 # Developing NetDaemon 
-These instructions are for developing NetDaemon. For apps please use [the docs](https://netdaemon.xyz).
-For your convenience we provided with a docker setup with Home Assistant you can run on your development machine. 
-`tests/Docker/HA` you will find the docker-compose file. Run it outside the devcontainer. Remarkts that you should use port 8124 connecting to this instance of Home Assistant.
 
-## Use appsettings.Development.json
-Copy the "_appsettings.Development.json under `src/Service`
-
-## Setup the environment vars
-Alternative to using appsettings for development is to use environment varables for your Home Assistant instance
-
-| Environment variable | Description |
-| ------ | ------ |
-| HOMEASSISTANT__TOKEN   |  Token secret to access the HA instance  |
-| HOMEASSISTANT__HOST | The ip or hostname of HA |
-| HOMEASSISTANT__PORT | The port of home assistant (defaults to 8123 if not specified) |
-| NETDAEMON__GENERATEENTITIES | Generate entities, recommed set false unless debugging |
-| NETDAEMON__APPSOURCE | The folder/project/dll where it will find daemon. Set this to empty `""` to debug apps local. If needed to debug the dynamic source compilation, set to `/workspaces/netdaemon/Service/apps` |
-
-Use `src/Development/apps` as starting point to debug your stuff! 
+Thank you for considering contributing to NetDaemon. You will find a good starting point in the [documentation for developers](https://netdaemon.xyz/docs/developer)
 
 Good luck
