 # :material-text-box: Fields
 
-Fields are additional types of metadata that you can attach to [file entries](./entries.md). Like [tags](tags.md), fields are not stored inside files themselves nor in sidecar files, but rather inside the respective TagStudio [library](./index.md) save file.
+Fields are extra pieces of information you can add to [file entries](./entries.md), similar to how [tags](tags.md) are added to entries. Fields are useful for storing information that doesn't nessisarily need to be a tag, such as titles, comments, notes, specific dates or times, etc.
 
-## Field Types
+To add a field to an entry, click the "Add Field" button in the preview panel. From there you can search and/or select a [field template](#field-templates) to choose from, or create a new one from the search bar. Alternatively you can create new field templates from **Edit -> Manage Field Templates**.
 
-### Text Line

-A string of text, displayed as a single line.
+## :material-text-box-plus-outline: Field Templates
 
-- e.g: Title, Author, Artist, URL, etc.
+Field templates are handy templates to use when adding fields to entries that contain preconfigured options but no actual data. When you add a field to an entry from the "Add Field" button, you choose from a template to add and then fill in the information afterwards. TagStudio includes a handful of field templates to start you off with, but you're free to modify or delete them, or simply create your own.
 
-### Text Box
+Field templates can be viewed, created, and deleted from the **Edit -> Manage Field Templates** window. You can also edit field templates from the "Add Field" menu, and create new ones on the fly from the search bar. Note that you can not currently delete field templates from the "Add Field" menu, just like tags.
 
-A long string of text displayed as a box of text.

-### Datetime
+## :material-format-list-bulleted-type: Field Types
 
-A date and time value.
+Fields come in a variety of types that are better suited for different types of information, and may provide additional options unique to those types. Single lines are good for fields like titles, while multiline blocks are good for things like comments and notes.
 
-- e.g: Date Published, Date Taken, etc.
+### :material-text-box: Text
+
+Text fields contain a piece of text with the option to display it either a single line or a multiline body of text.
+
+| Option    | Value      | Description                                                              |
+| --------- | ---------- | ------------------------------------------------------------------------ |
+| Multiline | True/False | Indicates if the text should be displayed on multiple lines or just one. |
