+    Use this script to build your own edition of Cmder
 
-# Configs
-$sourcesPath = "..\vendor\sources.json"
-$saveTo = "..\vendor\"
-# -------
+    This script builds dependencies from current vendor/sources.json file and unpacks them.
+
+    You will need to make this script executable by setting your Powershell Execution Policy to Remote signed
+    Then unblock the script for execution with UnblockFile .\build.ps1
+.EXAMPLE
+    .\build.ps1
+
+    Executes the default build for cmder, this is equivalent to the "minimum" style package in the releases
+.EXAMPLE
+    .\build -verbose
+
+    Execute the build and see what's going on.
+.EXAMPLE
+    .\build.ps1 -SourcesPath '~/custom/vendors.json'
+
+    Build cmder with your own packages. See vendor/sources.json for the syntax you need to copy.
