+## Installation
+
+You can install the development version of vchartr from [GitHub](https://github.com/dreamRs/vchartr) with:
+
+```r
+# install.packages("remotes")
+remotes::install_github("dreamRs/vchartr")

+
+## Overview
+
+The following graphs (and more) can be produced:
+
+![charts-overview](figures/vchart-types.png)
+
+
+
+## Usage
+
+Start by initializing a chart with the `vchart()` function, then choose the appropriate function according to the type of chart you wish to make and specify the variables to be used as aesthetics:
+
+```r
+vchart(eco2mix) %>% 
+  v_line(aes(date, solar))
+```
