+### Build APK
+
+1. `npx expo-doctor` to check if everything is alright, then `npx expo prebuild` to create/update the android folder.
+2. Generate keystore file with:
+
+```
+keytool -genkey -v -keystore your_key_name.keystore -alias your_key_alias -keyalg RSA -keysize 2048 -validity 10000
+```
+
+3. Put the keystore file inside `android/app` folder.
+4. Add below inside `signingConfigs` of `android/app/build.gradle` file:
+
+```
+release {
+    storeFile file('your_key_name.keystore')
+    storePassword 'password'
+    keyAlias 'your_key_alias'
+    keyPassword 'password'
+}
+```
+
+5. Modify buildTypes → release of `android/app/build.gradle` file to:
