+# # Generates the 3 metadata files in `/artifacts` and the polkadot.rs file for integration tests
+#
+# This script is to be run from the root of the repository: `scripts/artifacts.sh`
+#
+# It expects a local polkadot node to be running a JSON-RPC HTTP server at 127.0.0.1:9933
+# A local polkadot node can be run via:
+# ```
+# git clone https://github.com/paritytech/polkadot.git
+# cd polkadot 
+# cargo build --release
+# ./target/release/polkadot --dev --tmp
+# ```
+
+# get the full metadata
+cargo run --bin subxt metadata > artifacts/polkadot_metadata_full.scale
+# use it to generate polkadot.rs
+cargo run --bin subxt codegen --file artifacts/polkadot_metadata_full.scale | rustfmt > testing/integration-tests/src/codegen/polkadot.rs
+# generate a metadata file that only contains the pallets Balances, Staking, System and Multisig
+cargo run --bin subxt metadata --file artifacts/polkadot_metadata_full.scale --pallets "Balances,Staking,System,Multisig" > artifacts/polkadot_metadata_small.scale
+# generate a metadata file that only contains no pallets
+cargo run --bin subxt metadata --file artifacts/polkadot_metadata_full.scale --pallets "" > artifacts/polkadot_metadata_tiny.scale
