I finished a guide yesterday, in the process of adding some pictures to it: https://lemmygrad.ml/post/9911266
It's really not that complicated to install crush! I promise haha. If she is on Windows it's literally copy and paste a command in powershell (winget install charmbracelet.crush), close powershell, open cmd, cd to a folder, type 'crush' and send, and it will open.
Then in crush panel type Thinking mode to get deepseek, hit enter,
Then make a deepseek API key and top it up with 5$ on platform.deepseek.com, copy API key, paste with Ctrl+Shift+V, hit enter, and it will just work. Try to send hello to make sure you're connected.
