-## 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.
+## Translation
+If you'd like to help translate Monerujo, take a look at our [Weblate project!](https://hosted.weblate.org/engage/monerujo/)

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

 ### Random Notes
- works on the mainnet & stagenet
- use your own daemon - it's easy
+- Works on the mainnet & stagenet

+- See taiga.getmonero.org & issues on github

 ### 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.
+  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
-of the "real" testnet.  After creating a new wallet, make a **new** one by recovering from the seed.
-The official monero client shows the same behaviour.
