### [Read this on the main serverless docs site](https://www.serverless.com/framework/docs/providers/aws/examples/hello-world/fsharp/) # Hello World F# Example Make sure `serverless` is installed. [See installation guide](../../../guide/installation). Once installed the Serverless CLI can be called with `serverless` or the shorthand `sls` command. ``` $ sls Commands * You can run commands with "serverless" or the shortcut "sls" * Pass "--verbose" to this command to get in-depth plugin info * Pass "--no-color" to disable CLI colors * Pass "--help" after any for contextual help ``` ## 1. Create a service ``` sls create --template aws-fsharp --path myService ``` Using the `create` command we can specify one of the available [templates](https://serverless.com/framework/docs/providers/aws/cli-reference/create#available-templates). For this example use aws-fsharp with the `--template` or shorthand `-t` flag. The `--path` or shorthand `-p` is the location to be created with the template service files. Change directories into this new folder. ## 2. Build using .NET Core 2.X CLI tools and create zip package ``` # Linux or Mac OS ./build.sh ``` ``` # Windows PowerShell ./build.cmd ``` ## 3. Deploy ``` sls deploy ``` This will deploy your function to AWS Lambda based on the settings in `serverless.yml`. ## 4. Invoke deployed function ``` sls invoke -f hello ``` Invoke deployed function with command `invoke` and `--function` or shorthand `-f`. In your terminal window you should see the response from AWS Lambda. ```bash { "Message": "Go Serverless v1.0! Your function executed successfully!", "Request": { "Key1": null, "Key2": null, "Key3": null } } ``` Congrats you have deployed and ran your Hello World function!
