 # Alpha Project Manager
 
-An Infrastructure as Code manager to deploy lab infrastructure. Working with Atrium, Gitlab CI, Terraform, Cloud-init and Scaleway.
+An Infrastructure as Code manager to deploy lab infrastructure and configure instances. Working with Atrium, Gitlab CI, Terraform, Cloud-init and Scaleway.
 
 ### How does it work ?
 
+The FORGE (Gitlab) manage Terraform at any state, plan, creation, modification and destruction with the CI. The FORGE store and will provide the configuration information
+such as credentials to Terraform only during the running state to improve security, then information are destroyed with the container of the Gitlab Agent.
+
+On run state, Terraform will create, modify and destroy infrastructure resources in Scaleway to match the configuration described in the configuration files.
+After the resources provisionned with Terraform, Cloud-init will configure the instances by running bash scripts, creating files... And 3 services will be running for each instance :
+- Atrium (Reverse proxy, TLS encryption and HTTPS to the others hosted services)
+- Code-server
+- Webtop
+
+After deployment, each resource can be accessed though HTTPS depending their count number :
+- https://desktop-0.lab-0-devrust.daag.alpha.grandlyon.com/
+- https://code-0.lab-0-devrust.daag.alpha.grandlyon.com/
+- 
+
+Resources deployed :
+
+| resource-type                    | plan   | inbound port |
+|----------------------------------|--------|--------------|
+| scaleway_instance_ip             |        |              |
+| scaleway_domain_record           |        |              |
+| scaleway_domain_record           |        |              |
+| scaleway_instance_security_group |        | 22, 443, 80  |
+| scaleway_instance_server         | DEV1-L |              |
+
 At first, Gitlab CI will run scripts to generate environment variables.
 They will be used in Terraform for configuration and securing credentials.
