 - Bad Hack to get the file back to the client (but maybe interesting in some ACI troubleshooting hacks, that is why I save this work here)
 - Overall maybe a not so ideal solution from a security perspective to save the SSL certificate locally and chain it back to the Terraform script.

+I will come up with a better more reproducible solution. But until then:
+
+```bash
+cd LetsEncrypt\Archive
+
+az group create -name rg-geobot-global -location japaneast
+
+.\IssueSSLCertificate.ps1 -YOUR_CERTIFICATE_EMAIL <YOUR_EMAIL> -YOUR_DOMAIN <BOT_NAME>.trafficmanager.net -BOT_NAME <BOT_NAME> -PFX_EXPORT_PASSWORD <PFX_EXPORT_PASSWORD>
+```
+
+Known issues/drawbacks/things to be reminded of for this script:
+
+- __the BotName has to be unique__ since several Azure services will use it as prefix. Stick to lowercase no dashes and special chars and less than 20char. e.g. **myfirstname1234**
+- due to a bug in the current setup a complex password with special characters **may not work** as expected
+- the Terraform script in [Step 3](#3-deploy-the-solution) was created before realizing the need of creating a trusted SSL certificate, we will already deploy the TrafficManager in this step. In order to match with the default values of the current Terraform script, the resource group `rg-geobot-global` and location `japaneast` are correct. If you modify these values of the Terraform script either delete it (the resource group) after Step 2 before running Step 3 or match the values accordingly
