-# Budget
+# Twigs Web Client
 
-This project was generated with [Angular CLI](https://github.com/angular/angular-cli) version 6.1.5.
+# IMPORTANT: This repository is no longer maintained. The web version of Twigs has been replaced with a server-rendered implementation in the [backend repository](https://github.com/wbrawner/twigs)
 
-## Development server
+Twigs is an open source budgeting app aimed at people who need to share a budget. This project serves as the web front end, and is powered by Angular. The main back end project can be found at [wbrawner/twigs-server](https://github.com/wbrawner/twigs-server)
 
-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.
+## Building
 
-## Code scaffolding
+You'll need NodeJS and NPM, then run
 
-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`.
+    npm run build
 
-## Build
+If you would like to tinker with the site and have it hot reload, then run
 
-Run `ng build` to build the project. The build artifacts will be stored in the `dist/` directory. Use the `--prod` flag for a production build.
+    npm run start
 
-## Running unit tests
+The app will be available at http://localhost:4200
 
-Run `ng test` to execute the unit tests via [Karma](https://karma-runner.github.io).
+## Self-hosting
 
-## Running end-to-end tests
+Eventually the plan is to ship this web app within the JAR for the server, but for now you'll need to run them separately. Before you build the app, be sure to change the `apiUrl` value in [src/environments/environment.prod.ts](src/environments/environment.prod.ts). Then you can run the following command to get an optimized version of the build for production deployments
 
-Run `ng e2e` to execute the end-to-end tests via [Protractor](http://www.protractortest.org/).
+    npm run package
 
-## Further help
+This will output the app in a folder called `dist/twigs`, which you can then serve directly with Apache or Nginx or any static file server.
 
-To get more help on the Angular CLI use `ng help` or go check out the [Angular CLI README](https://github.com/angular/angular-cli/blob/master/README.md).
