 This repository holds the code necessary to develop the NZSL Dictionary App for Android. This codebase can be imported into Android Studio and you are invited to fork it to add features and bug fixes.
 
-The original code was developed by [Greg Hewgill](http://hewgill.com/) and generously gifted to the [Deaf Studies Research Unit](http://www.victoria.ac.nz/lals/centres-and-institutes/dsru) of [Victoria University of Wellignton](http://www.victoria.ac.nz/). It is maintained by [Ackama](https://www.ackama.com/).

+# Dictionary data
+
+The dictionary is updated monthly, with data released publicly at https://github.com/ODNZSL/nzsl-dictionary-scripts/releases.
+
+While we keep a version of the dictionary database up-to-date in this repository, you
+can download the latest version at any time by placing the "nzsl.dat" file in `app/src/main/assets/db/nzsl.dat`.
 
 # Missing images?
 
-This repository does not include images for the database of signs. We have created [an importer script](https://github.com/ODNZSL/nzsl-dictionary-scripts) that will fetch the latest images from the VUW servers and place them in the correct folder. You should run this once when you start development. Signs are updated every few months.
+This repository does not include images for the database of signs. Just like the dictionary data, we prepare a public export of published sign data monthly, including preprocessed images for use in the native Android and iOS apps.
+
+Find the latest release at https://github.com/ODNZSL/nzsl-dictionary-scripts/release, from which you can download `assets.tar.gz`, and place the extracted 'assets' folder at `app/src/main/assets/images/signs`.
+
+e.g.
+
+```
+tar -xf assets.tar.gz
+rm -r app/src/main/assets/images/signs
+mv assets app/src/main/assets/images/signs
+```
