If you still need to install tModLoader refer to the tModLoader guide for players.
Before you begin, you will need two things, the ".NET 8 SDK" and a suitable IDE. Once you have these installed, you should start with the Basic tModLoader Modding Guide.
Choose your favorite IDE to mod with tModLoader. Refer to the development section on the homepage. For the best mod making experience, using Visual Studio is highly recommended.
Install the .NET 8 SDK by downloading the installer, running it, and following the instructions. Download the installer for the latest SDK release labeled "x64" corresponding to your operating system. Don't download the .NET 7.0 or .NET 6.0 versions, those will not work.

To verify that you have the ".NET 8 SDK" properly installed, you can open a command prompt and type dotnet --list-sdks and press enter. If you see a result with a version starting with the number 8, it is installed.
The folders shown should show the Program Files folder not the Program Files (x86) folder. If you see the 86 folder, that means you installed the 32 bit SDK by accident. You can uninstall it and then install the correct version or install the correct version and adjust the PATH variable so that the 64 bit SDK shows up instead.
If you are new to modding, it is recommended to start with the starter guide. You can then move on to the easy guides.
