-got_request_exception is a callable within the flask.signals module of the Flask project.
+[got_request_exception](https://github.com/pallets/flask/blob/master/src/flask/signals.py)
+is a signal defined in the [Flask](/flask.html) project's
+`flask.signals` module that interrupts the WSGI flow when there is an
+issue with the HTTP request. It can also be thrown by your own
+view functions if there is an error and you want to raise it via a signal.

-Namespace is a class within the flask.signals module of the Flask project.
+[Namespace](https://github.com/pallets/flask/blob/master/src/flask/signals.py)
+is a class used within the `flask.signals` module, but it is
+actually imported from the
+[Blinker project](https://github.com/jek/blinker). Blinker
+is a fast dispatching system for event subscriptions, also known as
+"signals". [Flask](/flask.html) uses this library instead of
+implementing its own event subscription signaling model.
+[Namespace is defined within Blinker](https://github.com/jek/blinker/blob/master/blinker/base.py)
+as a mapping of signal names to signals, and it serves the
+same purpose in the Flask project.

-render_template is a callable within the flask.templating module of the Flask project.
+[render_template](https://github.com/pallets/flask/blob/master/src/flask/templating.py)
+is a [Flask](/flask.html) function from the `flask.templating` package.
+`render_template` is used to generate output from a
+[template file based on the Jinja2 engine](/template-engines.html)
+that is found in the application's templates folder.
+
+Note that `render_template` is typically imported directly from the `flask`
+package instead of from `flask.templating`. It is the same function that is
+imported, but there are less characters to type when you leave off
+the `.templating` part.
