+# General Docker requirements
+
+## Overview
+
+Testcontainers requires a Docker-API compatible container runtime. 
+During development, Testcontainers is actively tested against recent versions of Docker on Linux, as well as against Docker Desktop on Mac and Windows. 
+These Docker environments are automatically detected and used by Testcontainers without any additional configuration being necessary.
+
+It is possible to configure Testcontainers to work for other Docker setups, such as a remote Docker host or Docker alternatives. 
+However, these are not actively tested in the main development workflow, so not all Testcontainers features might be available and additional manual configuration might be necessary. 
+If you have further questions about configuration details for your setup or whether it supports running Testcontainers-based tests, 
+please contact the Testcontainers team and other users from the Testcontainers community on [Slack](https://slack.testcontainers.org/).
