 ### QUICKSTART
-- Download the APK for the most current release [here](https://github.com/monerujo-io/aeonwallet/releases) and install it
+- 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://aeon.monerujo.io/fdroid/repo with fingerpint ```F8 20 2E E7 A8 D0 2D 07 AF B1 3D 5A 14 F2 9F 39 04 8C 4D 2D B3 87 76 11 03 5E F9 EA 20 6A 55 5D``` 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 ```aeonwallet``` (created first time App is started)
+- Advanced users can copy over synced wallet files (all files) onto sdcard in directory Monerujo (created first time App is started)

 ## 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.
 
 ### Disclaimer
-You may lose all your AEON if you use this App.
+You may lose all your Moneroj if you use this App. Be cautious when spending on the mainnet.
 
 ### Random Notes
-- Based off aeon v0.12.0
+- Based off monero v0.11.1.0
-- works on the stagenet & mainnet
+- currently only android32 (runs on 64-bit as well)
+- works on the testnet & mainnet
+- sync is slow due to 32-bit architecture
 - use your own daemon - it's easy
 - screen stays on until first sync is complete
+- Monerujo means "Monero Wallet" according to https://www.reddit.com/r/Monero/comments/3exy7t/esperanto_corner/
 
 ### TODO
 - see taiga.getmonero.org & issues on github
@@ -26,14 +36,23 @@ You may lose all your AEON if you use this App.
 ### 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 "aeonwallet" folder periodically.
+- 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
-of the "real" stagenet.  After creating a new wallet, make a **new** one by recovering from the seed.

 ### HOW TO BUILD
-Check out [the instructions](doc/BUILDING-external-libs.md)
+No need to build. Binaries are included:
+
+- openssl-1.0.2l
+- monero-v0.12
+- boost_1_58_0
+
+If you want to build them yourself (recommended) check out [the instructions](doc/BUILDING-external-libs.md)
+
+Then, fire up Android Studio and build the APK.
