+### `links`
+
+The `links` parameter allows you to define links associated with a dimension.
+They can be rendered as HTML links by supporting tools, e.g., [Workbooks][ref-workbooks].
+
+Links are useful to let users navigate to related external resources (e.g., Google
+search), internal tools (e.g., Salesforce), or other pages in a BI tool.
+
+Each link must have a `name`, a `label`, and a `url`. The `name` is used as an identifier
+in the [synthetic dimension](#synthetic) name. The `url` is a SQL expression that constructs
+the link URL. It can [reference][ref-references] column and dimension values, just like
+the [`sql` parameter](#sql) or [`mask` parameter](#mask).
+
+Optionally, a link might use the `icon` parameter to reference an icon from a [supported
+icon set][link-tabler] to be displayed alongside the link label.
+
+Optionally, a link might use the `target` parameter to specify [where to open it][link-target]:
+`blank` (default) to open in a new tab/window or `self` to open in the same tab/window.
+
+```yaml
+cubes:
+  - name: users
+
+    dimensions:
+      # Definitions of dimensions such as `email`, etc.
+
+      - name: full_name
+        sql: full_name
+        type: string
+        links:
+          - name: google_search
+            label: Search on Google
+            url: "CONCAT('https://www.google.com/search?q=', {CUBE}.full_name)"
+            icon: brand-google
+            target: blank
+
+          - name: salesforce_search
+            label: Search in Salesforce
+            url: "CONCAT('https://your-company.salesforce.com/search/results/?q=', {email})"
+            target: blank
+
+          - name: send_email
+            label: Write an email
+            url: "CONCAT('mailto:', {email})"
+            icon: send
+```
+
+#### `params`
+
+The optional `params` parameter can be used to add additional query parameters to the
+URL. It accepts a map of key-value pairs, where keys are parameter names and values are
+parameter values.
+
+Values in `params` can [reference][ref-references] columns and dimension values.
+Additionally, values in `params` can reference filters applied to the current query using
+the [`FILTER_PARAMS` context variable][ref-filter-params].
+
+Conveniently, the `propagate_filters_to_params` parameter, `true` by default, can be used
+to pass all filters from the current query as an additional parameter. Filters will use
+the same format as the [`filters` query parameter][ref-rest-filters] in the REST API.
+The `param_name_for_filters` parameter, `filters` by default, can be used to customize
+the name of this additional parameter.
+
+All parameter keys and values will be [URL-encoded][link-encode-uri-component]
+when the full URL is constructed.
+
+```yaml
+cubes:
+  - name: users
+
+    dimensions:
+      # Definitions of dimensions such as `id`, `country`, etc.

+      - name: full_name

+            # Pass all filters from the current query as the `my_precious_filters` query parameter
+            param_name_for_filters: my_precious_filters
+```
+
+#### Dimensions
+
+Each link will be rendered as an additional [synthetic](#synthetic) dimension in the
+result set, with the following naming convention:
+
+- `<dimension_name>___link_<link_name>_url`
+
+<Info>
+
+All references in link URLs and parameters must resolve to a single value for a given
+value of the dimension on which the link is defined. Otherwise, it will result in
+duplicate rows in the result set.

 ### `meta`
 
-Custom metadata. Can be used to pass any information to the frontend.
+The `meta` parameter allows you to attach arbitrary information to a dimension.
