 A set of common utilities to use as libraries.
+
+## Usage
+
+The libraries are hosted on Maven Central, which means they can be added through the `dev.yumi.commons:yumi-commons` Maven coordinates.
+
+Specific modules can be found as `dev.yumi.commons:yumi-commons-<library>`.
+
+### Gradle
+
+Via a `libs.versions.toml` file:
+
+```toml
+[versions]
+yumi-commons = "<version>"
+
+[libraries]
+yumi-commons = { module = "dev.yumi.commons:yumi-commons", version.ref = "yumi-commons" }
+yumi-commons-core = { module = "dev.yumi.commons:yumi-commons-core", version.ref = "yumi-commons" }
+yumi-commons-collections = { module = "dev.yumi.commons:yumi-commons-collections", version.ref = "yumi-commons" }
+yumi-commons-event = { module = "dev.yumi.commons:yumi-commons-event", version.ref = "yumi-commons" }
+```
+
+Then in the Gradle buildscript:
+
+```kotlin
+dependencies {
+	implementation(libs.yumi.commons) // If using the whole bundle
+
+	implementations(libs.yumi.commons.core)
+	implementations(libs.yumi.commons.collections)
+	implementations(libs.yumi.commons.event)
+}
+```
