@@ -11,11 +11,11 @@ There are two modes, offline and online, each is tested differently:
 
 The online updater workflow takes a url endpoint (for early testing, this will be a file url) that points to a manifest file, a sample of which has been provided under the `tmp` directory relative to this README. The manifest file includes, amount other things specified in the updater RFC, another file URL to a gpt4all installer.
 
-The first thing testing this will require is a manual update of that file url in the mainfest xml file to point to the DMG on MacOS or exe on Windows, of an existing online Gpt4All installer, as well as a corresponding sha256 sum of the given installer. The manifest is filled with other stub info for testing, you're welcome to leave it as is or fill it out correctly for each testing iteration.

 That is all that is required for configuration. Now simply build this project via CMake, using standard CMake build practices. CMake will build the online installer by default, so no extra arguments are required.
 
-One argument is required for the online installer, the url where the updater should expect the mainfest file to be. This can be any url accessible to your system, but for simplicity and testing reasons, its usually best to use a file url.

 This is provided via the cmake command line argument `-DGPT4ALL_MANIFEST_ENDPOINT=<url>`.
 
 Now configure and build the updater with CMake.
