 ## Example
 
-This is a basic example which shows you how to solve a common problem:
+This is a basic example which shows the the 6-year probability of lung cancer in an individual person. The example is an individual who is 62 years old, white, had some college (level 4) education, with body-mass index 27, no chronic obstructive pulmonary disease, no personal history of cancer, no family history of lung cancer, former smoker, smokes 80 cigarettes per day, smokes for 27 years and quits smoking for 10 years.

-You’ll still need to render `README.Rmd` regularly, to keep `README.md`
-up-to-date. `devtools::build_readme()` is handy for this. You could also
-use GitHub Actions to re-render `README.Rmd` every time you push. An
-example workflow can be found here:
-<https://github.com/r-lib/actions/tree/master/examples>.
-
-You can also embed plots, for example:
-
-<img src="man/figures/README-pressure-1.png" width="100%" />
-
-In that case, don’t forget to commit and push the resulting figure
-files, so they display on GitHub and CRAN.
