+# Components Cleanup
+
+Managing state is challenging, especially in end-to-end testing, we use [ryuk](https://golang.testcontainers.org/features/garbage_collector/#ryuk) and following simple rules:
+- If `TESTCONTAINERS_RYUK_DISABLED=true`, no cleanup occurs — containers, volumes, and networks remain on your machine.
+
+  Feel free to use `ctf d rm` to remove containers when you are ready.
+- If `TESTCONTAINERS_RYUK_DISABLED` is unset, the test environment will be automatically cleaned up a few seconds after the test completes.
+
+
+Keep in mind that all components are mapped to [static ports](state.md), so without cleanup, only one environment can run at a time.
+
+This design choice simplifies debugging.
+
+A simplified command is available to prune unused volumes, containers, and build caches. Use it when you’re running low on space on your machine.
+```
+ctf d c
+```
+
+<div class="warning">
+
+The framework manages cleanup for both on-chain and off-chain Docker components. However, if your test involves actions like configuring Chainlink jobs, it's best practice to make these actions idempotent, so they can be applied reliably in any environment.

 # Intro
 
-The Chainlink Testing Framework (CTF) is a blockchain development framework written in Go. 
 
-Its primary purpose is to help Chainlink developers create extensive integration, e2e, performance, and chaos tests to ensure the stability of the Chainlink project.
 
-It can also be helpful to those who just want to use Chainlink oracles in their projects to help test their contracts, or even for those that aren't using Chainlink.
+The Chainlink Testing Framework is a toolset designed for end-to-end testing of Chainlink products, focusing on functionality, resiliency, and performance.
 
-This documentation is primarily for:
-- Engineers looking to write end-to-end tests
-- Non-technical users or external developers who want to [setup](framework/interactive.md) `Chainlink` nodes locally
+This documentation is intended for:
+- Chainlink engineers writing end-to-end tests in [Golang](https://go.dev/)
+- Engineers using other languages who want to integrate with the Chainlink platform
 
 To get started with writing tests, refer to the [Framework](./framework/getting_started.md) chapter, where we guide you from basic to more complex scenarios.
 
+If you want to build integration with Chainlink not in [Golang](https://go.dev/), please refer to our [Interactive](framework/interactive.md) chapter.
+
 [Repository](https://github.com/smartcontractkit/chainlink-testing-framework) contains two major pieces:
 - [Framework](framework/overview.md)
 - [Libraries](libraries.md)
-
-If you're a non-technical user or want to build integration with Chainlink not in `Golang`, please refer to our [Interactive](framework/interactive.md) chapter.
