+## Installation

+You can install {updateme} from CRAN like so:
+``` r
+install.packages("updateme")
+```

 ## What's in the box?
 
 {updateme} modifies `library()` to tell you if your packages are up to date when
 you load them:

 {updateme} works with packages installed from CRAN (and CRAN-like repos),
 Bioconductor, GitHub and GitLab. Packages installed from Bioconductor are
 intelligently checked against the version of Bioconductor you're using, and 
 these get a special message if they're more recent than they probably should be:

 The tidyverse is a special case, which gets its own modified startup message:

 {updateme} is configurable using
 [`updateme_sources_set()`](https://wurli.github.io/updateme/reference/updateme_sources_set.html). If, for example, you're using the development version of {lubridate} but you'd 
 like to see which version is currently on CRAN, you can get this behaviour like 
 so:

 By default, {updateme} will check for new versions of a given package from 
 wherever your version seems to have been installed from.

 ### Caching
 
 Some caching of downloads is used to make most calls to `library()` pretty
-quick. The cache resets every hour, but you can configure this like so:
