 Goes to the sci-hub page for the current article, based on DOI.
 
-Can be invoked with DOI on a page selected,
-through the hinting mode when selecting a DOI link
-or on a publisher page (any page where doi meta-tags are set) -
-works on ScienceDirect, Taylor&Francis, Springer, etc.
-
-Updates its sci-hub link based on the one listed on sci-hub wiki page.
 
 Based on the work in
 https://github.com/cadadr/configuration/blob/4b6a241d04d113f322b960890a0d0a0ab783a7b3/dotfiles/qutebrowser/userscripts/doi
 with much gratitude.
+
+The program can be invoked with DOI on a page selected, through the hinting mode when selecting a DOI link or on a publisher page (any page where doi meta-tags are set) - works on ScienceDirect, Taylor&Francis, Springer, etc.
+That means you can give it a doi through a link or on the current page, for example with the following mappings:
+
+```python
+config.bind('"p', "spawn --userscript doi2scihub")
+config.bind(';p', "hint links userscript doi2scihub")
+```
+
+You can also pass the doi as the (only) argument to the userscript:
+
+```
+:spawn --userscript doi2scihub https://doi.org/10.37394/23207.2021.18.68
+`
+
+Updates its sci-hub link based on the one listed on sci-hub wiki page.
