You might want to learn simply [[how to start a page]], and you might want informal [[tips on contributing to Wikipedia]]. If you want the details about how to edit a Wikipedia page, though, you've come to the right place.

[[Wikipedia]] is a [[wiki]], meaning anyone can edit nearly any<ref name="protection"/> page and improve articles immediately. You do not need to register to do this, and anyone who has edited is known as a ''[[Wikipedia:Wikipedians|Wikipedian]]'' or ''editor.'' Small edits add up, and every editor can be proud to have made Wikipedia better for all. There are two editing interfaces: the new [[Wikipedia:VisualEditor|VisualEditor]] (VE) and classic [[Help:Wikitext|wikitext]] editing (wiki markup), which uses the [[Help:Introduction to editing with Wiki Markup/1|Source Editor]].
 
== Editing articles ==
It's very easy to edit a Wiki page. Simply click on the "Edit
{{see also|Wikipedia:FAQ/Editing|Help:Introduction to editing with VisualEditor/1}}
this page" link at the top or bottom of a Wiki page to change the page itself, or click on the "Other Namespaces: Talk" link at the bottom to discuss it. This will bring you to a page with a text box containing the editable text of that Wiki page.
=== Content style and policies ===
{{see also|Wikipedia:Core content policies}}
An [[Wikipedia:Writing better articles#Information style and tone|encyclopedic style]] with a [[Wikipedia:Writing better articles#Tone|formal tone]] is important: straightforward, [[Wikipedia:Summary style|just-the-facts]], instead of essay-like, argumentative, or opinionated. The goal of a Wikipedia article is to create a comprehensive and [[Wikipedia:Neutral point of view|neutrally written]] summary of existing mainstream knowledge about a topic. Wikipedia does not publish [[Wikipedia:No original research|original research]]. An encyclopedia is, by its nature, a [[tertiary source]] that provides a survey of information already published in the wider world. Ideally, all information should be [[Wikipedia:Citing sources|cited]] and [[Wikipedia:Verifiability|verifiable]] by [[Wikipedia:Reliable sources|reliable sources]]. Sourcing requirements are significantly stricter in [[Wikipedia:Biographies of living persons|articles on living persons]].
{{anchor|Edit window}}
=== Edit screen(s) ===
Editing most Wikipedia pages is simple. Wikipedia uses two interface methods: classic editing with the [[Help:Introduction to editing with Wiki Markup/1|Source Editor]] through [[Help:Wikitext|wikitext]] (wiki markup), and a new [[Wikipedia:VisualEditor|VisualEditor]] (VE).
 
Wikitext editing using the Source Editor is chosen by clicking the <kbd>Edit source</kbd> tab at the top of a Wikipedia page (or on a [[Help:Section|section-edit link]]). This opens an editable copy of the page, showing all the wikitext used there, and the Source Editor toolbar offers simple menu options to add or change the formatting. Wikitext is used extensively throughout Wikipedia for such things as [[Help:Link|hyperlinks]], [[Help:Table|tables]] and [[Help:Columns|columns]], [[Help:Footnotes|footnotes]], [[Wikipedia:Inline citation|inline citation]], [[Help:Special characters|special characters]] and so on. The Source Editor lets users toggle on 'wikitext highlighting' which uses different colours to help differentiate article text from wikitext.
Then type away, and press "Save" when finished! (You can also preview your changes before saving if you like.)
 
The VisualEditor option is intended as a user-friendly, "What You See Is What You Get" ([[WYSIWYG]]) editing aid, allowing one to edit pages without the need to learn wikitext markup. It is available only to registered, logged-in users through an opt-in choice available through [[Special:Preferences#mw-prefsection-betafeatures|personal preferences]]. See the [[Wikipedia:VisualEditor/User guide|VisualEditor user guide]] for more information.
It is often more convenient to copy and paste the text first into your
favorite text editor, edit and spell check there, and then paste back
into the browser to preview. This way, you can also keep a local copy of the
pages you authored so that you can make changes offline and for backup purposes.
 
<gallery mode="packed" class="center" heights="233" style="font-size:95%" caption="Two editing environments: wikitext and VisualEditor">
In the left column of the table below, you can see what effects are possible. In the right column, you can see how those effects were achieved. In other words, to make text look like it looks in the left column, type it in the format you see in the right column.

