+
+  .PARAMETER ignoreLinksFile
+  Specifies the file that contains a set of links to ignore when verifying.
+
+  .PARAMETER devOpsLogging
+  Switch that will enable devops specific logging for warnings  
+
+  .PARAMETER recursive
+  Check the links recurisvely based on recursivePattern.  
+  
+  .PARAMETER baseUrl
+  Recursively check links for all links verified that begin with this baseUrl, defaults to the folder the url is contained in.

+  .PARAMETER rootUrl
+  Path to the root of the site for resolving rooted relative links, defaults to host root for http and file directory for local files.  
+  
+  .PARAMETER errorStatusCodes
+  List of http status codes that count as broken links. Defaults to 400, 401, 404, SocketError.HostNotFound = 11001, SocketError.NoData = 11004.  
+  
+  .PARAMETER branchReplaceRegex
+  Regex to check if the link needs to be replaced. E.g. ^(https://github.com/.*/(?:blob|tree)/)master(/.*)$
+  
+  .PARAMETER branchReplacementName
+  The substitute branch name or SHA commit.

+  
+  .PARAMETER userAgent
+  UserAgent to be configured for web requests. Defaults to current Chrome version.
