+### Ignore & Mapping files
+
+`shsf remote push` supports a `.shsfignore` file (gitignore-like) placed in the source directory or repository root. Lines are treated like gitignore patterns and will prevent matching files from being pushed.
+
+You can also create a `.shsf.json` mapping file in the repository root so you don't need to pass `--id` and `--from` every time. Example `.shsf.json`:
+
+```json
+{
+	"default": {
+		"id": "my-function-id",
+		"from": "src/functions/my-fn"
+	}
+}
+```
+
+Command-line flags take precedence over values in `.shsf.json`.

 ## Instructions
 Use these commands for when you need to interact with shsf from the command line. Its faster than using the ui for almost all ops.
