+## Package authenticity from GitHub
+- Download the app from [GitHub releases](https://github.com/Kunzisoft/KeePassDX/releases/latest)
+- Install [`apksigner`](https://developer.android.com/tools/apksigner) from [Android Studio](https://developer.android.com/studio)
+- Open the directory where you saved the downloaded file in the Terminal
+- Make sure that you have `apksigner` installed by running:
+```shell
+apksigner --version
+```
+- Depending on the APK file you downloaded, run:
+
+```shell
+apksigner verify --verbose --print-certs -min-sdk-version 24 KeePassDX-*.apk
+```
+
+You should get this output :
+```shell
+Verified using v2 scheme (APK Signature Scheme v2): true
+...
+Number of signers: 1
+Signer #1 certificate SHA-256 digest: 7d55b8af210381aabf960f07e17cf7857b6d2a642ca2da6bf0bdf1b200362f04

+```
+If it's the case, this means that the APK was well built by the author of KeePassDX.
