 # common-config
 
 This is a common configuration library for eigenservice
+
+
+
+Add this dependency to your application e.g. using poetry (ssh-add so you don't have to type the ssh-password over and over):
+
+```bash
+ ssh-add
+ poetry add git+ssh://git@code.hfbk.net:4242/id/eigenservice/common-config.git -vvv
+```
+
+When something changes update it like this:
+
+```bash
+poetry update common-config
+```
+
+
+
+Then in the application use something like this as a starting point:
+
+```python
+#!/usr/bin/env python 
+#-*- coding: utf-8 -*-
+import common_config
+from common_config import initialize_config, read_settings, main
+
+# Name of this application, used in directory names, etc
+APPLICATION_NAME = "eigenservice"
+
+# suffix added to the config files (e.g. `00-suffix.toml`)
+SUFFIX = "config"
+
+# Do not change here, just use an override instead
+DEFAULT_CONFIG = """
+[application]
+loglevel = "info"
+level = 9001
+mood = "very"
+"""
+
+# Override the global variables in the common-config.common module
+common_config.common.APPLICATION_NAME = APPLICATION_NAME
+common_config.common.SUFFIX           = SUFFIX
+common_config.common.DEFAULT_CONFIG   = DEFAULT_CONFIG
+
+
+if __name__ == "__main__":
+   main()
+```
+
+If people now run that file, they will get an interactive configuration-tool
