 Use presets to:
 
 - Set up the bot with good default settings
-- Reduce duplication of your configuration
+- Avoid duplicating your configuration
 - Share your configuration with others
-- Use somebody else's configuration and extend it with your own rules
+- Use somebody else's configuration as-is, or extend it with your own rules
 
 ## How to use presets
 
-Let's say you're using the `config:recommended` preset, and want to pin your GitHub Action digests.
-Instead of writing your own Renovate config, you search through Renovate's built-in presets.
-You find the the `helpers:pinGitHubActionDigests` preset and add it to the `extends` array:
+Say you're using the `config:recommended` preset, and want to pin your GitHub Action digests.
+Instead of writing your own Renovate config, you search the docs, and find the `helpers:pinGitHubActionDigests` preset.
+Then you add the preset to the `"extends"` array in your Renovate configuration file:
 
 ```json
 {
   "extends": ["config:recommended", "helpers:pinGitHubActionDigests"]
 }
 ```
 
-Renovate now follows the rules for `config:recommended` plus the rules for `helpers:pinGitHubActionDigests`.
-If there is a logical conflict between presets, then the last preset in the array wins.
+In the example above, Renovate follows the rules from the `config:recommended` preset, plus the rules for `helpers:pinGitHubActionDigests`.

+!!! tip
+    If there is a logical conflict between presets, then the _last_ preset in the `"extends"` array "wins".
 
 ## Managing config for many repositories
 
-If you manage Renovate for many repositories, then you should create a global preset configuration.
-Then you extend the global preset in each repository.
-This way you have all global configuration in a single file, in a single repository.
+If you manage the Renovate configuration for many repositories, we recommend that you:
+
+1. Create a global preset configuration
+1. Extend from the global preset in all of the repositories that should use your global preset as base
+
+This way, when you want to change your global Renovate configuration, you only need to edit the global preset file.
 
 ## Presets are modular
 
-Preset configs are modular, they can be as small as a single package rule or as large as an entire configuration.
-This is similar to the way you can share ESLint configurations.
+Preset configs are modular: a preset can be as small or large as you need.
+A preset can even extend from _other_ presets.
 
 ## Built-in presets
 
-Renovate comes with a lot of built-in presets that you can use.
-Browse [Renovate's default presets](../presets-default.md) to find any that are useful to you.
-Once you find a preset you like, put it in an `extends` array in your config file.
+Renovate comes with many built-in presets.
+We recommend you browse [Renovate's default presets](../presets-default.md).
+Again, to use the preset: add it to the `"extends"` array in your Renovate config file.
 
 ### Contributing a new built-in preset
 
 If you have a Renovate config that may help others, you can put it into Renovate's built-in presets.

 Read [Contributing to presets](../config-presets.md#contributing-to-presets) to learn how.
 
 ## Summary
 
 In short:
 
-- Browse [Renovate's default presets](../presets-default.md) to find any that are useful to you
-- Publish your own if you wish to reuse them across repositories
+- Browse [Renovate's default presets](../presets-default.md), or our other presets, to find helpful presets
+- Use presets by putting them in the `"extends"` array in your Renovate config file
+- To manage the Renovate configuration for many repositories at once, create a global preset config file
+- The order of presets matters: in a logical conflict, the last preset in the `"extends"` array "wins"
