-## First startup
+## First startup and onboarding
 
 When you first start ES-DE you will be greeted by a welcome screen, this is part of the _configurator_, the ES-DE onboarding interface. The configurator is easy to use and will guide you through the necessary setup steps.
 
 As a first step you need to give ES-DE the required storage access permission or it will not be able to function. Just enable the setting and the configurator will proceed to the next step. Next you will need to define a application data directory where your settings, scraped media, custom collections and so on will be stored. By default this will be placed in the _ES-DE_ directory in the root of your device's internal storage, and this directory will be created for you automatically.
 
-After this step you need to select a ROMs directory where your game files will be stored, by default this will be named _ROMs_ and will be located in the root of you device's internal storage. You can however choose to place this on an SD card if you want to, just change the path using the Android file selector GUI. If you do change the path to the SD card you will however need to manually create the ROMs directory as well as to delete the empty directory that was created for you on the built-in storage.

If you do change the path to the SD card you will however need to manually create the ROMs directory as well as to delete the empty directory that was created for you in the built-in storage.
 
 The next step is optional, and it's whether to create the game systems directory structure inside your ROMs folder. Performing this will also create _systeminfo.txt_ files in each system directory. These files contain information about the system such as what file extensions and emulators that are supported. They are not mandatory for the app to function, they are only there for your convenience. In general it's recommended to create the system directories, although you could remove the ones you don't need afterwards for a slightly faster app startup speed.
 
-This is basically the onboarding process, and ES-DE should now start up. Just be aware that you need to place at least one game with a supported file extension in the ROMs directory tree or ES-DE will only shown an information dialog about missing games.

 Also note that ES-DE does not install any emulators, you need to install those separately. There is more information about that topic later in this document.
 
-If you need to re-run the configurator for some reason then the easiest way is to go into the Android Apps setting screen and revoke the storage access permissions under _Special app access_. This will make the configurator run automatically next time you start ES-DE. Another way to force it to start is to clear the app's storage under _Storage & cache_ but this is normally not recommended as it also deletes all the themes you have downloaded using the theme downloader. A third option would be to rename either the ES-DE or ROMs directory as this will also trigger the configurator on next app startup.

 If you accidentally disable the touch overlay you can force the configurator to run as explained in the previous section above, this will always reset the touch overlay setting. Another option would of course be to temporarily plug in a controller or keyboard to enable the setting via its menu entry. A third option would be to manually edit the es_settings.xml file in the ES-DE application data directory. The setting you are after is named _InputTouchOverlay_ which should be changed from _false_ to _true_.
 
-Apart from this there are numerous options for the touch overlay, like the ability to change its size, opacity and fade-out time. Setting the fade-out to zero will make it permanently visible.
