-# MediarepoUi
+<h1 align="center">
+mediarepo-ui
+</h1>
+<h3 align="center" style="color:red">This repository is a work in progress</h3>
 
-This project was generated with [Angular CLI](https://github.com/angular/angular-cli) version 12.2.9.
+- - -
 
-## Development server
+This repository contains a frontend client to connect to the [mediarepo-daemon](https://github.com/Trivernis/mediarepo-daemon).
+It is written in tauri (yay).
 
-Run `ng serve` for a dev server. Navigate to `http://localhost:4200/`. The app will automatically reload if you change any of the source files.
+## Usage
 
-## Code scaffolding
+Refer to [the tauri documentation](https://tauri.studio/en/docs/getting-started) for information about setting up your environment to build this project.
+With the `cargo-tauri` tooling installed you can run
+```
+cargo tauri dev
+```
+to start the application in development mode or 
+```
+cargo tauri build
+```
+to bundle the application.
 
-Run `ng generate component component-name` to generate a new component. You can also use `ng generate directive|pipe|service|class|guard|interface|enum|module`.
+## License
 
-## Build
-
-Run `ng build` to build the project. The build artifacts will be stored in the `dist/` directory.
-
-## Running unit tests
-
-Run `ng test` to execute the unit tests via [Karma](https://karma-runner.github.io).
-
-## Running end-to-end tests
-
-Run `ng e2e` to execute the end-to-end tests via a platform of your choice. To use this command, you need to first add a package that implements end-to-end testing capabilities.
-
-## Further help
-
-To get more help on the Angular CLI use `ng help` or go check out the [Angular CLI Overview and Command Reference](https://angular.io/cli) page.