The Wikipedia community has developed [[Wikipedia:Manual of Style|style guidelines]] to make articles and facts appear in a standardized form, and Wikipedia easier to use as a whole. A basic list of [[Help:Wikitext|wikitext]] can be found on the [[Help:Cheatsheet|cheatsheet]]. An "[[Help:Edit toolbar|edit toolbar]]" is provided just above the edit box (pictured below), which allows logged-in users (by selecting the option in [[Special:Preferences#mw-prefsection-gadgets|personal preferences]]) to automatically place and format various aspects of wiki code. See [[Help:Wikitext]] for more information, remember that you can't break Wikipedia, and, although there are many protocols, [[Wikipedia:Editing policy#Wikipedia is a work in progress: perfection is not required|perfection is not required]], as [[Wikipedia:Wikipedia is a work in progress|Wikipedia is a work in progress]].
You may want to keep this page open in a separate browser window for reference. If you want to try out things without danger of doing any harm, you can do so in the SandBox.
 
[[File:WikiEditor-advanced menu-en.png|center]]
 
When you have finished editing, you should write a short [[Help:Edit summary|edit summary]] in the small field below the edit box (pictured below). You may use shorthand to describe your changes, as described in the [[Wikipedia:Edit summary legend|legend]]. To see how the page looks with your edits, press the "'''Show preview'''" button. To see the differences between the page with your edits and the previous version of the page, press the "'''Show changes'''" button. If you're satisfied with what you see, '''[[Wikipedia:Be bold|be bold]]''' and press the "'''Publish changes'''" button. Your changes will immediately be visible to all Wikipedia users.
<h2>Sections, Paragraphs, Lists and Lines</h2>

==== Minor edits ====
<table border=1>
{{further|Help:Minor edit}}
[[File:Minor edit.png|thumb|upright|The "minor edit" checkbox (circled) in the wikitext editor]]
A check to the "minor edit" box signifies that only superficial differences exist between the version with your edit and the previous version: typo/grammar corrections, fixing a formatting problem, etc. A ''minor edit'' is a version that the editor believes requires no review and could never be the subject of a dispute. Marking a change as minor does not mean that the edit is unimportant.
 
The "minor edit" option is one of several [[Wikipedia:Why create an account?#New editing options|options]] available only to [[Help:Logging in|registered users]]. Editors are never required to use this button. When in doubt, consider your work to be a normal edit.

Start your sections with header lines:
 
==== NewMajor Sectionedits ====
{{further|Wikipedia:Editing policy#Talking and editing}}
All editors are encouraged to [[Wikipedia:Be bold|be bold]] when improving articles, but there are several things that a user can do to ensure that potentially disruptive edits are performed smoothly. Before engaging in a major edit, a user should consider discussing proposed changes on the article discussion/talk page. During the edit, if doing so over an extended period, the {{tlx|in use}} tag can reduce the likelihood of an [[Help:Edit conflict|edit conflict]]. Once the edit has been completed, the inclusion of an [[Help:Edit summary|edit summary]] will assist in documenting the changes. These steps will help all to ensure that major edits are well received by the Wikipedia community.
 
A major edit should be reviewed to confirm that it is consensual to all concerned editors. Therefore, any change that affects the ''meaning'' of an article is major (not minor), even if the edit is a single word.
==== Subsection ====</td>
 
There are no necessary terms to which you have to agree when doing major edits, but the preceding recommendations have become best practice. If you do it your own way, the likelihood of your edits being re-edited may be higher.
<td><pre>
 
When making particularly large or complex changes, you may want to copy the article to [[Special:MyPage/sandbox|your sandbox]], so you can make changes without being interrupted by other editors. It is also a good idea to publish changes frequently, so that a browser crash or electrical failure will not result in you losing all of your work.
 
=== Adding references ===

Generally, sources are added directly after the facts they support at the end of the sentence and after any punctuation. Wikipedia permits editors to use any citation system that allows the reader to understand where the information came from and strongly encourages the use of [[Wikipedia:Inline citation|inline citations]] to do so. Common methods of placing inline citations include [[Help:Footnotes|footnotes]], [[Help:Shortened footnotes|shortened footnotes]] and [[Wikipedia:Citing sources#Parenthetical referencing|parenthetical references]].
 
