+## LLDB Pretty-Printer Script for Smart Contracts
+
+The LLDB pretty-printer script allows you to view managed types such as `BigUint` and `ManagedBuffer` in a readable format during debugging sessions.
+
+### Prerequisites
+
+- [**Visual Studio Code**](https://code.visualstudio.com/)
+- [**CodeLLDB**](https://marketplace.visualstudio.com/items?itemName=vadimcn.vscode-lldb) (LLDB Debugger extension for Visual Studio Code)
+
+
+### Installation
+
+First, download the [**MultiversX LLDB Pretty-Printer Script**](https://github.com/multiversx/mx-sdk-rs/blob/master/tools/rust-debugger/pretty-printers/multiversx_sc_lldb_pretty_printers.py) to a known directory on your system.
+
+Then, adjust the `lldb.launch.initCommands` entry in your Visual Studio Code settings to import the pretty-printer script:
+
+
+```json
+{
+    "lldb.launch.initCommands": [
+        "command script import /path/to/pretty-printers/multiversx_sc_lldb_pretty_printers.py"
+    ]
+}
+```
+
+Once you have completed the steps above, you can start debugging your smart contract in Visual Studio Code. The pretty-printer script will automatically format managed types for you.
