-simple workday recording with a basic rest api
+simple working day time tracking with a basic rest api
+
+## endpoints
+
+| method | url | arguments | description | 
+| ------ | --- | --------- | ----------- |
+| `get` | /csv| from=DD.MM.YYYY<br>to=DD.MM.YYYY | get recordings (for specified range) as csv |
+| `get` | /json| from=DD.MM.YYYY<br>to=DD.MM.YYYY | get recordings (for specified range) as json |
+| `get` | /today |  | get aggregated recordings for today as json (if any) |
+| `get` | /overtime |  | get aggregated overtime (for specified range) |
+| `post` | /start | | start a new recording | 
+| `post` | /stop | | stop the current recording (if any) |
+
+**note:**  
+the api uses basic authentication so each request has to include an `Authorization` request header.
+
+## examples
+
+**start a new recording:**  
+curl -X POST -u username:password http://localhost:3333/start
+
+**stop the current recording:**  
+curl -X POST -u username:password http://localhost:3333/stop
+
+**get all recordings as json:**  
+curl -u username:password http://localhost:3333/json
+
+**get all recordings for january 2023 as csv:**  
+curl -u username:password http://localhost:3333/csv?from=01.01.2023&to=31.01.2023
+
+## configuration
+
+configuration is entirely done inside the file `config.yml`.  
+you can specify the location of the config file with the optional argument `--config` or `-c` when starting the server.  
+otherwise the program will try to find a config file at the following locations:
+- `$HOME/.config/worklog/config.yml`
+- `$PWD/config.yml`
