 ## First Steps
 
-To create an app project, use the command **cargo**:
+- Create a new project (named, for example - `vara-app`) by running:
 
-```bash
-cargo new gear-app --lib
-```
+    ```bash
+    cargo sails new-program vara-app
+    ```
 
-The project structure will be as follows:
+  Your `vara-app` directory tree should look like this
 
-```
-  └── gear-app // Program directory
+      ```
+      vara-app
       │
-      ├── src // Source files of the program
-      │    ├── maybe_some_file.rs // Additional module if needed
-      │    └── lib.rs // Main file of the program
+      ├── app
+      │   └── src
+      │       └── lib.rs
       │
-      └── Cargo.toml // Manifest of the program
-```
+      ├── client
+      │   └── ...
+      │
+      ├── src
+      │   └── lib.rs     
+      │
+      ├── tests
+      │   └── gtest.rs
+      │
+      ├── build.rs
+      │
+      ├── Cargo.toml
+      │
+      └──  README.md
+      ```
 
-Create a file `build.rs` with the following code:
 
-```rust
-fn main() {
-    gear_wasm_builder::build();
-}
-```
+  `Cargo.toml` file is a project manifest in Rust. The essential libraries required for compiling a project are automatically included there.
 
-`Cargo.toml` is a project manifest in Rust, containing all metadata necessary for compiling the project.
-Configure the `Cargo.toml` similarly to how it is configured in [dapp-template/Cargo.toml](https://github.com/gear-foundation/dapp-template/blob/master/Cargo.toml). Refer to [Getting Started](/docs/getting-started-in-5-minutes.md) for additional details.
+- Write your program's code
 
-## Building Rust Program
+- Compile the Wasm program in the app folder:
 
-Compile the program in the app folder:
+    ```bash
+    cargo build --release
+    ```
 
-```bash
-cargo build --release
-```
+Refer to [Getting Started](/docs/getting-started-in-5-minutes.md) for additional details.
 
-The application should compile successfully, and the final file `target/wasm32-unknown-unknown/release/gear-app.wasm` should appear.
