+If you like this project, please consider supporting it 🙂. You can donate either through [buying me a coffee](https://buymeacoff.ee/n1try) or becoming a GitHub sponsor. Every little donation is highly appreciated and boosts the developers' motivation to keep improving Wakapi!
 
-## Prerequisites
-### Server
+## 👀 Demo 
+🔥 **New:** There is a hosted [demo version](https://apps.muetsch.io/wakapi) available now. Go check it out! Please use responsibly.
+
+To use the demo version set `api_url = https://apps.muetsch.io/wakapi/api/heartbeat`. However, this hosted instance might be taken down again in the future, so you might potentially lose your data ❕
+
+## ⚙️ Prerequisites
+**On the server side:**
 * Go >= 1.13 (with `$GOPATH` properly set)
-* A MySQL database
+* gcc (to compile [go-sqlite3](https://github.com/mattn/go-sqlite3))
+    * Fedora / RHEL: `dnf install @development-tools`
+    * Ubuntu / Debian: `apt install build-essential`
+    * Windows: See [here](https://github.com/mattn/go-sqlite3/issues/214#issuecomment-253216476)
+* _Optional_: A MySQL- or Postgres database
 
-### Client
+**On your local machine:**
 * [WakaTime plugin](https://wakatime.com/plugins) for your editor / IDE
 
-## Usage
-* Create an empty MySQL database
-* Enable Go module support: `export GO111MODULE=on`
-* Get code: `go get github.com/n1try/wakapi`
-* Go to project root: `cd "$GOPATH/src/github.com/n1try/wakapi"`
-* Copy `.env.example` to `.env` and set database credentials
-* Set target port in `config.ini`
-* Build executable: `go build`
-* Run server: `./wakapi`
-* Edit your local `~/.wakatime.cfg` file
-  * `api_url = https://your.server:someport/api/heartbeat`
-  * `api_key = the_api_key_printed_to_the_console_after_starting_the_server`
-* Open [http://localhost:3000](http://localhost:3000) in your browser
+## ⌨️ Server Setup
+### Run from source
+1. Clone the project
+1. Copy `config.default.yml` to `config.yml` and adapt it to your needs
+1. Build executable: `GO111MODULE=on go build`
+1. Run server: `./wakapi`
+
+**As an alternative** to building from source you can also grab a pre-built [release](https://github.com/muety/wakapi/releases). Steps 2, 3 and 5 apply analogously.
+
+**Note:** By default, the application is running in dev mode. However, it is recommended to set `ENV=production` for enhanced performance and security. To still be able to log in when using production mode, you either have to run Wakapi behind a reverse proxy, that enables for HTTPS encryption (see [best practices](#best-practices)) or set `security.insecure_cookies` to `true` in `config.yml`. 
 
 ### Run with Docker
-* Edit `docker-compose.yml` file and change passwords for the DB
-* Build the container `docker-compose build`
-* Start the application `docker-compose up -d`
-* To get the api key look in the logs `docker-compose logs | grep "API key"`
-* The application should now be running on `localhost:3000`
+```
+docker run -d -p 3000:3000 --name wakapi n1try/wakapi
+```
 
+By default, SQLite is used as a database. To run Wakapi in Docker with MySQL or Postgres, see [Dockerfile](https://github.com/muety/wakapi/blob/master/Dockerfile) and [config.default.yml](https://github.com/muety/wakapi/blob/master/config.default.yml) for further options.
 
-### User Accounts
-* When starting wakapi for the first time, a default user _**admin**_ with password _**admin**_ is created. The corresponding API key is printed to the console.
-* Additional users, at the moment, can be added only via SQL statements on your database, like this:
-    * Connect to your database server: `mysql -u yourusername -p -H your.hostname` (alternatively use GUI tools like _MySQL Workbench_)
-    * Select your database: `USE yourdatabasename;`
-    * Add the new user: `INSERT INTO users (id, password, api_key) VALUES ('your_nickname', MD5('your_password'), '728f084c-85e0-41de-aa2a-b6cc871200c1');` (the latter value should be a random [UUIDv4](https://tools.ietf.org/html/rfc4122), as can be found in your `~/.wakatime.cfg`)
+## 🔧 Configuration
+You can specify configuration options either via a config file (default: `config.yml`, customziable through the `-c` argument) or via environment variables. Here is an overview of all options.

