 Given a predicate, filter out all elements that don't satisfy that predicate.
 May also be used to filter based on an inequality with a given value based
 on the comparison ordering of the element.
 
 ## Examples
-See [BEAM-7389](https://issues.apache.org/jira/browse/BEAM-7389) for updates.

+### Function
+
+`Filter` accepts a function that receives the element as the first argument,
+and returns `True` if the element will be kept, or `False` if the element will 
be filtered out.
+
+```py
+{% github_sample 
/apache/beam/blob/master/sdks/python/apache_beam/examples/snippets/transforms/element_wise/filter.py
 tag:filter_function %}```
+
+<table>
+  <td>
+    <a class="button" target="_blank"
+        
href="https://github.com/apache/beam/blob/master/sdks/python/apache_beam/examples/snippets/transforms/element_wise/filter.py";>
+      <img src="https://www.tensorflow.org/images/GitHub-Mark-32px.png";
+        width="20px" height="20px" alt="View on GitHub" />
+      View on GitHub
+    </a>
+  </td>
+</table>
+<br>
+
+### Lambda
+
+Lambda functions can also be used.
+
+```py
+{% github_sample 
/apache/beam/blob/master/sdks/python/apache_beam/examples/snippets/transforms/element_wise/filter.py
 tag:filter_lambda %}```
+
+<table>
+  <td>
+    <a class="button" target="_blank"
+        
href="https://github.com/apache/beam/blob/master/sdks/python/apache_beam/examples/snippets/transforms/element_wise/filter.py";>
+      <img src="https://www.tensorflow.org/images/GitHub-Mark-32px.png";
+        width="20px" height="20px" alt="View on GitHub" />
+      View on GitHub
+    </a>
+  </td>
+</table>
+<br>
+
+### Multiple Arguments
+
+Multiple function arguments can be passed as additional arguments to `Filter`.
+They will be passed as additional positional arguments or keyword arguments to 
the function.
+
+```py
+{% github_sample 
/apache/beam/blob/master/sdks/python/apache_beam/examples/snippets/transforms/element_wise/filter.py
 tag:filter_multiple_arguments %}```
+
+<table>
+  <td>
+    <a class="button" target="_blank"
+        
href="https://github.com/apache/beam/blob/master/sdks/python/apache_beam/examples/snippets/transforms/element_wise/filter.py";>
+      <img src="https://www.tensorflow.org/images/GitHub-Mark-32px.png";
+        width="20px" height="20px" alt="View on GitHub" />
+      View on GitHub
+    </a>
+  </td>
+</table>
+<br>
+
+### Side Inputs - Singleton
+
+If there is a single value in the `PCollection`, such as the average from 
another computation,
 
 Review comment:
   Do you mean "If there is a single value in the `PCollection`"->"If the 
`PCollection` has a single value" ? Change the phrasing to clarify.
