trouble installing tintin plus on the mac

For the purpose of clarity I'm pasting these here. I've tried to hand right this in, from one machine to another, and maybe I'm getting the command sequence wrong cause the first command just won't run at all, and admittedly, I know only that the terminal is the mac's version of dos for the windows environment. I tried initially selecting and pasting on the mac with voiceover, but that didn't go well at all. Here's the instructions I have.
Step 1: Install Homebrew
Go into terminal and type:

ruby -e "$(curl -fsSL
https://raw.githubusercontent.com/Homebrew/install/master/install)
"

You may need to:
Nano ~/.zshrc
And in that file:
export PATH="/opt/homebrew/bin:$PATH"

Then control+x to close that file. It’ll ask you if you want to save the file, enter Y. It’ll then ask you what you want to call it; just hit enter.

Step 2: install tt++

brew install tintin

Step 3: Install Sox

brew install sox

Step 4: Make a "games" folder in your home directory, and put the tt.tin file in that folder.

Step 5. Run the game

Go into terminal and type:

tt++ games/tt.tin
That will start up Tintin and load my global scripts for all muds.

Step 6. Connect to a game

If you want to add other worlds, type “add world without the quotes.  (Going to work on a blank .tin file being created in the worlds/world name-world
url folder that is created upon world creation via the terminal client).
If you want to delete a world: delete world name. (Going to make it so that the folder to which the world belongs is deleted too, or maybe where you are
given a prompt as to what you want done with it.)
If you want to see your world list, just type “connect”. 

But not so fast: now we have to set up the screen reader for terminal, which is not required, but highly recommended.

You can find these instructions online, but this file is here for the technically challenged and/or for convenience.

Follow these instructions in order as they will make the process of configuring your computer much easier.

1. Install Python:

brew install python3

2.  Clone the Screen Reader repository:

git clone
https://github.com/tspivey/tdsr.git

3.  Move to the Screen Reader Folder:

cd tdsr

*** This folder should be located in your home directory. Do not remove it. ***

4.  Install it:

pip3 install -Ur requirements.txt

5.  Run the Screen Reader:

tdsr/tdsr

*** Notes for the Screen Reader taken from readme. ***
## Terminal setup
Open Terminal preferences, under Profiles check Use Option as Meta key.
## Keys
(alt refers to the meta key.)
* alt u, i, o - read previous, current, next line
* alt j, k, l - read previous, current, next word
* alt m, comma, dot - read previous, current, next character
* alt k twice - spell current word
* alt comma twice - say current character phonetically
* alt c - config.
* alt q - quiet mode on/off. When on, text is not automatically read.
* alt r - start/end selection.
* alt v - copy mode. Press l to copy the line the review cursor is on, or s to copy the screen.

## Configuration
Once in the config menu, you can use:
* r - set rate.
* e - Set typing echo
* v - set volume (value between 0 and 100).
* p - toggle symbol processing.
* d - set cursor delay (in MS). The default is 20.
* Enter - exit, saving the configuration.

## Symbols
Symbols can be added in the configuration file (```~/.tdsr.cfg```),
under the symbols section.

The format is:
```
character code = name
```
Because of how the config system works, it's best to do this with one TDSR open, then exit and re-launch to see the changes.

*** Tweaks ***

You don’t have to do this, but I recommend it for ease of use.

Here’s how to make the screen reader run on terminal start up:

1.  Go into terminal settings with command comma.
2.  Make sure you’re in the profile section. You can find out by interacting with the toolbar and selecting “profile”. 
3.  Select the keyboard tab and check the box that says “use alt as meta keys”. 
4.  Go to the “Shell tab” and check the box that says, “Run command”.
5.  In the edit box that follows enter tdsr/tdsr
6.  Check the box that says, “Run inside shell”.
7. Close settings.
You may have noticed that voiceover and the screen reader speak at the same time, and this is annoying, so let’s tell VO to shut it when terminal’s the
active window.

1.  Go into voiceover utilities with VO F8.
2.  Go down to “activities and click add.
3.  Call the activity whatever you’d like such as “Accessible terminal”.
4.  Click the checkbox that says “voices”.
5.  Click “set” and  the the checkbox for “mute speech”.
6.  Go to “use this activity for”, and select “terminal” in the combo box.
7. Click “Close” and leave voiceover utility.

If you ever want to undo this, just go back into Vo utilities and activities, and uncheck the speech box. Toggling that off and one will do and undo this
tweak.

Final notes:
If you want to change your system voice, go into system preferences and accessibility. Then go down to speech.  Or go to “dictation and speech” in system
prefs if you use an old dinosaur as I sometimes do.
Your system voice can go faster than the 100 percent that the system prefs says. So when you’re changing the rate with the screen reader keep this in mind.
For example, I think I have mine set at 550.

That is the sum total of what I have to work with. That's why I was asking for help via remote connection, or to maybe get with someone on clubhouse, team talk, or skype to work out the problem. I'm sure this is coming down to operator error, and inexperience. Thanks for any other suggestions you might have.
