## The Journey Begins Now Young Novice
In this section you find the most basic stuff. It's aimed to help beginners who just got in touch with PowerShell.
All external links refer to the latest production ready PowerShell version. This is currently the version `5.1`.
### Docs
- [Official Documentation] - Microsoft recently moved all the PowerShell documentation to [docs.microsoft.com].
- [PowerShell Reference] - If you need details about a specific function or cmdlets you can find it there. The
Reference is grouped by the built in modules. You can expand each group and select the individual help page of
each function.
- [About Pages] - The docs does not only contain a reference of all the built in functions. It also contains the so
called _About_ pages. These pages explain specific concepts and language related topics. You can find them in a
separate _about_ section of the **Microsoft.PowerShell.Core** module reference. The titles always starts with
\_about\_\_ and the specific name.
- [The Monad Manifesto] - The Monad Manifesto is the original Jeffrey Snover-authored document that results in the
Windows PowerShell we know today.
[official documentation]: https://docs.microsoft.com/en-us/powershell
[docs.microsoft.com]: https://docs.microsoft.com
[powershell reference]: https://docs.microsoft.com/en-us/powershell/scripting/powershell-scripting?view=powershell-5.1
[about pages]: https://docs.microsoft.com/de-de/powershell/module/microsoft.powershell.core/about/about_aliases?view=powershell-5.1
[the monad manifesto]: https://www.gitbook.com/book/devops-collective-inc/the-monad-manifesto-annotated/details
{{< note >}}
You can also display the \_about\_ pages with a PowerShell function itself. To get a list of all about
pages just use `Get-Help about_\*`. All you need to to is pick a topic name and use the function again like this:
`Get-Help about_Functions`.

### Start using PowerShell
You can't learn PowerShell like every other language if you don't use it. So try to solve basic tasks with PowerShell.
Google around or ask questions in communities like:
- [StackOverflow] - The bes QA platform out there for finding solutions and help for specific topics or questions.
Don't post general or vague questions.
- [PowerShell.org] - A very helpful and friendly community.
[stackoverflow]: https://stackoverflow.com/questions/tagged/powershell
[powershell.org]: https://powershell.org/forums
## Acolyte
Once you got familiar with the basic concepts start discovering advanced techniques like _Functions_,
_Modules_, _Classes_, _Types_, _Extended Type System_, _PowerShell Remoting_, _Jobs_, _Package Management_.
### It's all about the style
As soon as you managed to spell `PowerShell` please respect the [PowerShell Best Practices and Style Guide](https://github.com/PoshCode/PowerShellPracticeAndStyle).
Unfortunately there is no standard like _PEP8_ in Python, but this is the most respected and active one. Trust me -
it's maintained by all the experts out there. Just read it, understand it, adopt it and use whatever you can.

**IMPORTANT:** There is nothing worse than reading an ugly piece of code. And yes, ugly code works as well but it's
impossible to read, understand, review, maintain and makes no fun!
{{< /alert >}}
### Important Modules
- [PSScriptAnalyzer] - Static code checker for PowerShell modules and scripts.
- [Pester] - Test and mock framework
- [platyPS] - Write PowerShell External Help in Markdown.
- [Plaster] - Plaster is a template-based file and project generator written in PowerShell.
- [psake] - A build automation tool.

### Tools
In this phase you should also start working with additional tools like:
- VCS (Version Control System):
- [Git-SCM](https://git-scm.com/)
- additional Editors, IDEs:
- [Visual Studio Code](https://code.visualstudio.com/)
- CI/CD Environments:
- [Github](https://github.com/)
- [Phabricator](https://www.phacility.com/phabricator/)
- [Jenkins](https://jenkins.io/)
- [AppVeyor](https://www.appveyor.com/)
- [GoCD](https://www.gocd.org/)
- Helper
- [ILSpy](http://ilspy.net/)
- Coverage Reports
- [Coveralls.io](https://coveralls.io/)
{{< note >}}
If you develop open source projects I recommend using [Github](https://github.com/) in combination with
[AppVeyor](https://www.appveyor.com/). You don't need to maintain any additional infrastructure and they are free
for public repositories. Otherwise I like working with Phabricator as _Git Server_ and project coordination.
If you take this path you definitely need a build server like Jenkins.
