+# Soroban Project
+
+## Project Structure
+
+This repository uses the recommended structure for a Soroban project:
+```text
+.
+├── contracts
+│   └── hello_world
+│       ├── src
+│       │   ├── lib.rs
+│       │   └── test.rs
+│       └── Cargo.toml
+├── Cargo.toml
+└── README.md
+```
+
+- New Soroban contracts can be put in `contracts`, each in their own directory. There is already a `hello_world` contract in there to get you started.
+- If you initialized this project with any other example contracts via `--with-example`, those contracts will be in the `contracts` directory as well.
+- Contracts should have their own `Cargo.toml` files that rely on the top-level `Cargo.toml` workspace for their dependencies.
+- Frontend libraries can be added to the top-level directory as well. If you initialized this project with a frontend template via `--frontend-template` you will have those files already included.

+# Soroban Project
+
+## Project Structure
+
+This repository uses the recommended structure for a Soroban project:
+```text
+.
+├── contracts
+│   └── hello_world
+│       ├── src
+│       │   ├── lib.rs
+│       │   └── test.rs
+│       └── Cargo.toml
+├── Cargo.toml
+└── README.md
+```
+
+- New Soroban contracts can be put in `contracts`, each in their own directory. There is already a `hello_world` contract in there to get you started.
+- If you initialized this project with any other example contracts via `--with-example`, those contracts will be in the `contracts` directory as well.
+- Contracts should have their own `Cargo.toml` files that rely on the top-level `Cargo.toml` workspace for their dependencies.
+- Frontend libraries can be added to the top-level directory as well. If you initialized this project with a frontend template via `--frontend-template` you will have those files already included.

+# Soroban Project
+
+## Project Structure
+
+This repository uses the recommended structure for a Soroban project:
+```text
+.
+├── contracts
+│   └── hello_world
+│       ├── src
+│       │   ├── lib.rs
+│       │   └── test.rs
+│       └── Cargo.toml
+├── Cargo.toml
+└── README.md
+```
+
+- New Soroban contracts can be put in `contracts`, each in their own directory. There is already a `hello_world` contract in there to get you started.
+- If you initialized this project with any other example contracts via `--with-example`, those contracts will be in the `contracts` directory as well.
+- Contracts should have their own `Cargo.toml` files that rely on the top-level `Cargo.toml` workspace for their dependencies.
+- Frontend libraries can be added to the top-level directory as well. If you initialized this project with a frontend template via `--frontend-template` you will have those files already included.
