Getting Started with Celeste Modding

Celeste modding is one of the most accessible scenes in PC gaming — install Olympus, click to install Everest, browse and install custom maps from within Olympus. The whole setup takes under five minutes.

Step 1 — Install Olympus

Olympus is the community mod manager. Download from the Everest project's website. Run; Olympus auto-detects your Celeste install.

Step 2 — Install Everest via Olympus

Olympus's main screen prompts to install Everest. Accept. Olympus patches Celeste's executable with the Everest hooks.

After install, launching Celeste loads Everest alongside.

Step 3 — Browse and install custom maps

Olympus's Mod Browser pulls from Gamebanana and Mons. Filter:

• Maps — custom levels and campaigns.
• Mechanics — gameplay tweaks (custom physics, alternative controls).
• Helpers — framework mods other maps depend on.
• Cosmetic — skins, sounds.

Three popular first picks:

• Strawberry Jam Collab — a massive community-collaboration campaign with hundreds of contributor levels.
• Glyph — single-author custom campaign, polished.
• Spring Collab — another major collab. Many short levels.

Each map auto-downloads through Olympus.

Step 4 — Launch and play

Launch Celeste through Olympus or via Steam (Everest loads either way). The main menu now has a Mod Maps section listing your installed custom maps.

Pick a map, start playing. The map appears as a separate chapter alongside vanilla Celeste's content.

Step 5 — Configure Everest

Olympus → Settings. Many Everest options control:

• Console hotkeys (in-game debug tools).
• Performance settings (frame rate caps, etc.).
• Speedrun timer overlays.
• Mod-loading behaviour.

Common gotchas

• Everest not installed. Run Olympus's Everest install prompt.
• Custom map missing helpers. Helper-mod dependencies. Olympus usually catches these; if not, install required helpers manually.
• Map crashes on specific room. Often a custom-physics bug in the map. Report on the map's Gamebanana page.
• Multiplayer not supported. Celeste is single-player only. Speedrun races coordinate timing externally.

Celeste's modding scene is the most well-curated platformer-modding scene in PC gaming. The Strawberry Jam Collab alone is more content than the base game. Worth a play even if you never modded a game before.
