# Alter Installation
## Configuration File
To alter the installation you can create the file
`.nanodroid-setup`
on your device, in one of the following directories
* `/sdcard` (internal storage)
* `/external_sd` (TWRP path to SD Card (if any))
* directory containing the zip file
* `/data` (fallback)
create it manually with the following content for the **full** package
```
nanodroid_microg=1
nanodroid_gmscore=0
nanodroid_fdroid=1
nanodroid_apps=1
nanodroid_play=(1 0)
nanodroid_overlay=1
nanodroid_zelda=1
nanodroid_mapsv1=1
nanodroid_init=1
nanodroid_gsync=0
nanodroid_swipe=0
nanodroid_forcesystem=0
nanodroid_nlpbackend=(1 0 0)
nanodroid_bash=1
nanodroid_nano=1
nanodroid_utils=1
nanodroid_fonts=1
nanodroid_override=0
```
the **microG** package supports the following options (nanodroid_microg is always 1)
```
nanodroid_gmscore=0
nanodroid_play=(1 0)
nanodroid_overlay=0
nanodroid_mapsv1=1
nanodroid_gsync=0
nanodroid_swipe=0
nanodroid_forcesystem=0
nanodroid_nlpbackend=(1 0 0)
```
the **F-Droid** (nanodroid_fdroid is always 1) and **Bromite WebView** pckage supports the following options
```
nanodroid_forcesystem=0
```
where `1` means `on` and `0` means `off` . If no `.nanodroid-setup` is found, the [default settings ](.nanodroid-setup ) will be used (equals to the example above), if your `.nanodroid-setup` file exists, but is missing entries, those entries will be added, using the default values.
Alternatively you can also use the NanoDroid-SetupWizard package instead of manual creation of the configuration file.
