 ## Features
 
 For now, `bibiman` only has some very basic features implemented which are
-important for my personal workflow:
-
-- **Browse** through the bib entries using _Vim-like keybindings_ and a _fuzzy
-  search_ mode.
-- **Filter** the bib entries by _keywords_ (and afterwards filter further by
-  fuzzy searching).
-- **Edit** the current entry by opening a _terminal-based editor_ at the
-  specific line
-- **Yank/Copy** the citekey of the current entry to the system clipboard.
-
-Furthermore, I want to implement the following features:
-
-- [ ] **Open PDF**: Open related PDF file (`file` BibLaTeX key) with keypress.
-- [ ] **Open URL/DOI**: Open related DOI/URL with keypress.

+For selecting the right program, it uses `xdg-open` on Linux, `open` on MacOS,
