 ## Limitations
 
+### Not available on Cloud or Desktop
+
 Like the Execute Command node, the PowerShell node won't work on n8n Cloud.
 
 Community nodes are currently unavailable on n8n Desktop.
 
+###
+
+## Technical background
+
+This node uses `execPromise`, an n8n function that promisifies Node.js' `child_process.exec()`. Refer to the [Node.js 16.x documentation](https://nodejs.org/docs/latest-v16.x/api/child_process.html#child_processexeccommand-options-callback) for more background.
+
+> **Note:** because we're using `exec` rather than `spawn`, there is no option to detach the child process. This means the n8n workflow waits for the PowerShell script to complete before proceeding.
+
+> **Note:** `exec` is designed to handle commands with small outputs. Be cautious about using this node for memory-heavy operations.
