Examples Needed
This page should have explicit examples of Lie groupoids. Some examples should include
 * Lie Groupoids from the Analytification of smooth groupoid schemes over $$\mathbb{C}$$
 * Actions of $$U(1)$$ and discrete subgroups on $$S^n$$
 * Quotient stacks from affine actions e.g. $$\mathbb{Z}/2$$ acting on $$\mathbb{R}^2$$ by

\begin{align} x \mapsto -x & y \mapsto -y \end{align} $$
 * Lie groupoids from homogeneous spaces — Preceding unsigned comment added by 50.246.213.170 (talk) 00:46, 5 August 2017 (UTC)
 * Another interesting example is the morphism of Lie-Groupoids induced by an action on a fiber bundle. — Preceding unsigned comment added by 128.138.65.181 (talk) 01:07, 20 August 2017 (UTC)

Further details needed
Some of the examples are incomplete, as they do not explain how the Lie Groupoid is actually obtained; most notably, it is not explained how a foliation gives a Lie Groupoid. --AlephMal (talk) 16:12, 10 January 2020 (UTC)
