# PowerShell Module Template

How to create a new PowerShell-Module with PSModuleTemplate?

1. Create a new project in Git and clone it to your computer
2. git clone
3. Copy the content from PSModuleTemplate into your new project
4. Update the README.md with your information
5. Save your function-files in the folder Code
6. Build your Module with Build-Module.ps1

## README

Information about your project.

## CHANGELOG

The Build-Module.ps1 update this file with your last change description.

## CI

This is the folder for all Continous Integration scripts like a script to automate the Module-File (Build-Module.ps1) and other scripts.

### Build-Module.ps1

This script builds your module automatically.

Build-Module.ps1 running the Functions.Tests.ps1, if no errors occured it delete the existent Module-File (PSM1) and create a new Module-File (PSM1) with all of your functions.
The script also updates the Manifest-File (PSD1) with the functions to export. If the Manifest-File doesn't exists, it will be created.

Finally Build-Module.ps1 tests if your Module can be imported and removed without any errors. It tests also if the Module contains all of your exported functions.

#### Usage

Open the Terminal and navigate to the Git-Project. Start the Build-Module.ps1 and enter the answers:

````PowerShell
./CI/Build-Module.ps1
`````
