# Manifold Atlas:Wiki syntax

This page collects some simple but useful tips about the Wiki syntax. The MediaWiki Handbook is a good reference for the wiki software: see especially the section for editors.

## Contents

You create hyperlinks inside the Manifold Atlas by writing [[page name|link text]]. For example

[[Surfaces|2-dimensional manifold]]


If you wish to link to a Wikipedia page, use the above format with the page name: Wikipedia:page_name. For example

[[Wikipedia:Differentiable_manifold|smooth manifold]]


### Links to sections and subsections

You can refine your hyperlinks to sections and even subsections of web-pages. For example

[[5-manifolds: 1-connected#Invariants|linking form]]


produces the link linking form, which goes directly to the invariants section of the page on simply-connected 5-manifolds.
