 title: How to use custom activation strategies
 ---
 
+This guide takes you through how to use [custom activation strategies](../advanced/custom-activation-strategy.md) with Unleash. We'll go through how you define them in the admin UI and look at an implementation example in a [client SDK](../sdks/index.md).
+
 In this example we want to define an activation strategy offers a scheduled release of a feature toggle. This means that we want the feature toggle to be activated after a given date and time.

 We name our strategy `TimeStamp` and add one required parameter of type string, which we call `enableAfter`.

-After we have created the strategy definition, we can now decide to use that activation strategy for our feature toggle.

 All official client SDK's for Unleash provides abstractions for you to implement support for custom strategies.
