-To install Git LFS, download the binary here: https://git-lfs.github.com/.
+This repository uses Git LFS for storing large binary files.  
 
-After installation, you will need to install the necessary git hooks with this command 
+Verify you have Git LFS installed by running the following command to print the version number.
 ```
-git lfs install
+git lfs --version 
 ```
 
-### Create a Git Personal Access Token
-
-You will need your personal access token credentials to authenticate when you clone the repository and when downloading objects from Git LFS
-
-[Create a personal access token with the 'repo' scope.](https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token)
-
-During the clone operation, you will be prompted to enter a password. Your token will be used as the password. You will also be prompted a second time for Git LFS.
-
-### (Recommended) Verify you have a credential manager installed to store your credentials 
+If Git LFS is not installed, download and run the installer from: https://git-lfs.github.com/.
 
-Recent versions of Git install a credential manager to store your credentials so you don't have to put in the credentials for every request.
-
-It is highly recommended you check that you have a [credential manager installed and configured](https://github.com/microsoft/Git-Credential-Manager-Core)
-
-For Linux and Mac, use the following commands to store credentials 
-
-Linux: 
+### Install Git LFS hooks 
 ```
-git config --global credential.helper cache
-``` 
-Mac:
-```
-git config --global credential.helper osxkeychain
+git lfs install
 ```

 ### Quick Start Build Steps
 
 1.  Create a writable folder to cache 3rd Party dependencies. You can also use this to store other redistributable SDKs.
     
-    > For the 0.5 branch - Create an empty text file named `3rdParty.txt` in this folder, to allow a legacy CMake validator to pass
-
 1.  Install the following redistributables to the following:
     - Visual Studio and VC++ redistributable can be installed to any location
     - CMake can be installed to any location, as long as it's available in the system path
-    - WWise can be installed anywhere, but you will need to set an environment variable for CMake to detect it:  `set LY_WWISE_INSTALL_PATH=<path to WWise>`
+    - (Optional) Wwise can be installed anywhere, but you will need to set an environment variable for CMake to detect it:  `set LY_WWISE_INSTALL_PATH=<path to Wwise>`
     
-1.  Navigate into the repo folder, then download the python runtime with this command
-    
-    > For the 0.5 branch - Set this environment variable prior to the `get_python` command below:
-    > ```
