Where does the user add mamba solver?

After downloading Miniforge3, it's not clear how to do the next step. We need to add "Open Miniforge Prompt". On Windows it can be done from Start -> Miniforge3 -> Miniforge Prompt

 The first thing we will do is to install the mamba solver and add it to our `.condarc`.

Also, this doesn't appear anymore

Lines 57 to 72 in ed5995a

 If that worked you should see: 
  
 ```

 NOTE: You are using the EXPERIMENTAL libmamba solver integration. 
  
 If something is not working as expected, please: 
  
 1. Go to https://github.com/conda/conda/issues/new/choose 
 2. Choose the "Libmamba Solver Feedback (Experimental Feature)" option 
  
 Thank you for your help!

libmamba should be the default solver now. I guess we can just remove any references to it from the instructions.
