 # Tauri + Angular
 
-This template should help get you started developing with Tauri and Angular.
+On Windows, Tauri requires the the msvc toolchain:
+```
+rustup default stable-msvc
+```
 
 ## Recommended IDE Setup
 
 [VS Code](https://code.visualstudio.com/) + [Tauri](https://marketplace.visualstudio.com/items?itemName=tauri-apps.tauri-vscode) + [rust-analyzer](https://marketplace.visualstudio.com/items?itemName=rust-lang.rust-analyzer) + [Angular Language Service](https://marketplace.visualstudio.com/items?itemName=Angular.ng-template).
+
+## Keyboard Emulation
+Keyboard emulation on most systems requires workarounds for two issues:
+- keeping the window with the keyboard on top while another (the input target) is in focus
+- not receiving focus when clicked
+- sending input
+
+## Logging and Statistics
+For logging, either use [TextTestExe](https://depts.washington.edu/acelab/proj/texttest/) (local program) or [TextTestPP](https://drustz.com/TextTestPP/) (online).
+The theoretical framework is inspired by https://www.yorku.ca/mack/bit95.html.
