 1. When prompted, select *Android Build Support* and *Windows Build Support (Mono)*.
     - You may need to install `cpio` from your distro's repos in order to install these components (The AppImage erroneously doesn't include it). To check if it's installed, run `which cpio` in a terminal.
 
+
+### Standalone Install (Pro and Plus Licenses Only)
+
+You can download the Unity editor tar file from the [official Unity archive](https://unity.com/releases/editor/archive). After downloading, extract the contents into a folder of your choice, ensuring that the folder structure remains intact.
+
+1. To activate your Unity installation, open a terminal and run the following command, replacing the placeholders with your actual license serial number and Unity account credentials:
+   ```bash
+   ./Editor/Unity -quit -batchmode -serial XX-XXXX-XXXX-XXXX-XXXX-XXXX -username 'yourUnity@mail.com' -password 'XXXXXXX'
+   ```
+
+2. To open a project in Unity, use the following command, replacing `/path/to/your/project` with the actual path to your project:
+   ```bash
+   ./Editor/Unity -projectPath /path/to/your/project
+   ```
+
+Additionally, you can manage Unity versions using the command-line tool available at [unity-version-manager](https://github.com/Larusso/unity-version-manager).

 ## ALCOM
 
 vrc-get is a native FOSS package manager written in Rust. Its GUI counterpart was formerly known as vrc-get-gui, but has been rebranded as ALCOM (***Al***ternative Creator ***Com***panion).
 
+### AppImage

 1. Download the [AppImage from the latest "gui" release\*](https://github.com/vrc-get/vrc-get/releases). Pick the file named `alcom-<some version>-x86_64.AppImage`.
     - \*Some users say the v0.16.0 and v1.0.0 releases only show a blank white GUI. If you're affected by this bug, downgrade to [v0.1.15](https://github.com/vrc-get/vrc-get/releases/tag/gui-v0.1.15) AppImage for the time being.

+### Flatpak
+
+1. To use the Flatpak version of Unity with ALCOM, create a bash script with the following content and save it as `unity-flatpak.sh`:
+   ```bash
+   #!/bin/bash
+
+   # Execute the Flatpak application with the provided arguments
+   flatpak run com.unity.UnityHub -- "$@"
+   ```
+
+2. Make the script executable by running:
+   ```bash
+   chmod +x unity-flatpak.sh
+   ```
+
+3. In ALCOM, point the Unity executable to the `unity-flatpak.sh` script you just created.
+
+4. Next, create a symlink for the Flatpak Unity configuration folder to the system's Unity configuration folder by running:
+   ```bash
+   ln -s ~/.var/app/com.unity.UnityHub/config/unity3d/Unity/licenses/ ~/.config/unity3d/Unity/licenses
+   ```
+
+### Standalone
+
+1. To use the standalone version of Unity with ALCOM, add the Unity executable for the specific editor version you have installed.
+
+2. Ensure that the Unity executable is correctly pointed to within ALCOM's settings.
+
+
+Now you should be able to create and upload avatars and worlds as you normally would.

+### Unity 2021 Crashing
+
+If you are experiencing crashes with Unity 2021.3.x on Linux, follow these steps to resolve the issue:
+
+1. Ensure you have installed the correct version of Unity along with both Windows and Linux build support.
+
+2. Navigate to the Unity editor installation directory:
+   ```bash
+   cd ~/Unity/Hub/Editor/2021.3.xxxx/Editor/Data
+   ```
+
+3. Rename the `bee_backend` file to `bee_backend.bin` by running:
+   ```bash
+   mv bee_backend bee_backend.bin
+   ```
+
+4. Create a new text file named `bee_backend` in the same directory:
+   ```bash
+   touch bee_backend
+   ```
+
+5. Make the new `bee_backend` file executable:
+   ```bash
+   chmod 755 bee_backend
+   ```
+
+6. Open the `bee_backend` file in a text editor and add the following script:
+   ```bash
+   #!/bin/bash
+
+   args=("$@")
+   for ((i=0; i<"${#args[@]}"; ++i))
+   do
+       case ${args[i]} in
+           --stdin-canary)
+               unset args[i];
+               break;;
+       esac
+   done
+   ${0}.bin "${args[@]}"
