==Prerequisites==
* Minecraft Java Edition is already installed.
** I am currently using 1.15.2.  This should be a universal instruction set for all versions unless something major changes in Minecraft.

==Installing Optifine==
* If you're stuck at any time, you can watch the companion video here (no sound)

===Getting Optifine===
'''Note:'''<br><br>After upgrading to 1.15.2, I thought shaders were lost to me.  I've read so many website comments concerning "just install 1.14.4 and it will work" and I've never gotten that to work.  I have yet to find a set of directions out there that have any mention of Preview Versions on Optifine.net and one day after some frustration, I clicked the Preview Versions link (I didn't realize it was a link previously).  Insert scene from Pulp Fiction when the briefcase opens here.<br><br>That one item prompted this entire instruction set.  I hope someone finds it useful.<br><br>
# Go to [https://Optifine.net/downloads Optifine.net/downloads]
#* '''''Only use downloads from the official Optifine.net website.'''''
#* At the time of this recording, it appears that Optifine only goes up to 1.14.4.  What do we do?
# Click on Preview Versions at the top
#* An additional batch of downloads should now be visible. We are looking for 1.15.2, you can choose whatever version you are seeking.
# Download the appropriate file
#* preview_OptiFine_1.15.2_HD_U_G1_pre30.jar 
#* Both download links have ads and screen clutter: I suggest you grab from the mirror.
#* We will assume it goes to your '''Downloads''' folder

===Installing Optifine===
# Open a Command ''or'' Powershell prompt
#* Some users may be able to hold shift and right click within the folder, then select '''Open [Command Prompt or Powershell] Window Here'''
#** If you have Powershell, wait for the window to open and then type '''CMD <enter>''' to shift over to Command Prompt
# Type '''java -version <enter>''' at the prompt
#* If you get a version you skip to '''Launching the Optifine Installer''', otherwise you probably got a ''java is not recognized recognized'' error message and will need to continue to '''Get the Path to Java'''.  We're still assuming you have a working version of Minecraft Java Edition installed.
====Get the Path to Java====
* I do not have java installed at the system level, however as I have Minecraft Java Edition running, the java executable is available somewhere, I just need to find it and get the path.
# Windows 10: Right click the Minecraft shortcut and open '''Properties''', then '''Open File Location'''
# Click on the following folders in order: Runtime, JREx64, bin
# Scroll down to "java.exe" 
# Hold '''SHIFT and right click 'java.exe'''', then select '''COPY AS PATH'''
#* You will now have the path to Java in your clipboard (you can test this by opening notepad and pasting (CTRL+V))
#* Mine happens to be '''"D:\Games\Minecraft Launcher\runtime\jre-x64\bin\java.exe"'''
#* Leave the folder window open in case you need to grab the full path again.

===Launching the Optifine Installer===
* Make sure you either have java installed (java -version) or the path to the java executable and that your command prompt window open and is where the downloaded Optifine file is (we're assuming the Downloads folder).  
# type the following command as it applies to your set up:
#* Example format: java -jar path/to/preview_OptiFine_1.15.2_HD_U_G1_pre30.jar
## Java is installed:
##* '''java -jar preview_OptiFine_1.15.2_HD_U_G1_pre30.jar <enter>'''
## Java is not installed:
##* '''"D:\Games\Minecraft Launcher\runtime\jre-x64\bin\java.exe" -jar preview_OptiFine_1.15.2_HD_U_G1_pre30.jar <enter>'''
##** I pasted the clipboard (CTRL+V) to the command prompt window to get the "D:\Games\Minecraft Launcher\runtime\jre-x64\bin\java.exe" path in place, then I typed  -jar preview_OptiFine_1.15.2_HD_U_G1_pre30.jar

===Optifine Installer===
# The installer window should be open now and it will have a path already entered.  We are going to assume that this is correct for most people.  
#* Click INSTALL
#** C:\Users\<your account name>\AppData\Roaming\.minecraft
#** or type %appdata% <enter> from the search bar and you will see the .minecraft folder
# Click OK when the Optifine is successfully installed window pops up
==Minecraft==
===Get A Shader Zip===
* You'll need a shader zip file for the next step.  If you have one, great skip ahead.  If not, go get one.  For 1.15.2 I have the following zip files
