## General remarks on editing

You should feel welcome to contribute, even if you think what you write doesn't match the 'house style'.

In that case, this page is more to explain the meaning behind any minor changes that may be applied to your work after it has been submitted.

Over the course of prolonged contribution, it is considered both polite and very desirable that contributors put effort in mastering and adhering to house style, which is located at Help:House Style.

Should there be any questions, Help:Questions is the place to raise issues.

## Page Editing

The purpose of this section is to describe the general structure that the various sections most used on $\mathsf{Pr} \infty \mathsf{fWiki}$ are to adhere to. While this naturally intersects with house style at some points, an attempt is made to separate the global editing instructions and section-specific instructions.

This reference provides the general outline on creating pages and instructions for specific sections; for the rest, see Help:House Style. Furthermore, this page does not dwell on details pertaining to the MediaWiki architecture; the reference for such things is Help:Wiki Editing.

### Creating a Page

In general, pay attention to the fact that page names are case sensitive.

Pages can be created in several different ways. Before creating a page, please put some effort in ensuring that the anticipated content is not already up somewhere else on $\mathsf{Pr} \infty \mathsf{fWiki}$. This does also apply when following a red link; after all, the page in question may simply have a (slightly) different name.

#### By Searching

First, search for the page name which you would like to create. If this page has not already been created then you will see something that looks like this:

There is no page titled "Proof Name". You can create this page.

Clicking on create this page will open the page editing window.

#### Direct URL

If you know for sure that the proof is not on the site, then simply type that name into the URL. For example, if you wanted to prove the Riemann Hypothesis, you would type:

http://www.proofwiki.org/wiki/Riemann Hypothesis

If this page does not exist then, you will get a single line saying:

There is currently no text in this page, you can search for this page title in other pages or edit this page.

Clicking edit this page will open the editing page where you can edit the page.

### Page Naming

For all types of pages, major words in the title of the page should be capitalized. For example: Subring Generated by Unity of Ring with Unity. It is also generally better not to start a page name with "A" or "The", as this makes it significantly harder to find pages alphabetically in their categories. For example: Pythagorean Theorem, not The Pythagorean Theorem.

So as to promote consistency, be informed that in particular, the words 'iff', 'implies', and 'under' are not considered to be "major", and so are ought to be used in their lowercase form when naming a page.

#### Naming Proofs

It is not necessary to begin the name with "Proof of ...", and this should be avoided. Since $\mathsf{Pr} \infty \mathsf{fWiki}$ is a collection of proofs, it is assumed that each page is going to be a proof of something. This also makes searching for articles much easier.

If the name of a page contains mathematical statements, the following formatting practices should be adhered to:

• Put no spaces between numbers/elements that are added, subtracted, divided, or multiplied together.
Eg: (1+2)x3.
• Do, however, put spaces between elements that are put into equality or inequality with one another, and please use != to signify inequality.
Eg: 1 = 3/3 != 3/4.

#### Naming Other Pages

When you would like to create a page for a definition, all you have to do different from naming a proof is to add Definition: in front of the name. So for example if you wanted to create a page for the definition of calculus you would name the page:

Definition:Calculus

Also, after you create the page, be sure to add the definition to the appropriate "Definitions" categories (see Category:Definitions).

The same method that is used for Definitions is also used to name and categorize axiom and symbols pages. Simply substitute Symbol or Axiom for Definition: in the page name and, mutatis mutandis, in the category name.

#### Disallowed Characters

The following characters should not be used in page names:

### No longer supported

The following $\LaTeX$ commands are not supported in MathJax, but may still be present in some pages. When found they need to be replaced.

For $\lor$: \or to be replaced by \lor
For $\land$: \and to be replaced by \land
For $\R$: \reals to be replaced by \R
For $\varnothing$: \O to be replaced by \varnothing
For $\exists$: \exist to be replaced by \exists
For $\operatorname{sgn}$: \sgn to be replaced by \operatorname{sgn}

For producing fixed width text in math mode: \texttt needs to be replaced by \mathtt.

If you find any more examples, add them here.

### External references

It may not be exactly the same version of $\LaTeX$, but I always find this page helpful as a first, quick overview:

This is also a good reference page, pertaining to MediaWiki $\LaTeX$:

but be aware that not all commands are supported.
