+### Fix cURL error 60 on Windows using XAMPP
+
+If you are working with XAMPP on Windows you will most likely get the following error during `october install`:
+
+    cURL error 60: SSL certificate problem: unable to get local issuer certificate
+    
+You can fix this error by executing the following steps.
+
+1. Download the `cacert.pem` file from [VersatilityWerks](https://gist.github.com/VersatilityWerks/5719158/download)
+2. Extract the `cacert.pem` to the `php` folder in your xampp directory (eg. `c:\xampp\php`)
+3. Edit your `php.ini` (`C:\xampp\php\php.ini`). Add the following line.
+
+   `curl.cainfo = "\xampp\php\cacert.pem"`
+
+`october install` should work now as expected.
