+# Manifest Resource Streams
+Manifest Resource Streams allow you to include data from the files as byte arrays in your code. An example of its use is in the [ZMachine Demo](https://github.com/CosmosOS/Cosmos/blob/5973a3fae95c989dc13505184aff9a15aae9f65f/Demos/ZMachine/ZKernel/Kernel.cs#L19) 
+
+## Drawbacks
+Due to short comings in NASM there is a maximum size to the files which can be included this way.
+
+## How to use
+1. Set the file you want to use as embedded resource using the File Properties window in VS.

+2. In the code reference the file using the following format:
+```
+[ManifestResourceStream(ResourceName = “{project_name}.{filename_with_extension}”)] 
+static byte[] file;
+```
+The field _must_ be static. 
+
+3. To access the data simply read from the byte array defined.
