 ## What is Semaphore UI
 
-Semaphore UI is a sleek web interface designed to manage and run tasks using tools like Ansible and Terraform, but also Bash, Powershell or even Python scripts.
+[Semaphore UI](https://semaphoreui.com/docs/) is a sleek web interface designed to manage and run tasks using tools like Ansible and Terraform, but also Bash, Powershell or even Python scripts.
+
+Initially began as Ansible Semaphore, a web interface created to provide a simple front-end for running solely Ansible playbooks. Over time the community evolved the project into a multi-tool automation control plane.
+
+It is a self-contained Go application with minimal dependencies capable of using different database backend, such as PostgreSQL, MySQL, or BoltDB. 
 
 ## Installation
 
+Semaphore UI supports many ways to [install](https://semaphoreui.com/docs/category/installation) it: Docker, Kubernetes, package manager or simple binary file.
+
+I'll use Docker for my installation, you can see how I deploy application currently in this [post]({{< ref "post/16-how-I-deploy-application" >}})
+
+Here my `docker-compose.yml` file I've configured using PostgreSQL:
+```yml
+services:
+  semaphore:
+    image: semaphoreui/semaphore:v2.16.45
+    container_name: semaphore_ui
+    environment:
+      - TZ=Europe/Paris

+
+To generate the encrypting access keys, I use this command:
+```bash
+head -c32 /dev/urandom | base64
