+## A Note on Security
+
+99.99% of the time, you should use the prefix '$ENV.<Some_Variable_Name>' to access the environment variables. This keeps your secrets out of the metadata of the output.
+
+**IF YOU DO NOT ADD THE --disable-metadata FLAG TO COMFYUI, THIS _WILL_ SPILL SECRETS IN THE METADATA OF THE OUTPUT.**
+**You must ensure that the metadata is not attached to _any_ outputs, as some nodes will not respect the --disable-metadata flag and will attach their own metadata.**
+
+This package is designed to be used in a secure environment. It is not recommended to use this package in a public environment.
+Make sure to add the --disable-metadata flag to your comfyui command, to prevent the metadata from being attached outputs -- but be aware that some nodes will not respect this flag and will attach their own metadata.
+
+In the event that you need to use the metadata, you absolutely must use the prefix '$ENV.<Some_Variable_Name>' in any fields you want to keep secret.
+
+
+## Installation
+
+1. Download the package from the ComfyUI extensions tab.
+2. Install the package.
+3. Add the Secure API Call node to your ComfyUI workflow.
+4. Configure the node with the URL, API key, and any other necessary parameters.
+5. Run the workflow and check the output (especially the metadata, it should be empty).
