 ## Introduction
 
-The model <Term id="materialization">materializations</Term> you're familiar with, `table`, `view`, and `incremental` are implemented as macros in a package that's distributed along with dbt. You can check out the [source code for these materializations](https://github.com/dbt-labs/dbt-core/tree/main/core/dbt/include/global_project/macros/materializations). If you need to create your own materializations, reading these files is a good place to start. Continue reading below for a deep-dive into dbt materializations.

 It's possible to implement your own snapshot strategy by adding a macro with the same naming pattern to your project. For example, you might choose to create a strategy which records hard deletes, named `timestamp_with_deletes`.

 The rendering context for the `where` config is the same as for all configurations defined in `.yml` files. You have access to `{{ var() }}` and `{{ env_var() }}`, but you **do not** have access to custom macros for setting this config. If you do want to use custom macros to template out the `where` filter for certain tests, there is a workaround.