+
+## 💻 Client Setup
+Wakapi relies on the open-source [WakaTime](https://github.com/wakatime/wakatime) client tools. In order to collect statistics to Wakapi, you need to set them up.
+
+1. **Set up WakaTime** for your specific IDE or editor. Please refer to the respective [plugin guide](https://wakatime.com/plugins)
+2. Make your local WakaTime client talk to Wakapi by **editing your local `~/.wakatime.cfg`** file as follows
+
+```
+api_url = https://your.server:someport/api/heartbeat`
+api_key = the_api_key_printed_to_the_console_after_starting_the_server`
+```
+
+You can view your API Key after logging in to the web interface.
+
+## 🔵 Customization
 
 ### Aliases
 There is an option to add aliases for project names, editors, operating systems and languages. For instance, if you want to map two projects – `myapp-frontend` and `myapp-backend` – two a common project name – `myapp-web` – in your statistics, you can add project aliases.
 
-At the moment, this can only be done via raw database queries. See [_User Accounts_](#user-accounts) section above on how to do such.
-For the above example, you would need to add two aliases, like this:
+At the moment, this can only be done via raw database queries. For the above example, you would need to add two aliases, like this:
 
-* `INSERT INTO aliases (type, user_id, key, value) VALUES (0, 'your_username', 'myapp-web', 'myapp-frontend')` (analogously for `myapp-backend`)
+```sql
+INSERT INTO aliases (`type`, `user_id`, `key`, `value`) VALUES (0, 'your_username', 'myapp-web', 'myapp-frontend');
+```
 
 #### Types
 * Project ~  type **0**
 * Language ~  type **1**
 * Editor ~ type **2**
 * OS ~  type **3**
+* Machine ~  type **4**
 
-**NOTE:** In order for the aliases to take effect for non-live statistics, you would either have to wait 24 hours for the cache to be invalidated or restart Wakapi.
+## 🔧 API Endpoints
+The following API endpoints are available. A more detailed Swagger documentation is about to come ([#40](https://github.com/muety/wakapi/issues/40)).
 
-## Best Practices
+* `POST /api/heartbeat`
+* `GET /api/summary`
+  * `string` parameter `interval`: One of `today`, `day`, `week`, `month`, `year`, `any`
+* `GET /api/compat/v1/users/current/all_time_since_today` (see [Wakatime API docs](https://wakatime.com/developers#all_time_since_today))
+* `GET /api/compat/v1/users/current/summaries` (see [Wakatime API docs](https://wakatime.com/developers#summaries))
+* `GET /api/health`
+
+## ⤴️ Prometheus Export
+If you want to export your Wakapi statistics to Prometheus to view them in a Grafana dashboard or so please refer to an excellent tool called **[wakatime_exporter](https://github.com/MacroPower/wakatime_exporter)**.
+
+[![](https://github-readme-stats.vercel.app/api/pin/?username=MacroPower&repo=wakatime_exporter&show_owner=true)](https://github.com/MacroPower/wakatime_exporter)
+
+It is a standalone webserver that connects to your Wakapi instance and exposes the data as Prometheus metrics. Although originally developed to scrape data from WakaTime, it will mostly for with Wakapi as well, as the APIs are partially compatible.
+
+Simply configure the exporter with `WAKA_SCRAPE_URI` to equal `"https://wakapi.your-server.com/api/compat/wakatime/v1"` and set your API key accordingly.
+
+## 🏷 Badges
+We recently introduced support for [Shields.io](https://shields.io) badges (see above). Visit your Wakapi server's settings page to see details.
+
+## 👍 Best Practices
 It is recommended to use wakapi behind a **reverse proxy**, like [Caddy](https://caddyserver.com) or _nginx_ to enable **TLS encryption** (HTTPS).
-However, if you want to expose your wakapi instance to the public anyway, you need to set `listen = 0.0.0.0` in `config.ini`
+However, if you want to expose your wakapi instance to the public anyway, you need to set `server.listen_ipv4` to `0.0.0.0` in `config.yml`
 
-## Todo
-* User sign up and log in
-* Additional endpoints for retrieving statistics data
-* Support for SQLite database
-* Unit tests
-
-## Important Note
+## ⚠️ Important Note
 **This is not an alternative to using WakaTime.** It is just a custom, non-commercial, self-hosted application to collect coding statistics using the already existing editor plugins provided by the WakaTime community. It was created for personal use only and with the purpose of keeping the sovereignity of your own data. However, if you like the official product, **please support the authors and buy an official WakaTime subscription!**
