Wikivoyage:How to edit a page
You can modify the page however you want, but anything you add must be compatible with Wikivoyage copyleft. It helps the rest of us if you follow our policies and guidelines and manual of style, but don't let that stop you from plunging forward. It's more important that you add something than that you do it perfectly.
Previewing and saving a page
To see what your changes will look like, hit the Show preview button, which will not save the page. Do a preview just before saving the page, to make sure your changes look right. When you're happy with the changes, hit the Save page button to save the page.
You can cancel your edits by clicking the Cancel link and of course Editing help brings you here.
Beneath the article editing text box is a short field labelled Summary. This is for putting a short note (edit summary) about what you've done to an article, such as "added Ao Shai To hotel details" or "spelling 'miserible' -> 'miserable'" or "took out obsolete detour directions to Spanish Steps". It can be helpful for people who are looking at the Recent changes or Page history pages to quickly see what you did.
If you've edited a page but it doesn't seem to have changed you should probably look at Special:Recentchanges or the article's history, since it is likely that someone has done a rollback of your change, and may have given an informative reason.
Using the check boxes
If you are logged in to a user account there will be a This is a minor edit checkbox for marking your changes as "minor". The idea with this is that people reviewing page history or recent changes can filter out unimportant changes. It's up to you to determine what makes your changes "minor" -- usually, spelling corrections, grammar, or formatting changes are "minor", and changes to the real information on a page are not.
The Watch this article checkbox puts this article on your watchlist. Any changes to the article, or to the article's talk page, by you or anyone else will show up in your watchlist, so you can keep an eye on the article.
The default setting — whether these checkboxes are checked or not by default — can be set in your user preferences.
Starting new pages
If you are starting a new page from the beginning, please make use of our article templates which helps to organize the information on a page and give a consistent look. See How to start a new page for more information.
Restoring previous article versions
If an editor changes or removes content from an article the old versions of the article are still available from the article's history. To view article history, click on the "history" tab for any article, then click on the date for the revision that you are interested in. To revert the article to the specified revision, simply click on the "edit" tab while viewing the old version and then re-save the version. Alternately, if you just want to revert a single edit, click on the "undo" link from an article's history next to the edit that is being reverted.
