-# Callaba On-Premise Installation on Linux
+# Callaba On-Premise 8.1 Installation
 
 ## Requirements
 
 - Ubuntu 22.04
 - Docker
 
-## Preparation
+## Step 1. Preparation
 
 - Clone the repository:
   ```console
-  git clone https://gitlab.callabacloud.com/callaba-8/linux.git
+  git clone https://gitlab.callabacloud.com/callaba-8/linux-8.1.git
   ```
 
 - Navigate to the folder:
   ```console
-  cd linux/
+  cd linux-8.1/
   ```
 
 - Update packages and install requirements. If the machine is clean, you can simply run:
   ```console
-  bash prepare.sh
+  sudo bash prepare.sh
   ```
 
-## Installation
+## Step 2. Installation with regular CPU transcoding usage
 
 After the requirements are installed, run the installation script. When prompted, enter your login and password for the registry:
 ```console
-bash install.sh
+sudo bash install.sh 8.1.NDI.pre
 ```
 
-## Update
+## Or installation with NVIDIA GPU support
+
+After the requirements are installed, run the installation script. When prompted, enter your login and password for the registry:
+```console
+sudo bash install.sh 8.1.NDI.pre nvidia
+```
+
+## Or installation with XILINX accelerated transcoding support
+
+After the requirements are installed, run the installation script. When prompted, enter your login and password for the registry:
+```console
+sudo bash install.sh 8.1.NDI.pre xilinx
+```
+
+
+## Step 3. Launch Callaba Dashboard
+After installation, please wait 2-3 minutes for the dashboard to initialize. It will be available at [http://127.0.0.1:80](http://127.0.0.1:80).
+
+![Image Description](./dashboard.png)
+
+
+## Step 4. Login to Callaba Dashboard
+By default, the login and password are `admin/password`. To purchase a license, use your [personal account](https://callaba.io/auth/sign-in) for on-premise.
+
+
+## Update or downgrade
 
 To update Callaba, run the following command:
 ```console
-bash update.sh
+sudo bash install.sh VERSION GPU_TYPE (nvidia | xilinx or cpu)
 ```
 
-## Rollback
 
-If something goes wrong, rollback the application using:
-```console
-bash rollback.sh
-```
-
-## Removal
+## Uninstall
 
 To remove Callaba, run the following command. **Note:** This will delete all data and images:
 ```console
-bash remove.sh
+sudo bash remove.sh
+```
+
+## Reset password
+
+To reset Callaba password, run the following command:
+```console
+sudo bash remove.sh
+```
+
+## Contact support
+Use the **Contact Support** button directly from your dashboard.
