+This folder serves as a reference documentation for chopstick tests and the Parity-owned ecosystems.  
+It provides a working set of configuration files together with the WASM BLOBs, specifically for the Westend ecosystem.  
+For additional resources and original Acala configuration files, including documentation, refer to the [Acala repository](https://github.com/AcalaNetwork/chopsticks/tree/master/configs) or [Papermoon chopsticks overview](https://papermoonio.github.io/polkadot-ecosystem-docs-draft/dev-tools/chopsticks/overview/#using-a-configuration-file)
+
+Config files, especially `wasm-override:` fields there, assume that there is a `wasms` folder within the same parent directory, and it contains pre-built WASM BLOBs of the 
+ecosystem under tests.

+# v5-sac-test
+
+To install dependencies:
+
+```bash
+bun add polkadot-api
+# now you need to switch to another terminal window where you executed bunx command, make sure that chains are running and copy Asset Hub's port in the command below (usually the port is 8001).
+bun papi add wnd_ah -w ws://localhost:8001
+bun add @polkadot-labs/hdkd
+```
+
+To run the test:
+
+```bash
+bun test ./index.ts
+# note: the test may time out during the first run. Single retry usually helps.
+```
+
+This project was created using `bun init` in bun v1.1.34. [Bun](https://bun.sh) is a fast all-in-one JavaScript runtime.
