+# CORS middleware
+
+This example shows how you can add a CORS middleware to your API.
+
+This is useful when making cross-origin requests from the browser (client-side).
+
+# Run API
+
+1. `cd` into the `14_cors/` dir:
+
+   ```bash
+   cd 14_cors/
+   ```
+1. Fire up R and restore package dependencies:
+
+   ```r
+   renv::restore()
+   ```
+1. `server.R` is the entry point. Run this command in the terminal to start the API:
+
+   ```bash
+   Rscript server.R
+   ```
