+# Bridges Tests for Local Polkadot <> Kusama Bridge
+
+This folder contains zombienet based integration test for both onchain and offchain bridges code.
+The tests are designed to be run manually.
+
+To start a test, you need to:
+
+- download latest [zombienet release](https://github.com/paritytech/zombienet/releases) to 
+`~/local_bridge_testing/bin/zombienet`.
+
+- build Polkadot binary by running `cargo build -p polkadot --release` command in the
+[`polkadot-sdk`](https://github.com/paritytech/polkadot-sdk) repository clone.
+
+- build Polkadot Parachain binary by running `cargo build -p polkadot-parachain-bin --release` command in the
+[`polkadot-sdk`](https://github.com/paritytech/polkadot-sdk) repository clone.
+
+- ensure that you have [`node`](https://nodejs.org/en) installed. Additionally, we'll need globally installed
+`polkadot/api-cli` package (use `yarn global add @polkadot/api-cli` to install it).
+
+- build Substrate relay by running `cargo build -p substrate-relay --release` command in the
+[`parity-bridges-common`](https://github.com/paritytech/parity-bridges-common) repository clone. Copy the binary to `~/local_bridge_testing/bin/substrate-relay`.
+
+- add the `sudo` pallet to the Polkadot and Kusama runtimes and give sudo rights to Alice. With this change build 
+the chain spec generator by running `cargo build --release -p chain-spec-generator --features fast-runtime` 
+command. Copy the binary to `~/local_bridge_testing/bin/chain-spec-generator`.
+
+- change the `POLKADOT_BINARY` and `POLKADOT_PARACHAIN_BINARY` paths (and ensure that the nearby variables
+have correct values) in the `./run-test.sh`.
+
+After that, you can run `./run-tests.sh <test_name>` command.
