+# Tecnalia smartdatalab ca
+
+## Objective
+
+This is an **autogenerated** ca for tecnalia internal use, the purpose is to avoid disgusting security screens in our systems and projects. We will use this ca to sign certificates for our internal systems, so that we avoid security warnings and we could enable internal trust relationships.
+
+## How to create certificates based on it
+
+To create certificates based on it for the moment we have to do manually, to do so you can use the private key stored in the private repository  
+
+## How to install the certificate
+The instalation of the certificate depends both on the operating system and in some cases on the specific application. There are some applications, such as firefox, that does not relay in the operating system certificates repository to validate incoming certificates.
+
+### Windows

+set CA_FILE_PATH=%TEMP%ca.crt.pem
+echo download ca
+powershell -command "$cli = New-Object System.Net.WebClient; $cli.DownloadFile('%CA_RAW_URL%', '%CA_FILE_PATH%')"
