 ### QUICKSTART
 - Download the APK for the most current release [here](https://github.com/m2049r/xmrwallet/releases) and install it
+- Alternatively add our F-Droid repo https://f-droid.monerujo.io/fdroid/repo with fingerpint ```A8 2C 68 E1 4A F0 AA 6A 2E C2 0E 6B 27 2E FF 25 E5 A0 38 F3 F6 58 84 31 6E 0F 5E 0D 91 E7 B7 13``` to your F-Droid client
 - Run the App and select "Generate Wallet" to create a new wallet or recover a wallet
 - Advanced users can copy over synced wallet files (all files) onto sdcard in directory Monerujo (created first time App is started)
 - See the [FAQ](doc/FAQ.md)
 
+## Translations
+Help us translate Monerujo! You can find instructions [On Taiga](https://taiga.getmonero.org/project/erciccione-monero-localization/wiki/monerujo), and if you need help/support, open an issue or contact the Localization Workgroup. You can find us on the freenode channel `#monero-translations`, also relayed on [MatterMost](https://mattermost.getmonero.org/monero/channels/monero-translations), and matrix/riot.

 ### Issues / Pitfalls
+- Users of Zenfone MAX & Zenfone 2 Laser (possibly others) **MUST** use the armeabi-v7a APK as the arm64-v8a build uses hardware AES
+functionality these models don't have.
 - You should backup your wallet files in the "monerujo" folder periodically.
 - Also note, that on some devices the backups will only be visible on a PC over USB after a reboot of the device (it's an Android bug/feature)
 - Created wallets on a private testnet are unusable because the restore height is set to that
@@ -33,8 +46,8 @@ The official monero client shows the same behaviour.
 No need to build. Binaries are included:
