+Projekt Euler
+=============
 
-![Build Status](https://github.com/projekteuler/projekteuler/workflows/CI/badge.svg)
+[![Build Status](https://travis-ci.com/projekteuler/projekteuler.svg?branch=master)](https://travis-ci.org/projekteuler/projekteuler)
+[![Codacy Badge](https://api.codacy.com/project/badge/Grade/68921bff5347435f8fff10c1d6872568)](https://www.codacy.com/app/projekteuler/projekteuler)
 
-This is the Ruby on Rails web-app powering [projekteuler.de](https://projekteuler.de).
-It allows visitors to view and suggest German translations of the maths puzzles found on [projecteuler.net](https://projecteuler.net).
+This is a rails app for the german translation of [projecteuler.net](https://projecteuler.net).
 
-## Getting started
-
-1.  Download this repository, e.g., with `git clone`.
-2.  Make sure [NodeJS >= 18](https://nodejs.org) is installed.
-3.  Navigate inside the repository folder.
-4.  Use bundler to install all required gems.
-    $ bundle install
-5.  Setup the database:
-
-        $ bin/rails db:setup
-
-6.  Start the server:
-
-        $ bin/rails server
-
-7.  Open `http://localhost:3000` in your browser. You should see the web app up and running!
-8.  Start playing with the web app. By default, the database will contain some users and translations. The user `admin` can review translations, while the user `translator` has submitted some translations.
-    You can login as any user by clicking the Login button and entering their name. This is simply a mock OAuth login; in production mode, GitHub is used for login.
-9.  If you ever want to reset the database to the original state, run `rails db:reset`.
-
-## Contributing
-
-Do you have a suggestion for an improvement for the web app? Please create an [issue](https://github.com/projekteuler/projekteuler/issues) for it.
-
-Do you want to implement this improvement yourself? Follow these steps:
-
-1. Fork this repository on GitHub.
-2. Create a new branch for your improvement
-3. Implement your improvement, and create tests for it if applicable.
-4. Submit a pull request.
-
-## Deployment
-
-1. Make sure [NodeJS](https://nodejs.org) is installed.
-2. Set up a MySQL database.
-3. Copy all files from this repository.
-4. Make sure the Rails environment is set to `production`.
-5. Set up the following environment variables:
-   - `RAILS_MASTER_KEY`: The master key for decryption of the Rails credentials
-   - `DATABASE_NAME`: The name of the MySQL database
-   - `DATABASE_USERNAME`: The username for the MYSQL database
-   - `DATABASE_PASSWORD`: The password for the MYSQL database
-   - `DATABASE_HOST`: The host of the MYSQL database
-   - `DATABASE_PORT`: The port of the MYSQL database
-   - `GITHUB_CLIENT_ID`: The client ID of your GitHub OAuth App (that you will need to create)
-   - `GITHUB_CLIENT_SECRET`: The client secret of the GitHub OAuth App
-6. Install all required gems with `bundle install`.
-7. Load the database schema with `bin/rails db:schema:load`.
-8. Precompile all assets with `bin/rails assets:precompile`.
-9. Start the server, e.g., with `bin/rails server`.
-
-Anytime you update the files, you should run `bin/rails db:migrate`, `bin/rails log:clear tmp:clear`, `bin/rails assets:precompile` and then restart the server.
