The Content-type Builder is only accessible to create and update content-types when your Strapi application is in a development environment, else it will be in a read-only mode in other environments.
Content-types are composed of one or several fields. Each field is designed to contain specific kind of data, filled up in the Content Manager (see Writing content).
In the Content-type Builder, fields can be added at the creation of a new content-type or component, or afterward when a content-type or component is edited or updated. The following documentation lists all existing regular fields but also tackles the specificities of custom fields, components, and dynamic zones. For each, you will find a definition, explanation of the form they take once in the Content Manager, and instructions to configure them.
✏️ NOTE
Depending on which content-type or component is being created or edited, not all fields — including components and dynamic zones — are always available.
The Text field displays a textbox that can contain small text. This field can be used for titles, descriptions, etc.

The Relation field allows to establish a relation with another content-type, that must be a collection type.
There are 6 different types of relations:
One way: Content-type A has one Content-type B
One-to-one: Content-type A has and belong to one Content-type B
One-to-many: Content-type A belongs to many Content-type B
Many-to-one: Content-type B has many Content-type A
Many-to-many: Content-type A has and belongs to many Content-type B
Many way: Content-type A has many Content-type B
Configuring the base settings of the Relation field consists in choosing with which existing content-type the relation should be established and the kind of relation. The edition window of the Relation field displays 2 grey boxes, each representing one of the content-types in relation. Between the grey boxes are displayed all possible relation types.
Click on the 2nd grey box to define the content-type B. It must be an already created collection type.
Click on the icon representing the relation to establish between the content-types.
Choose the Field name of the content-type A, meaning the name that will be used for the field in the content-type A.
(optional if disabled by the relation type) Choose the Field name of the content-type B.

Custom fields are a way to extend Strapi’s capabilities by adding new types of fields to content-types or components. Once installed (see Marketplace documentation), custom fields are listed in the Custom tab when selecting a field for a content-type.
Each custom field type can have basic and advanced settings. The Marketplace(opens new window) lists available custom fields, and hosts dedicated documentation for each custom field, including specific settings.
Components are a combination of several fields. Components allow to create reusable sets of fields, that can be quickly added to content-types, dynamic zones but also nested into other components.
When configuring a component through the Content-type Builder, it is possible to either:
or use an existing one by clicking on Use an existing component.
