Can't Find Current Documentation|OPC UA Implementation: Stacks, Tools, and Samples|Forum|OPC Foundation

I want to write an OPC UA Server, I've cloned the UA-.NETStandard repository from GitHub at this URL, but the only documentation I can find was last updated in 2015. It is also located on Github at this URL. The documentation has been helpful, but I keep finding inconsistencies between it and the contents of the repo, such as the examples listed below. Is there more recent documentation available? 

Example 1) While stepping through the tutorial on how to modify the Reference Server (located in the documentation at "Development" > "Server" > "Step 2 - address space") I was instructed to "go to line #135 [of the file UA-.NETStandard\SampleApplications\Workshop\Reference\Server\ReferenceNodeManager.cs] which should be an empty line just above 'FolderState folder1 = ' and create a new folder definition." However, that line is not blank and is not located near a line of code that mentions folder1. 

Example 2) In the documentation at "Securing Applications" > "Trusting Applications built with .NET API" it says to "launch the configuration tool" which it claims is located at "<source root>\Bin\Debug\Opc.Ua.ConfigurationTool.exe", but it is not there, and I can't find it anywhere in the repo.
