-# xbit
-`xbit` (xkcd backward in time) is a program for outputting historical events
-while completing a task, inspired by [xkcd](https://xkcd.com/1017). The program
-reads a SQLite database that stores event descriptions and timestamps, allowing
-you to easily add your own events of interest.
-
-The provided SQL file will pre-populate the database with thousands of events
-scraped from
-[Wikipedia](https://en.wikipedia.org/wiki/Detailed_logarithmic_timeline). Of
-these events, over 300 were manually given timestamps.
-
-## How to use
-First create the database:
-```
-sqlite3 timeline.db < timeline.sql
-```
-
-Then set the `XBIT_DB` environment variable to the database file.
-```
-export XBIT_DB=./timeline.db
-```
-
-Call the program with `xbit -p <percentage>`, like `xbit -p 0.25`. This will
-calculate a timestamp using the formula from the xkcd comic, then output
-information about the event in the database closest to that timestamp. See
-`xbit -h` for more args.
-
-## Database details
-* Due to the time-consuming nature of manually assigning timestamps, there are
-  many events that were scraped from Wikipedia but not given timestamps. You
-may wish to skim through these and add timestamps to events you personally find
-interesting.
-* For an event to be output by `xbit`, it must have an entry in the database
-  with a unix timestamp of when the event occured. You can optionally set bools
-in the "known" columns to indicate how precise your timestamp is. These may be
-used to modify how the event is output.
-* There are a few other columns that mainly exist as artifacts from the
-  scraping process. These are not used by `xbit` and do not need to be
-populated.
