 ## Project Setup
 
+### Install dependencies
+
 Before running or building the app, update the dependencies for the desired flavor:
 ```
-# scripts/apply_flavor_play.sh
+scripts/apply_flavor_play.sh
 ```
 
 To build the project, create a file named `<app dir>/android/key.properties`. It should contain a reference to a keystore for app signing, and other necessary credentials. See [key_template.properties](https://github.com/deckerst/aves/blob/develop/android/key_template.properties) for the expected keys.

 ```
-# ./flutterw run -t lib/main_play.dart --flavor play

+### To build the app:
+
+creare file con le tue credenziali file.keystore
+
+dove YOUR_ALIAS_NAME è il tuo unico alias name
+
+e YOUR_ALIAS_PWD è la password del tuo alias
+```sh
+keytool -genkey -v -keystore file.keystore -alias YOUR_ALIAS_NAME -storepass YOUR_ALIAS_PWD -keypass YOUR_ALIAS_PWD -keyalg RSA -validity 36500

+in questo caso ho inserito
+```sh
+cd android
+keytool -genkey -v -keystore file.keystore -alias FabioMich66 -storepass Master66 -keypass Master66 -keyalg RSA -validity 36500
+```
+se non puoi eseguire keytool perchè non è nel path di sistema cercalo usando
+```sh
+cd /
+sudo find -name keytool
+```
+compilare il file `<app dir>/android/key.properties`
+```
+nano android/key.properties
+```
+questi i miei dati utilizzando il format key_template.properties
+```
+storeFile=/Users/fabio/flutter_apps/aves/android/file.keystore
+storePassword=Master66
+keyAlias=FabioMich66
