+## Installation
+
+You can install rsthemes from GitHub with:
+
+``` r
+# install.packages("devtools")
+devtools::install_github("gadenbuie/rsthemes")
+```
+
+Then, install the included themes with:
+
+``` r
+rsthemes::install_rsthemes()
+```
+
+## Usage
+
+The rsthemes package includes a couple helper functions for exploring the themes.
+
+``` r
+# list installed themes
+rsthemes::list_rsthemes()
+
+# Try all themes
+rsthemes::try_rsthemes()
+
+# Try just the light, dark, or base16 themes, e.g.
+rsthemes::try_rsthemes("light")
+```
+
+Use `rstudioapi::applyTheme()` to activate a theme from the R console, or use *Tools* > *Global Options* > *Appearance* to interactively select a theme. 
+
+``` r
+# Use a theme
+rstudioapi::applyTheme("One Dark {rsthemes}")
+```
+
+## Uninstall
+
+If you want to uninstall all or some of the themes, you can use
+
+``` r
+rsthemes::remove_rsthemes()
+
+# or just the base16 themes, e.g.
+rsthemes::remove_rsthemes("base16")
+```
