+My Build is Using Too Many Resources
+====================================
+
+We limit build resources to make sure that users don't overwhelm our build systems.
+If you are running into this issue,
+there are a couple fixes that you might try.
+
+.. note:: The current build limits can be found on our :doc:`/builds` page.
+
+Reduce formats you're building
+------------------------------
+
+You can change the formats of docs that you're building with our YAML file's :ref:`yaml-config:Formats` option.
+
+In particular, the `htmlzip` takes up a decent amount of memory and time,
+so disabling that format might solve your problem.
+
+Reduce documentation build dependencies
+---------------------------------------
+
+A lot of projects reuse their requirements file for their documentation builds.
+If there are extra packages that you don't need for building docs,
+you can create a custom requirements file just for documentation.
+This should speed up your documentation builds,
+as well as reduce your memory footprint.
