A section holds information added on the website. Each section represents a type of “thing” on the website. For example a news article would be a different section than a product. Dealer profiles, events and jobs are other examples of sections.
An entry is a single post on your website. For example, a single product, a single event, a single job page. An entry isn’t necessarily a page. For example you may have an entry for a dealer, but instead of having one dealer per page, the site shows all of the dealers on a single page.
Singles is a type of section that can only have one entry in it. They’re used for one-off pages - for example the home page. As there’s only one home page per site, it’s called a single.
A channel is a section that allows for multiple entries in it. A structure is a special kind of channel because it allows you to reorder the entries within it. For example you may wish to re-order products so your best sellers are at the top - so that would be a structure. But because a news section would be displayed in date order, we would use a standard channel instead.
An asset is simply a file. Normally images, but they may also be PDFs or Word Documents or anything else.
Most entries which allow to add assets to them have a limitation on the kind of asset you can upload. When adding a thumbnail to a product you can only add an image for example.
A field is an individual container for information. Entries are made up of one or more fields. For example an event may include the fields for a title, event information, a location and a date.
Fields with a language code next to its name (eg. "EN") are translatable.
Fields with a red * next to its name are required. When left empty, the entry will not be saved.
Means “Content Management System”. Craft is an example of a CMS.
A user is an individual account on the CMS. Most sites only have 1 account that can access the control panel, but more complex sites, such as this one, may have different access for different members of your team. This site also has public registrations that allows people to sign up, these become users without administration rights.
A slug is a combination of lower case words, numbers and dashes that every entry has. It's used to identify the entry and to create a clean URL.
For most entries, this needs to be unique (with some exceptions to categories). It looks likes this: xpedia-360-ex-1. The CMS will take care of the slugs automatically, but you can edit these to change translations or if you want the slug to be something else entirely. But most of the time, you don't need to edit these at all.
