+## Nuget
+
+This library is available on Nuget:
+
+```
+<PackageReference Include="ProtobufZeroSharp" Version="0.5.0" />
+```
+
+This is a Release-mode library with commented out safety checks, so that it is faster, but also potential misusage (i.e. ReadMessage when the current tag is a varint) may lead to segmentation faults. Include `ProtobufZeroSharp.Debug` package for additional safety checks.
+
+```
+<PackageReference Include="ProtobufZeroSharp.Debug" Version="0.5.0" />
+```
+
+You can also include those packages depending on your configuration:
+
+```
+  <ItemGroup Condition="'$(Configuration)' == 'Debug'">
+    <PackageReference Include="ProtobufZeroSharp.Debug" Version="0.5.0" />
+  </ItemGroup>
+
+  <ItemGroup Condition="'$(Configuration)' != 'Debug'">
+    <PackageReference Include="ProtobufZeroSharp" Version="0.5.0" />
+  </ItemGroup>
+```
+
+For the source generator, include 
+```
+<PackageReference Include="ProtobufZero.Generator" Version="0.5.0.1" />
+```
+
+And add your .proto files to the project as AdditionalFiles.
+```xml
+<ItemGroup>
+    <AdditionalFiles Include="structures.proto" />
+</ItemGroup>
+```
