This is a command-line program designed to make reading, writing and editing such as multi-file creative works (including those with complex directory structures) such as indexes, glossaries, and hypertext fiction from the command-line much easier. See ki -h or ki --help for more information. Also see the webpage for Ki: http://radishrain.321.s1.nabble.com/Ki-td3550.html
To install, make sure git and wget are installed, and then do git clone https://github.com/kumoshk/ki; cd ki; sudo python3 ki -u; python3 ki --xload xscheme.ki; cd ..; rm -fr ki, and follow the prompts. Omit sudo if you're on Termux or want a local installation. If you don't wish to delete the files created with git clone, then omit ; cd ..; rm -fr ki, of course.
