 ## Goals
 
 We don't want to reinvent libgit2sharp, we just want a simple query interface specific to commit messages. We don't care about diffs, code content, or even the change sets.

+For this reason, Gitbase was found to be entirely overkill even though it is pretty rad. It is a fantastic tool and I do make use of it but managing it is kind of a pain. For this reason, the
 overarching goal of this project is simplicity with the ability to opt-in to complexity when needed.
 
 ## Getting Started
 
 This utility should be used as a dotnet tool. See `tools/install_as_tool.ps1` for how to build and install Walrus on your system.
 
+```
+# Windows
+.\tools\install_as_tool.ps1
+
+# Not Windows
+bash tools/install_as_tool.ps1

 To query multiple roots or query from any location, you will need to setup a simple JSON config file. This can be specified as an env `WALRUS_CONFIG_FILE` or a file
 named `walrus.json` placed in your current working directory. The contents should look something like this is:
 
 ```
 {
   "DirectoryScanDepth": 3,
   "RepositoryRoots": [
-    "H:\\code",
+    "H:\\code"
   ],
   "AuthorAliases": {
-	  "illyum": [
-		  "[email protected]",
-		  "[email protected]"
-	  ]

+          "[email protected]"
+      ]
+  },
+  "IgnorePaths": [

+  ]
 }
