+# Caching
+
+Some of the [built-in plugins] implement intelligent caching mechanisms, which
+massively speed up consecutive builds by reducing the amount of work that needs
+to be done. This guide explains how to configure caching in different
+environments.
+
+## Prerequisites
+
+Caching is entirely optional but enabled by default. It can be disabled per
+plugin. If not configured otherwise, plugins will cache their data in the
+`.cache` folder in the root of your project. For this reason it's recommended
+to create a `.gitignore` file in the root of your project:
+
+``` title=".gitignore"
+.cache
+```
+
+This ensures that cached files are not added to your git repository – something
+that is generally not recommended to do unless absolutely necessary. In some
+cases, you might need to check in cached files, e.g. when you need to
+pre-generate [social cards] locally, e.g., when you're not be able to install
+the image processing dependencies in your continuous integration (CI)
+environment.
+
+In this case, we recommend changing the `cache_dir` setting – something that all
+plugins that implement caching share – to a folder which you add to your git
+repository.
+
+  [built-in plugins]: ../index.md
+  [social cards]: ../../setup/setting-up-social-cards.md
