 ### QUICKSTART
 - Download APK (Release) and install it
-- Copy over synced wallet (all three files) onto sdcard in directory Monerujo (created first time app is started)
+- Run the App and select "Generate Wallet" to create a new wallet or recover a wallet
-- Start app (again)
+- Advanced users could copy over synced wallet files (all files) onto sdcard in directory Monerujo (created first time App is started)
 - see the [FAQ](doc/FAQ.md)
 
 ### Disclaimer
-This is my first serious Android App.
+You may loose all your Moneroj if you use this App. Be cautious when spending on mainnet.
 
-### Notes
+### Random Notes
-- Monerujo means "Monero Wallet" according to https://www.reddit.com/r/Monero/comments/3exy7t/esperanto_corner/
+- Based off monero v0.10.3.1 with pull requests #2238, #2239 and #2289 applied => so can be used in mainnet!
-- Special thanks to /u/gkruja for inspiration to pick this project up again
+- currently only android32 (runs on 64-bit as well)
-- Based off monero v0.10.3.1 with pull requests #2238 & #2239 applied => so can be used in mainnet!
+- works in testnet & mainnet
-- currently only android32
+- takes forever to sync due to 32-bit architecture
-- sorry for my messups in github
-- this is more of a proof of concept
-- currently only  use is checking incoming/outgoing transactions
-- works in testnet & mainnet (please use your own daemons)
-- takes forever to sync on mainnet (even with own daemon)
 - use your own daemon - it's easy
 - screen stays on until first sync is complete
+- saves wallet only on first sync and when sending transactions or editing notes
+- Monerujo means "Monero Wallet" according to https://www.reddit.com/r/Monero/comments/3exy7t/esperanto_corner/
 
 ### TODO
-- don't have the screen on for first sync - use IntentService with WakeLock instead?
+- wallet backup functions
-- make it pretty
+- review visibility of methods/classes
-- show current block height - is that relevant?
+- more sensible error dialogs
-- License Dialog
+- check licenses of included libraries; License Dialog
-- support for right-to-left layouts
-- visibility of methods/classes
-- adjust layout so we can use bigger font sizes
-- sensible error dialogs (e.g. when no write permissions granted) instead of just crashing on purpose
-- sensible loading/saving progress bars instead of just freezing up
-- spend monero - not so difficult with wallet api
-- figure out how to make it all flow better (loading/saving takes forever and does not run in background)
-- currently loading in background thread produces segfaults in JNI
-- check licenses of included libraries
 
 ### Issues
-- occasional crashes ...
+- Pending incoming transactions disappear after reload (and appear after being mined)
 
 ### HOW TO BUILD
 No need to build. Binaries are included:
 
 - openssl-1.0.2l
-- monero-v0.10.3.1 + pull requests #2238 & #2239
+- monero-v0.10.3.1 + pull requests #2238, #2239 and #2289
 - boost_1_64_0
 
-If you want to build - fire up Android Studio and build. Also you can rebuild all of the above.
+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.
