact information from a website for org capture (contact info gets
-transformed to be used as org property drawer items).
+#+BEGIN_SRC elisp
+(global-set-key (kbd "C-M-w") 'clipboard-collector-mode)
+Once called the clipboard is observed and any text that is copied/killed gets
+collected (even when done outside of Emacs). To finish use =C-c C-c= in any
+buffer to insert the collected items separated by newlines.
+If you want to have specific rules which items are added and maybe transform
+them before collecting them you can create you own commands using
+=clipboard-collector-create= macro.

+capture (contact info gets transformed to be used as org property drawer
