+The essence of the UFM syntax is curly brackets with an alias prefix delimited with a colon.

-- The opening is `{` U+007B Left Curly Bracket
-- The closing is `}` U+007D Right Curly Bracket
-- The marker prefix can be any valid Unicode character(s), including emojis
+- The opening token is `{` U+007B Left Curly Bracket
+- The alias prefix can be any valid Unicode character(s), including emojis
+- Followed by `:` U+003A Colon, (not part of the alias prefix itself)

 The internal working of the `ufm-label-value` component would then be able to access the property's value using the [Context API](../extending/backoffice-setup/working-with-data/context-api).
 
-## Available UFM components
 
-As for Umbraco 14.1.0, the following UFM components are available to use.
+### Filters
 
-| Name        | Marker | Example syntax    | Renders component                    |
-| ----------- | ------ | ----------------- | ------------------------------------ |
-| Label Value | `=`    | `{=bodyText}`     | `<ufm-label-value alias="bodyText">` |
-| Localize    | `#`    | `{#general_name}` | `<umb-localize key="general_name">`  |
+In addition, a filter syntax can be applied to UFM contents. This can be useful for formatting or transforming a value without needing to develop your own custom UFM component.
+
+The syntax for UFM filters uses a pipe character `|` (U+007C Vertical Line). Multiple filters may be applied, and the value from the previous filter is passed onto the next.
+
+To display a rich text value, stripping out the HTML markup and limiting it to the first 15 words could use the following filters:
+
+```markdown
+{umbValue: bodyText | strip-html | word-limit:15}
+```
+
+The following UFM filters are available to use.
+
+| Name       | Alias        | Example syntax                         |
+| ---------- | ------------ | -------------------------------------- |
+| Lowercase  | `lowercase`  | `{umbValue: headline | lowercase}`     |
+| Strip HTML | `strip-html` | `{umbValue: bodyText | strip-html}`    |
+| Title Case | `title-case` | `{umbValue: headline | title-case}`    |
+| Truncate   | `truncate`   | `{umbValue: intro | truncate:30:...}`  |
+| Uppercase  | `uppercase`  | `{umbValue: headline | uppercase}`     |
+| Word Limit | `word-limit` | `{umbValue: intro | word-limit:15}`    |

+## UFM components
+
+### Available UFM components
+
+The following UFM components are available to use.
+
+- Label Value
+- Localize
+- Content Name
 
 More UFM components will be available in upcoming Umbraco releases.
 
+
+#### Label Value
+
+The Label Value component will render the current value of a given property alias.
+
+The alias prefix is `umbValue`. An example of the syntax is `{umbValue: bodyText}`, which would render the component as `<ufm-label-value alias="bodyText"></ufm-label-value>`.
+
+For brevity and backwards-compatibility, the `=` marker prefix can be used, e.g. `{=bodyText}`.
+
+
+#### Localize
+
+The Localize component will render a localization for a given term key.
+
+The alias prefix is `umbLocalize`. An example of the syntax is `{umbLocalize: general_name}`, which would render the component as `<ufm-localize alias="general_name"></ufm-localize>`.
+
+Similarly, for brevity and backwards-compatibility, the `#` marker prefix can be used, e.g. `{#general_name}`.
+
+
+#### Content Name
+
+The Content Name component will render the name of a content item, (either Document, Media or Member), from the value of a given property alias. Multiple values will render the names as a comma-separated list.
+
+The alias prefix is `umbContentName`  An example of the syntax is `{umbContentName: pickerAlias}`, which would render the component as `<ufm-content-name alias="pickerAlias"></ufm-content-name>`.
+
+As of Umbraco 15.0.0, the Content Name component supports the content-based pickers, e.g. Document Picker, Content Picker (formerly known as Multinode Treepicker) and Member Picker. Support for the advanced Media Picker will be available in upcoming Umbraco release.
