+## Cyclps Pack Tests
+
+[![Build Status](https://github.com/CyclopsMC/packtests/workflows/gametests/badge.svg)](https://github.com/CyclopsMC/CyclopsCore/actions?query=workflow%3Agametests)
+
+Repo for testing all Cyclops mods in a production client and server environment.
+
+
+### Motivation
+
+While mods are always tested in isolation within their own development environment,
+development environments can always differ a bit compared to production environments,
+especially when combined with other mods.
+
+As such, this repo aims to test real-world environments to ensure everything works as intended.
+
+### Modpacks
+
+This defines several modpacks (see `modpacks/`) for different mod loaders at different minecraft versions.
+These packs are defined in their own `pom.xml` file, which defines their precise version.
+Not all packs may be defined for all loaders and minecraft versions.
+
+- `cyclops-all`: All mods developed under the Cyclops organization.
+- `cyclops-all-deps`: All mods developed under the Cyclops organization, including their optional dependencies.
+- `cyclops-id`: All Integrated Dynamics-related mods developed under the Cyclops organization.
+
+### Testing
+
+All packs are started in both a client and server environment, using the [mc-runtime-test](https://github.com/headlesshq/mc-runtime-test) and [mc-server-test](https://github.com/headlesshq/mc-server-test) GitHub actions.
+Additionally, [game tests](https://minecraft.wiki/w/GameTest) are executed.
+
+### Automatic dependency updates
+
+Using [Renovate](https://www.mend.io/renovate/), versions of all mods are always automatically updated to their latest version.
+This allows us to detect breaking changes immediately.
+
+### Modpack downloads
+
+The mod jars of all modpacks are made available as downloads.
+To access these, you open [the latest workflow run](https://github.com/CyclopsMC/packtests/actions/workflows/gametests.yml?query=branch%3Amaster),
+and download the artifact you are interested in (e.g. `cyclops-all-1.21.1-neoforge-mods`).
