Hi! I was using PowerShell on a daily basis 3 years ago up until about 1 year ago. After that i have been using it sporadicaly. I have forgotten many things and i feel a bit “stuck”. I am looking for a short guide, some papers to refresh my memory on subjects like hashtables and arrays, objects, code blocks and scripting generally… Throw any ideas my way! 😃

Best Regards

Hey there.

[PowerShell Explained](https://powershellexplained.com/) is a good reference for learning about hashtables, arrays, objects, etc. Also, highly recommend installing the PSKoans module from the gallery, created by @ta11ow.

`Install-Module -Name PSKoans`
