Installing Everest

Olympus - Cross-platform Everest Installer

YOLO! This fancy tech is actively worked on, so don't be surprised if it blows up in your face.
Please report all bugs to the Everest Team in #modding_help on the Celeste Discord server!
Feel free to scroll down to the manual installation instructions if this doesn't work.

• If you are on Windows:
  • Download olympus.exe from GameBanana and run it.
    • ... or download it directly from GitHub.
  • If Windows SmartScreen blocks it, tell it to run anyway.
  • If your antivirus blocks it, let them analyze it as a false positive and if possible, send them here.
    Olympus can update itself and injects Everest code into Celeste.exe but both are open-source.
  
  
• If you are on macOS:
  • Download the latest autobuild.
    Click the "5 published" button under "Related", then "macos.main" to download it.
  • Unzip the zip inside of the zip. Zipception!
  • Drag the Olympus app into your Applications folder.
    If you leave it in your Downloads folder, some things like self-updating might not work!
  • Hope that it works.
    Sadly our code monkeys top scientists aren't trained with Macs.
    You might need to right-click, open, then allow running applications from unverified developers.
    If you are a macOS user and are willing to help us test stuff: let us know on Discord!
  
  
• If you are on Linux:
  • Download the latest autobuild.
    Click the "5 published" button under "Related", then "linux.main" to download it.
  • Unzip the zip inside of the zip. Zipception!
    The resulting folder will be your Olympus "installation" folder.
  • Run install.sh in a terminal to install the one-click installer handler and application icon.
  • Run Olympus from your applications list (or olympus in the folder) and hope that it works.
    If it doesn't, here are some things to check:
    • If the bundled Love2D doesn't work and your distro provides it via the package manager, try that.
    • If you have Mono installed on your system, try updating it.
    • If you are on ArchLinux, you can give the unofficial AUR package a try.
    • Alternatively, you could also try out the Flathub package.
    If you're still out of luck, feel free to ask for help on the Celeste Discord.
  
  
• No matter what platform you are on:
  • If there's a red ! on the options button, update Olympus first.
  • Press on the "Manage" button on the left side.
  • Add your Celeste installation(s), change the name(s) as you see fit.
  • Go back (top left corner) and press the huge Everest installation button.
  • Select an Everest version and hit the long "Install" or "Update" button.

Everest.Installer for Windows (old)

• Download everestinstaller.exe and run it.
• If Windows SmartScreen blocks it, tell it to run anyway.

Cross-platform manual installation

If you need to scroll down this far, please let us know why so we can improve Olympus.
If you're familiar with the command line, you can use mons to install Everest and manage your mods.
You can also follow the installation instructions below to install Everest manually!

• Download the latest autobuild for the branch you want:
  • stable branch: best if you don't need any new features and just want to play mods.
  • beta branch: best to develop your mod or to have others test your mods on, with earlier access to new features.
  • dev branch: gets updated very frequently as development of new features goes on.
  Click the "1 published" button under "Related", then "main" to download it.
• Open the directory where Celeste.exe is located:
  • With Steam: right click Celeste in your library, then "Manage" > "Browse local files".
  • On macOS: follow the step above if you own the game on Steam. Right click the Celeste application, and choose "Show Package Contents". After that, go into the Contents directory, then Resources.
• Open the main.zip file you downloaded, then copy the contents of the main folder to the directory where Celeste.exe is: Celeste.Mod.mm.dll should be right next to Celeste.exe.
• Run the appropriate MiniInstaller executable for your operating system:
  • On 64 bit Windows, run MiniInstaller-win64.exe.
  • On 32 bit Windows, run MiniInstaller-win.exe.
  • On Linux, run MiniInstaller-linux.
  • On macOS, run MiniInstaller-osx.

Installing mods

• Find a mod that you want to play with on GameBanana, or in the "Download Mods" section of Olympus.
• Press the 1-click installation button.
  • If the 1-click installer doesn't work, put the mod .zip into the Mods directory where Celeste is, or drag the .zip on Olympus to install it.
  • For prototyping and development, feel free to use a folder instead of a .zip
• That's it. No need to extract anything.
