+This is probably the first thing that needs to be customized, since it points to a different identity for each git user.
 I sign all my commits by default, so take out the corresponding lines if you don't, or exchange it with your gpg key.
-Similarly for jujutsu, change the identity and remove the lines concerning gpg signing if you don't use it.
 
 Git will rewrite any remotes using http(s) to use the ssh notation for pushes to github and gitlab so that, even if you set up the repository using an https url you can utilize your usual ssh key for pushing.

 [zathura](git.pwmt.org) - keyboard-driven PDF reading
 [sioyek](http://sioyek.info/) - keyboard-driven PDF reading *and annotating*
+
+This readme is a little out of date, as are the scripts below.
+They are old, I used them during my time as a student and they are probably written terribly.
+But I still think there is value in them, hence not removing them from the repo just yet.
+
+## bib-due
+
+The `bib-due` script depends on (gnu) grep, awk, and sed, date if using date filtering capabilities. It is currently written in a rather haphazard way, and prone to breakage.
+On the other hand, it does what it's supposed to do: list bibtex entries which have their due-date coming up.
+
+The script needs bibtex entries to be marked with two fields: `due`, containing a due date (ideally in YYYY-MM-DD format, for easy sorting), and `priority` containing a read priority. It will also, by default attempt to grab the values of the fields `author` and `title`, as well as the name of the bibtex key of the entry.
+
+It can be invoked with the path to a bibtex file `bib-due path/to/library.bib`, and will gather the entries from the respective file. It can be invoked without an argument if the environment variable `$BIBFILE` is declared (pointing to a bibtex file).
+
+Example output looks as follows:
+
+![bib-due example output](.assets/bibtex/list.png)
+
+The output can then be filtered further through other programs.
+
+Bib-due itself allows 2 filtering options: *until* a certain date (`-u`), and *at least* a certain priority (`-p`).
+
+Using priority is relatively self-explanatory: 1 is the highest priority, 3 the lowest (technically, no priority is the lowest). Choosing `-p3` means priority 1, 2, and 3 will be displayed. Choosing `-p1` will only display the highest priority items.
+
+Using the date works as a cut-off for the future, and it uses gnu `date` to calculate the correct date. That makes things like `-u 'fri this week'` possible, showing only upcoming items until the end of the week. Read the `date` manual for more information.
+There will likely not be a new option for filtering dates *from* a certain point forward since I don't need it and before implementing more stuff what's there should be more solid. (and read your damn overdue texts!)
+
+Again, this script will (for now[^time]) break when bibtex files are formatted in any way other than what it expects.
+An example of a working entry:
+
+[^time]: And probably for some time since I don't see myself sinking too much more time into this in the near future. I actually need to get some of the upcoming readings done that I can now list! 🙂
+
+```
+@InBook{Borhi2016,
+  author    = {László Borhi},
+  chapter   = {1956: Self-Liberation},
+  pages     = {117--137},
+  publisher = {Indiana University Press},
+  title     = {Dealing with dictators: the {United States}, {Hungary}, and {East Central Europe}, 1942-1989},
+  year      = {2016},
+  due       = {2020-05-07},
+  file      = {:Borhi2016 - Dealing with Dictators_ the United States, Hungary, and East Central Europe, 1942 1989.pdf:PDF},
+  pagetotal = {564},
+  priority  = {prio1},
+  timestamp = {2020-05-08},
+}
+```
+
+Important fields are author, title, due, priority. These need to exist, and need to be ordered alphabetically. Otherwise there will probably be some breakage.
+
+## rofi-bib-due
+
+The `rofi-bib-due` script utilizes the `bib-due` script and depends on an existing installed `rofi` module (see [here](rofi/)).
+On invocation, it creates a list of upcoming readings, and allows selecting one of the readings. The selected reading will be passed along to `$FILEREADER` if it is declared, falling back to `xdg-open` if not.
+
+Currently, the path to the reading pdf is hard-coded to be `path/to/bibtex.bib/pdf`, and the name has to begin with the exact bibtex key; otherwise the script will not be able to find the pdf.
+
+An example of the script in action: (window size has been reduced for the recording, cutting off most entry names)
