+# Create a function
+
+Install FaasNet template. This utility can be used to generate Function project in C#.
+
+```
+dotnet new --install FaasNet.Templates
+```
+
+Create a Function project
+
+```
+mkdir QuickStart
+cd QuickStart
+
+mkdir src
+cd src
+
+dotnet new faasnetfn -n Function
+```
+
+The following files will be created :
+
+* *Startup.cs* and *Program.cs*: the application entry point.
+* *HelloWorldConfiguration.cs*: configuration properties of the function.
+* *FunctionHandler.cs*: contains the business logic. This class has one function which accepts one parameter and returns a JSON result. The input parameter has two distinct properties :
+
+  * Configuration: its value is coming from the gateway, it will be used to configure the behavior of the function for example : `ConnectionString` and `SQL Statement`.
+  * Input: value passed by caller.
+
+In case the Visual Studio Support is needed, a solution can be created :
+
+```
+cd ..
+dotnet new sln -n QuickStart
+```
+
+Add the Function project into the solution.
+
+```
+dotnet sln add ./src/Function/Function.csproj
+```
+
+# Deploy a function
+
+> [!WARNING]
+> Before you start, Make sure your working environment is properly configured.
+
+When the Function project is ready, it can be deployed to the Gateway API.
+
+First of all, open a command prompt and execute the following command line to create a Docker file. The `DIRECTORY` variable must be replaced by the directory of the Function.csproj project.
+
+```
+FaasNet.CLI function -df <DIRECTORY>
+```
+
+Execute the following instruction to locally build the Docker image. 
+The `DIRECTORY` variable must be replaced by the directory of the Function.csproj project, and the `IMAGENAME` variable must be replaced by the name of the Docker image for example : localhost:5000/function.
+
+```
+FaasNet.CLI function -db <DIRECTORY> -t <IMAGENAME>
+```
+
+Execute the following command line to push the local Docker image into a registry. The `IMAGENAME` variable must be replaced by the name of the Docker Image.
+
+```
+FaasNet.CLI function -dp <IMAGENAME>
+```
+
+Finally, execute the latest command line to deploy the function into the Gateway API. Replace the `FUNCTIONNAME` variable by the name of your function and replace the `IMAGENAME` variable by the name of your Docker image.
+
+```
+FaasNet.CLI function deploy -name <FUNCTIONAME> -image <IMAGENAME>
+```
+
+# Execute a function
+
+> [!WARNING]
+> Before you start, Make sure you have a function deployed in the Gateway API.
+
+Execute the following command to invoke a function. Replace the `FUNCTIONNAME` variable by the name of your function.
+
+```
+FaasNet.CLI function invoke <FUNCTIONNAME> -input {} -configuration {'firstName':'coucou'}
+```
+
+The following message is displayed
+
+```
+{
+  "content": {
+    "message": "Hello 'coucou'"
+  }
+}
+```
