Getting Forge 1.9 to work with Optifine HD 1.9?

For the love of everything that is good and holy… Here's the situation… So I'm trying to get Forge 1.9 (using the installer) to play nice with 1.9 Optifine… (and if I ever get those to work together, I also need to tack on Liteloader). So there are 7 billion versions of Optifine I see, but no real clarifications on what the dumb letters mean at the end of the name. So I downloaded Optifine 1.9 HD. I followed what every tutorial on the internet says of installing forge and then install Optifine, but it crashes every time.
So I'm really new to modding… But I've gotten other mods to work… Just not stupid Optifine. Please help? Am I missing something obvious?

If I ever get this working, I will also need to add liteloader onto it too… But the liteloader 1.9 beta installer works like a dream so I don't think there will be many problems? Maybe? I got it to work just now, there's now a bit of an odd and different method, but It works!

Get the latest version of Forge and Optifine. Latest versions as of 3/19/16: (1.9-Latest Installer Forge 11.15.1.1765) (Optifine 1.9.0_HD_U_A0_pre)
Install them both, do not put the Optifine Installer in the "mods" folder.
After installing them both, go to the Minecraft directory.minecraft
Go to.minecraft/libraries/optifine/OptiFine/1… And copy the "1.9.0_HD_U_A0_pre.jar" to clipboard.
Paste it in the "mods" folder.
Open MC Launcher and edit the profile to "Use version: 1.9-Forge11.15.1.1765"
Press play.
Unfortunately, this didn't work with the shaders mod in the mods folder, as it'd give me a crash. I'm not entirely sure if it will cope with other mods as well. But I do know it worked fine with the Hit Splat Damage Indicators mod.
