 ### Files
 * `kto.crt` is our current only root certificate
+* `advancedsettings.xml` is a Kodi user configuration file
 #### Installation
-* `install.sh` copies the certificates to the right location and then reloads the system's certificates

+* go to Firefox Settings -> Privacy & Security -> Security -> Security Devices
-sudo mv /usr/lib/firefox/libnssckbi.so /usr/lib/firefox/libnssckbi.so.bak

+### Manually import in Kodi
-* Stil unclear: Will this be overwritten at Firefox update?
+In systems where we cannot import our certificate (LibreELEC, Android (TV)), we need to copy `advancedsettings.xml` and
+`kto.crt` (renamed to `cacert.pem`) to `$HOME_OF_KODI_USER/.kodi/userdata/`.
+
+This prevents KODI from using system CA, and thus to access "normal" HTTPS resources. The solution is to concatenate in
+`cacert.pem` KODI's "system" cacert and our own CA. The install script does it for LibreELEC, but not for Android (TV).
+
+#### Android (TV)
+1. find Kodi app user data directory (usually `/sdcard/Android/data/org.xbmc.kodi`)
+2. copy `advancedsettings.xml` and `kto.crt` (renamed to `cacert.pem`) to `$KODI/files/.kodi/userdata/`
+
+### Import in Windows
+1. Download the CA
+2. Double-click on it
+3. On the Certificate dialog box, click Install Certificate to start the Certificate Import Wizard
+4. On the Welcome page, click Next
+5. On the Certificate Store page, select Place all certificates in the following store and click Browse
+6. In the Select Certificate Store dialog box, select Show Physical Stores
+7. Double-click Trusted Root Certification Authorities, select Local Computer, and then click OK
+8. On the Certificate Store page, click Next
+9. On the summary page, review the details and click Finish
