 ## Rules for writing a query-type template variable [#query-variable-rules]
 
-As discussed in the [section on defining template variables](#step1), there are three variable types: query, list, and text field. The query-type variable is the most complex to create because you must create a working query that returns values, which are then used to populate the dropdown in the template variable bar at the top of the dashboard. 
+As discussed in the [section on defining template variables](#step1), there are three variable types: query, list, and text field. The query-type variable is the most complex to create because you must create a working query that returns **a list of values**, which are then used to populate the dropdown in the template variable bar at the top of the dashboard.

 Note that this is a different topic than writing queries that make use of a template variable.

 Here are some rules and guidance on creating a query-type variable:
-* Queries must use the `uniques` or `keyset` syntax. 
-* The same syntax and limits of both functions are applicable here. Examples:
-
-  ```sql
-  From PageAction select uniques(countryCode)  --> this will return up to 1k results
-  ```
-
-  ```sql
-  From PageAction select uniques(countryCode, 10000) --> this will return up to 10k results
-  ```
+* You can use almost any NRQL query as long as it returns a list of values. For that, you can use either the `uniques` or `keyset` functions:
+  * with `uniques`:
+    ```sql
+    From PageAction select uniques(countryCode)
+    ```
+    ```sql
+    -- you can use the second param to define the maximum number of results to be listed.
+    From PageAction select uniques(countryCode, 10000) --> this will return up to 10k results
+    ```
+    Reference docs: [`uniques`](/docs/nrql/nrql-syntax-clauses-functions/#func-uniques) 
+  * with `keyset`
+    ```sql
+    --- with `keyset`, you'll get a list with all of the attributes from the table you're querying from
+    From PageAction select keyset() SINCE 1 day ago  
+    ```
+    Reference docs: [`keyset`](/docs/nrql/nrql-syntax-clauses-functions/#keyset)
 
-  ```sql
-  From PageView select keyset() SINCE 1 day ago
-  ```
-Please, check [`uniques`](/docs/nrql/nrql-syntax-clauses-functions/#func-uniques) and the [`keyset`](/docs/nrql/nrql-syntax-clauses-functions/#keyset) for more info.
-
-* You can use almost any NRQL query as long as the `uniques` and `keyset` components return a list of values.
 * Nested variables are not supported: there can't be variables within variables.
