Creating a clean gh-pages branch

This is the sequence of steps to follow to create a root gh-pages branch. It is based on a question at [SO]

cd /path/to/repo-name
git symbolic-ref HEAD refs/heads/gh-pages
rm .git/index
git clean -fdx
echo "My GitHub Page" &gt; index.html

Why I think Immediate Mode GUI is way to go for GameDev tools

	// Creating a node graph editor for Dear ImGui
	// Quick sample, not production code!
	// This is quick demo I crafted in a few hours in 2015 showcasing how to use Dear ImGui to create custom stuff,
	// which ended up feeding a thread full of better experiments.
	// See https://github.com/ocornut/imgui/issues/306 for details

	// Fast forward to 2023, see e.g. https://github.com/ocornut/imgui/wiki/Useful-Extensions#node-editors

	// Changelog
	// - v0.05 (2023-03): fixed for renamed api: AddBezierCurve()->AddBezierCubic().

	// SAT collision check and resolution
	// Public domain
	// Usage example:
	// if (testCollision(obb1, obb2, mtv)) { // obb1, obb2 - sf::RectangleShape, mtv - sf::Vector2f
	// obb1.move(mtv);
	// }
