 # quarto (development version)
 
+* Add `profile` arguments to `quarto_render()` and `quarto_inspect()` (thanks, #95, @andrewheiss, #123, @salim-b).
+
 * Add `metadata` and `metadata_file` to `quarto_render()` to pass modify Quarto metadata from calling render. If both are set, `metadata` will be merged over `metadata_file` content. Internally, metadata will be passed as a `--metadata-file` to `quarto render` (thanks, @mcanouil, #52, @maelle, #49).
 
 * Added a `NEWS.md` file to track changes to the package.

+Quarto enables you to weave together content and executable code into a finished document. To learn more about Quarto see <https://quarto.org>.
+
+## Running Code
+
+When you click the **Render** button a document will be generated that includes both content and the output of embedded code. You can embed code like this:
+
+```{r}
+1 + 1
+```
+
+You can add options to executable code like this
+
+```{r}
+#| echo: false
+2 * 2
+```
+
+The `echo: false` option disables the printing of code (only output is displayed).
