Sounds like you pressed the "Clone or download" button on the Github page, which downloads the git repo (that is, source code). Normally, compiled plugins are available in
the Releases section.
None of the binaries I'm aware of are up to date (the latest release is almost four years ago, and so is the attached plugin file in the main post), so you have the following options:
- Copy the contents of tf2attributes.sp into Spider and hit the "Compile" button on the right. Press the "Download" button next to it to get the .smx file, then follow the rest of the steps.
- Use my build, which have a few additional features and are prebuilt. The same 3-step instructions still apply with those files.
- Click the "Get Plugin" link below, which is the same as the first option, except it's compiled through the forum.
