To set up modpacks, the first thing you need to do is sign in to your Minecraft account. This is super important so you can use and manage your mods in the game.
- Click Select Account on the right side of the screen, and Sign in with your Minecraft Account.
- Log in using the Microsoft account associated with your Minecraft purchase to play the game with modpacks.
💡 Tip: You can add multiple Minecraft accounts to the Modrinth app once you have added the firs one.
Now that we’ve signed in, it’s time to install some Modpacks.
By default, when you open the Modrinth App, you’ll see the Home Menu displaying modpacks sorted by relevance. However, I’ll guide you on how to explore deeper and refine your Modpack selection.
- Click where it says “Discover a modpack” on the left top corner.
It will take you to the “Discover content” page, where you will be able to change from Modpacks to even Shaders, and on the right side you can filter to look for the specific Modpack that you want to get.
⚠️ Important: When navigating the filters on the right-hand side, use your mouse wheel to scroll, as the scroll bar may not function properly.
- Click Install on the modpack you wish to use, and wait for the installation process to complete.
For example, I will be installing the Cobblemon Official Modpack, which transforms Minecraft into a Pokémon like game.
- Once you install the modpacks you want, Click the Library icon on the left, where you will see all your experiences.
💡Tip: Hover the mouse over the modpack and launch the game directly by clicking the green button, or click on the modpack name to access deeper configuration options, such as enabling or disabling individual mods or shaders.

- In the next window, click on “Default Instance Options” to proceed.
- Drag the Memory Allocation slider to the amount of memory you want to use. For example, setting it to 4096 MB will give your game 4 GB of RAM.
💡 Tip: It’s best not to use more than half of your computer’s available RAM. This adjustment ensures your game runs smoothly and efficiently without slowing down your PC.
