+## VSCode
+
+To run and debug single node cluster with VSCode:
+
+1. Clone and build [frostfs-contract](https://git.frostfs.info/TrueCloudLab/frostfs-contract) repository to the same directory level as `frostfs-node`. For example:
+
+```
+/
+├── src
+    ├── frostfs-node
+    └── frostfs-contract
+```
+See `frostfs-contract`'s README.md for build instructions.
+
+2. Copy `launch.json` and `tasks.json` from `dev/.vscode-example` directory to `.vscode` directory. If you already have such files in `.vscode` directory, then merge them manually.
+
+3. Go to **Run and Debug** (`Ctrl+Shift+D`) and start `IR+Storage node` configuration.
+
+4. To create container and put object into it run (container and object IDs will be different):
+
+```
+./bin/frostfs-cli container create -r 127.0.0.1:8080 --wallet ./dev/wallet.json --policy "REP 1 IN X CBF 1 SELECT 1 FROM * AS X" --await
