 - Upload custom scenarios from your local machine
 
 ## Installation
-Before attempting to install this GUI, make sure you've successfully installed SteamCMD and Arma 3 dedicated server. 
-You can follow [this guide](https://community.bistudio.com/wiki/Arma_3_Dedicated_Server). 
 
-After you have your SteamCMD and Arma 3 dedicated server working, either download the GUI jar file or build it from the
-source using `gradle assemble`.
+### Prerequisites
+- [JDK 17](https://www.oracle.com/java/technologies/downloads/#java17)
+- [Docker](https://docs.docker.com/engine/install/) or own MySQL database 
 
-In the same path, create a new directory `config` and put `application.properties.EXAMPLE` inside. Now, delete 
-the extension .EXAMPLE, leaving you with `application.properties`. In this file, configure all the necessary properties.
+### Installing SteamCMD
+Follow [this guide](https://developer.valvesoftware.com/wiki/SteamCMD#Downloading_SteamCMD) to install SteamCMD on your 
+server. After the installation is finished, set the full path to SteamCMD executable in `application.properties`. On Linux,
+the default path when installing with package manager is `/usr/games/steamcmd`.
 
-Launch the application: `java -jar arma3-server-gui.jar`. Your GUI should now be available to access from the browser
-on the set port, `8080` by default.
- 
-## Steam Workshop
-For downloading workshop mods and keeping the server up-to-date, you're going to need a Steam account with 
-a copy of Arma 3, otherwise, these features will not be available.
+### Getting SteamAuth token
+If you have Steam Guard 2FA enabled on your Steam account, you're going to need to get a SteamAuth token. To do this,
+manually launch SteamCMD with a command line. 
 
-It's not necessary to have a separate account for downloading the mods and gaming. However, you might encounter some 
-issues such as being disconnected from your Steam account when it's needed for mod download and updating.
+Type `login <your_steam_name>` and input password when prompted. Then you'll be prompted to input Steam token 
+which will be sent into your email. Enter it to successfully login and then type `quit` to exit the SteamCMD interface.
+**Keep the token for later use**.  
 
-If your account is protected by Steam Guard 2FA, you can optionally put in the verification token. This token should
-be delivered to your account's email after the first attempt of updating the server and/or downloading a mod.
+### Configuring the Admin UI app
+There is a `config` directory bundled with the .jar executable file. In it, you will find `application.properties.EXAMPLE`
+file which contains sample configuration. Copy this file and name it `application.properties`.
+
+Open the new file and set all the required properties as described.
+
+### Setting up MySQL database with Docker (preferred)
+In the project you can find `docker-compose.yml` file for the MySQL database Docker container. Edit the environment
+variables to match `application.properties` and then start the container with `docker-compose up -d`.
+
+You can also use your own MySQL database server insted if you prefer do to so.
+
+### Running the Admin UI app
+Launch the application by running: `java -jar arma3-server-gui.jar`. You should be able to access the GUI through 
+`http://localhost:8080` by default.
+
+### Setting up SteamAuth
+In the GUI, navigate to "App config" tab. Here you need to enter your Steam account username, password and
+the token which you previously received through e-mail. This is needed to interact with SteamCMD to
+install/update the server and any workshop mods.
+
+### Installing Arma 3 server
+#### Automatically (preferred)
+After setting up the SteamAuth, navigate to "Dashboard" tab and just click the "Update" button. The server should
+automatically start installing into the directory specified in the config. Once the server is installed, you
+can continue to use the GUI.
+
+#### Manually
+You can follow [this guide](https://community.bistudio.com/wiki/Arma_3_Dedicated_Server). Install the server to the
+directory specified with `serverDir` property in `application.properties`
