You might want to learn simply [[wikipedia:How to start a page|how to start a page]], you might want informal tips on [[wikipedia:Contributing to Wikipedia|contributing to Wikipedia]], or even the full kaboodle of [[Wikipedia:Utilities|utilities]] for editors. If you want the technical details about how to edit a Wikipedia page, though, you've come to the right place.
<!-- Please note that this is NOT the place to practice editing pages! Instead, please use Wikipedia's sandbox: click in the Search bar at the top of the page, type "Wikipedia:Sandbox" (without the quotes) and press the Return or Enter key on your keyboard. -->

[[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 "Talk page" link and then on "Edit this page" 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 that can be made in [[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 backup copy of the
pages you authored so that you can make changes offline.
 
<gallery mode="packed" class="center" heights="140" style="font-size:95%" caption="Two editing environments: Source Editor (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]] because [[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 [[wikipedia:Sandbox|Sandbox]].
 
[[File:WikiEditor-advanced menu-en.png|center]]<br>
== Sections, Paragraphs, Lists and Lines ==
 
When you have finished editing, you should write a short [[Help:Edit summary|edit summary]] in the field underneath those words (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 click on the "'''Publish changes'''" button. Your changes will immediately be visible to all Wikipedia users.

[[File:Minor edit.png|thumb|upright|The "minor edit" checkbox (circled) in the wikitext editor]]
==== Sub-subsection ====
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.

=== Subsection ===
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.
==== Sub-subsection ====

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.
<tr>

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.

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 the loss of all your work.

** they look clean
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]].
** Note that the symbol must be the first character on a new line.
</td>
<td><pre><nowiki>* Lists are good:

</td>
</tr>
 
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.

There are a number of tools available to help with citation placement and formatting, some of which are internal tools and scripts, whereas 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.

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.

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. Do not indent lines, and do not include empty lines within a table. Otherwise, you will get spurious space above the table or even a browser crash.
 
Here's a more advanced example, showing some more options available for making up tables. You can play with these settings in your own table to see what effect they have. Keep in mind that though colors are possible, it's best to use them sparingly. Check the above tables to see what can be done to the text inside the cells.
