How do I download UE 5.5?

JSFILMZ is suing 5.5 in this video: https://www.youtube.com/watch?v=-I1Y0s_tZa0 and I noticed comments were saying you can get it on the github but all I’m seeing is 5.4.2: https://github.com/EpicGames/UnrealEngine/releases

How do I get 5.5? Thanks

at my understanding whenever new version is out, the release branch is being versioning up so now release is 5.5, be sure you know what ur doing.

The ue5-main branch gets all the latest updates as they are being developed.

https://github.com/EpicGames/UnrealEngine/tree/ue5-main

So I’m confused. 5.5 is avaliable though? Is this the page with the instructions I should be following? Downloading Unreal Engine Source Code | Unreal Engine 5.4 Documentation | Epic Developer Community

My understanding is that UE5-main branch is 5.5, the latest release branch was 5.4.2. Basically the main branch gets all the latest updates, (it was updated 3 hours ago as I’m writing this.)

You need to follow the the documents to download the engine’s Source Code, then Build the engine using Visual Studio*

*You’re gonna need 200 - 300+ GB storage space to build the engine and it’ll take around 1 - 4+ hours to build depending on the number of CPU cores and the amount of RAM you have.

Okay seems simple enough. NOT. Do you have anything specifically on doing this or how to? Thanks for the replies

I believe something is missing.
I’ll explain what I did…
First I downloaded it via Github, then I switched to UE5-main
After everything was synchronized, I ran “Setup.bat”, when I finished I ran “GenerateProjectFiles.bat”, then I opened UE5.sln, here I left it in "Development Editor, Win64.
I right-clicked on “UE5” and clicked on BUILD, after about 4 hours it compiled.
Then I right-clicked on “UE5”, Debug, Start New Stance.
And everything failed in the end, I know I have 221 GB created, 374,715 Files, 56,044 Folders, but the “UnrealEditor.exe” does not exist inside the folder “D:GitHubUnrealEngineEngineBinariesWin64”

Ok. I will give up, because this is my second test since JSFILMZ launch his videos and fail again yesterday.
If anyone can share UE5.5 with us to test in our PC, thank you, but i will delete 221 GB of unused files again.
