+# Catalyst Signed Documents importer scripts
+
+> A collection of scripts for inserting ["Catalyst Signed Documents"]
+like `Proposal`, `Comment`, `Proposal Form Template`, etc. via the `v1/document` PUT endpoint.
+
+## Setup fund
+
+The tool will find the endpoint, and any other configuration
+it needs to operate from the corresponding `settings.json` file to the provided `<env>`.
+
+```sh
+uv run setup_fund.py <env>
+```
+
+You will need to ensure that the `MK_SIGNED_DOC_PATH` environment variable is set to the correct path to the
+[`mk_signed_doc` cli tool](https://github.com/input-output-hk/catalyst-libs/tree/main/rust/signed_doc/bins)
+and also that it is set environment variable from the `settings.json` `admin_private_key_env` property.
