 To develop smart contracts in C# on ubuntu, basically you need to do the following:
 
-      1. Create a library project, write code, and add the smart contract library.
-   2. Execute neo-compiler/neon to generate the compiler.
-      3. Run neon to generate the .avm file.

+2. Execute `neo-compiler/neon` to generate the compiler.
+3. Run `neon` to generate the .avm file.
 
 ## Create a smart contract project
 
 1. In the dotnet command line, create a library project:
 
-```
-mkdir NeoContractDemo
-cd ./NeoContractDemo/
-dotnet new library
-rm ./Class1.cs
-vim NeoContractDemo.cs
-```
+   ```c#
+   mkdir NeoContractDemo

+           return true;
+       }
+   }
+   ```
 
 3. Add the smart contract reference:
 
-    ```
-    dotnet add package Neo.SmartContract.Framework --version 2.5.4
-    ```
+   ```
+   dotnet add package Neo.SmartContract.Framework --version 2.5.4
