I use PlantUML a lot. It's what I use for drawing all sorts of diagrams and it's handy because of its easy markup (once you get used to it) while making things easy to maintain as projects grow (thanks to version control)

This gist explains how I do my PlantUML workspace in a project.

• The idea is to keep a globals directory for all diagrams to follow (like the "stylesheet" below) to keep things consistent.
• I use a stylesheet.iuml file that keeps the use of colors consistent through use of basic FOREGROUND, BACKGROUND and ACCENT colors.
• The style-presets.iuml file defines these colors so you can make "presets" or "themes" out of them.
• As stated in the stylesheet.iuml, you'll need the Roboto Condensed and Inconsolata fonts for these to work properly.
• You can choose to either run the PlantUML jar over your file/s, or use an IDE like VSCode with the PlantUML extension. Here's a preview of example-sequence.puml for example: https://imgur.com/Klk3w2F

jq will sort (-S) the whole file (.) and compare STDOUT (<()) with diff

diff <(jq -S . A.json) <(jq -S . B.json)

# 1. First of all of course get Manjaro:
https://manjaro.org/get-manjaro/

# I recommend using Etcher to copy the image to your USB:
https://etcher.io/

# 2. Before installing make sure:
# - Secure boot is disabled in BIOS
# - Your SSD, HDD or NVME drive is set to AHCI instead of RAID
# - Fastboot should be on Auto or minimal, but this shouldn't matter to much
