## Installing Conda

```

```

## Installing mkdocs

```
pip install mkdocs mkdocs-material[imaging] pymdown-extensions
```

## Customizing Terminals

```sh
sudo apt install wmctrl
```

We can then create a command that starts up our three development terminals:

1. One for Claude Code

```sh
#!/bin/bash

sleep 2

# Startup Terminal 1 with Claude Code at (0,50)
lxterminal -t "Claude Code" --loginshell -e /usr/bin/claude --dangeriously-skip-permissions --geometry=80x24 &
# The -e option format is gravity,x,y,width,height (in pixels). Use 0 for gravity (default).
sleep 0.5
wmctrl -r "Claude Code" -e 0,0,0,800,400

# Terminal starting in a specific directory
lxterminal --working-directory=/home/pi/projects &

# Terminal that runs a command
lxterminal -e "htop" &
```
## GitHub Settings

```sh
git config --global user.email "suejohnson@example.com"
git config --global user.name "Sue Johnson"
```

## Screen Capture Tool

```sh
sudo apt install grim slurp
```

```sh
grim -g "$(slurp)" screenshot.png
```

## Open

```sh
which open
/usr/bin/open
(base) dan@raspberrypi:~ $ ls -l /usr/bin/open
lrwxrwxrwx 1 root root 22 Apr 25  2021 /usr/bin/open -> /etc/alternatives/open
(base) dan@raspberrypi:~ $ ls -l /etc/alternatives/open
