Well first what are your device are and then Download the one that suits your device such as Android, Linux or Windows, each file has a different installation method, if you download the Android file then you will find an APK file,and you can install it directly if you are on an Android device, then if you download the file for a Windows device then you need to open the file, look for the file with the back format .exe in and press run for Linux I don't really understand so, sorry