Inline citations are most commonly placed by inserting a reference between <code><nowiki><ref></nowiki></code> ... <code><nowiki></ref></nowiki></code> tags, directly in the text of an article. The reference is a footnote, appearing as an inline link (e.g. <small><sup><span style="color:#002BB8">[1][2]</span></sup></small>) to a particular item in a collated, numbered list of footnotes, found wherever a {{tl|reflist}} template or <code><nowiki><references /></nowiki></code> tag is present, usually in a section titled "References" or "Notes". If you are creating a new page or adding references to a page that didn't previously have any, don't forget to add a references section with this display markup.
==== Subsection ==== or <h4>Subsection</h4></pre></td>

There are a number of tools available to help with citation placement and formatting, some of which are internal tools and scripts, while others are available from external sites. For an example of the former, [[Wikipedia:RefToolbar|RefToolbar]] is a [[JavaScript]] toolbar displayed above the edit box that provides the ability to automatically fill out various [[Wikipedia:Citation templates|citation templates]] and insert them in the text already formatted inside <code><nowiki><ref></nowiki></code> ... <code><nowiki></ref></nowiki></code> tags. For an example of the latter, the [https://citer.toolforge.org/ Citer] converts a [[digital object identifier]] (DOI) or [[Google Books]] address (URL) into a filled-out {{tl|cite journal}} or {{tl|cite book}} template ready to be pasted into an article. See [[Help:Citation tools]] for many others.

{{hatnote|Introductions: [[Help:Introduction to images with Wiki Markup/1]] and [[Help:Introduction to images with VisualEditor/1]]}}
A file that is already hosted on Wikipedia or the [[Wikimedia Commons]] can be inserted with the basic code <code><nowiki>[[File:FILENAME|thumb|DESCRIPTION]]</nowiki></code>. (<code>Image:</code> can be substituted for <code>File:</code> with no change in effect; the choice between the two is purely a matter of editorial preference.) Using <code>thumb</code> generates a [[thumbnail]] of an image (the most common placement option), which is typically sized differently from the original image. The Wikimedia Commons' [[Commons:Special:UploadWizard|File Upload Wizard]] and Wikipedia's [[Wikipedia:File Upload Wizard|File Upload Wizard]] will guide you through the process of submitting media. There are various file formats available.

Before [[Help:Your first article|starting a new article]], please understand [[Wikipedia:Notability|Wikipedia's notability requirements]]. In short, the topic of an article must have already been the subject of publication in [[Wikipedia:Reliable sources|reliable sources]], such as books published by major publishing houses, newspapers, magazines, peer-reviewed scholarly journals and websites that meet the same requirements as reputable print-based sources. Information on Wikipedia must be verifiable; if no reliable [[Wikipedia:Independent sources|third-party]] sources can be found on a topic, then it should not have a separate article. Wikipedia's concept of notability applies this basic standard to avoid [[Wikipedia:What Wikipedia is not#Wikipedia is not an indiscriminate collection of information|indiscriminate]] inclusion of topics.
 
An [[Wikipedia:Article wizard|Article Wizard]] is available to help you create articles — it is not required but will help you construct better articles. '''Note:''' The ability to create articles directly in mainspace [[Wikipedia:Autoconfirmed article creation trial/Request for comment on permanent implementation|is restricted]] to autoconfirmed users, though non-confirmed users and non-registered users can submit a proposed article through the [[Wikipedia:Articles for creation|Articles for Creation]] process, where it will be reviewed and considered for publication. Before creating an article, please [[Help:Searching|search]] Wikipedia first to make sure that an article does not already exist on the subject, and please also review the [[Wikipedia:Article titles|article titling policy]] for guidance on what to name the article.

[[File:Editing basics - Talk pages.webm|thumb|upright|thumbtime=1|A screencast demonstrating how to use a talk page. <small>(2:43 min)</small>]]
Every article on Wikipedia has a [[Help:Talk pages|talk page]], reached by clicking the "Talk" tab just above the title (for example, [[Talk:Alexander the Great]]). There, editors can discuss improvements to the content of an article. If you ever make a change that gets [[Wikipedia:Reverting|reverted]] by another editor, discuss the change on the talk page! The [[Wikipedia:BOLD, revert, discuss cycle|BOLD, revert, discuss cycle]] is a popular method of reaching consensus. It is very important that you conduct yourself with [[Wikipedia:Civility|civility]] and [[Wikipedia:Assume good faith|assume good faith]] on the part of others. [[Wikipedia:Edit warring|Edit warring]] (repeatedly overriding or reimplementing contributions) is highly discouraged.
 
Most other [[Wikipedia:Namespace|types of pages]] on Wikipedia also have associated talk pages, including the [[Wikipedia:User pages|User page]] each editor is assigned once they sign up. When other editors need to contact you, they will usually do this by leaving a message on [[Special:MyTalk|your talk page]]. When someone has left you a message that way, you will see a notice the next time you log in or view a page on Wikipedia.

If your table doesn't look right, make sure that all &lt;tr&gt; and &lt;td&gt; tags are closed with corresponding &lt;/tr&gt; and &lt;/td&gt; tags. It's best to start all lines belonging to a table in the first column as in the example above, or else you will get spurious space above the table or even a browser crash.
