## Installing /e/OS

{% include alerts/tip.html content="For Windows users, we advise to use Git Bash. For more info about Downloads and Installation see [Official Documentation](https://git-scm.com/about)"%}

1. Unzip the archive

    ```

    unzip <fileyoudownloaded>

    ```

   > Replace `<fileyoudownloaded>` with the name of the archive file you downloaded.

   > Alternately you can create a folder and unzip the archive there.

1. Confirm that extracted directory contains following content:

    - `bin-linux-x86 directory` - which contains linux tools including fastboot and adb

    - `bin-msys directory` - which contains Windows tools including fastboot and adb

    - `img files` - The `img` files that are to be flashed onto the device.

    - `flash_tetris_factory.sh` - The installer script.

1. Boot into bootloader/fastboot mode.

    - Power OFF the device.

    - Hold `Power` + `Volume Up` button combo simultaneously and then select `Fastboot` from the menu and select `Volume Up` to confirm selection.

1. Run the installer script on Terminal(Linux) or on Git Bash UI(Windows).

    - Make sure you are in the current directory which contains the `flash_tetris_factory.sh` file.

    **Linux**

    - Right click -> Open terminal here

    **Windows**

    - Right click -> Git Bash here

    - Execute the following command:

    ```

    chmod +x flash_tetris_factory.sh && ./flash_tetris_factory.sh

    ```

    The script will flash all required files and will wait for input at the last step.
