 You may lose all your Moneroj if you use this App. Be cautious when spending on the mainnet.

 ### Random Notes
- Based off monero v0.11.1.0
- currently only android32 (runs on 64-bit as well)
- works on the testnet & mainnet
- sync is slow due to 32-bit architecture
+- works on the mainnet & stagenet
 - 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

 The official monero client shows the same behaviour.

 ### HOW TO BUILD
-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)
+See [the instructions](doc/BUILDING-external-libs.md)

 Then, fire up Android Studio and build the APK.
