+# find-root-ca-cert
+
+Node package to find the OS-installed root CA certificates. This uses the same location list as go. Based upon this [this answer](https://serverfault.com/a/722646) on ServerFault.
+
+## Installation
+
+`npm install --save find-root-ca-cert`
+
+## Usage
+
+```js
+const certFinder = require("find-root-ca-cert");
+certFinder.findCAPath();
+// /etc/ssl/certs/ca-certificates.crt
+certFinder.findCABundle();
+// /etc/ssl/certs/ca-certificates.crt
