+## Dependency management
+
+Your created plugin will contain a oneware-extension.json. There you can specify the compatible and required dependencies.
+For an empty plugin with basic dependencies it will look similar to this:
+
+```json
+{
+  "Dependencies": [
+    {
+      "Name": "OneWare.Essentials",
+      "MinVersion": "0.9.0.0",
+      "MaxVersion": "0.9.0.0"
+    }
+  ]
+}
+```
+
+Inside the .csproj file of your plugin you can see the added nuget packages:
+
+Here you can see that OneWare Dependencies that are included in the IDE anyways are market with `Private="false" ExcludeAssets="runtime;Native"`, so ensure that these dependencies are not copied to the plugin archive. They still need to be added to make compilation work.
+
+```xml
+...
+ <ItemGroup>
+    <PackageReference Include="OneWare.Essentials" Version="0.9.0" Private="false" ExcludeAssets="runtime;Native" />
+    <PackageReference Include="OneWare.Settings" Version="0.30.3" Private="false" ExcludeAssets="runtime;Native" />
+    <PackageReference Include="OxyPlot.Avalonia" Version="2.1.0-Avalonia11" />
+    <PackageReference Include="SkiaImageView.Avalonia11" Version="1.5.0" />
+ </ItemGroup>
+...
+```
