Posting this to clean it all up a bit:
Following is a step-by-step guide of what you need to do:

1. Import weakauras and elvui profile
https://wago.io/ryJ09mzVm - ElvUI profile
https://wago.io/HJ-_j7zEm - Rogue weakauras #1
https://wago.io/B1N9oQGE7 - Rogue weakauras #2
https://wago.io/ByHoi7MV7 - Rogue weakauras #3
https://wago.io/r1JTj7MV7 - Shadow techniques tracker (rogue, subtlety)

2. Make sure you have following addons
Addonskins - for timers and borders on elvui and weakauras
ElvUI Shadow & Light - Just provides more functionality for elvui, such as the character pane etc.
Sharedmedia - Handles media (fonts in our case) across different addons
SharedMediaLib

3. Download details and bigwigs profiles (download button is in the top right corner)

For what to do with those files, follow this video:

 TO CLARIFY: THIS GOES IN WTF/ACCOUNT/ACCOUNTNAME/SAVEDVARIABLES FOLDER - NOT THE CHARACTER'S FOLDER

4. If you downloaded AddonSkins and  you're still missing timers use this video.

5. Select the correct profiles
Type /bw, go to Profiles and select profile "Rogue BFA BW"

Next you type /details options, go to profiles tab and select profile "hehejmy" (you might have to resize one of the windows here, press unlock in the bottom right corner and drag)

6. "How do I add fonts to x addon?" Download these files and place it into World of Warcraft\Interface\AddOns folder :

7. Optional help with action bars
Here's a video to open actionbars if you want to disable/hide them or enable them & how to enable keybind text, and also how to adjust your actual keybindings.
