+## [`org.spongepowered.gradle.ore`](https://plugins.gradle.org/plugin/org.spongepowered.gradle.ore)
+
+A plugin to deploy artifacts to the [Ore](https://ore.spongepowered.org) plugin repository.
+
+When using SpongeGradle, this plugin is auto-configured based on the plugin configuration used.
+
+Multiple publications are supported for situations where a project produces multiple artifacts.
+
+Full DSL:
+
+```kotlin
+oreDeployment {
+    oreEndpoint("https://ore.spongepowered.org/") // default
+    apiKey().set(
+        providers.gradleProperty("org.spongepowered.ore.apiToken")
+            .orElse(providers.environmentVariable("ORE_TOKEN"))
+    ) // default value
+
+    publications {
+        register("default") {
+            // Ore project ID, taken from the first plugin created by SpongeGradle when present
+            projectId.set("id")
+            createForumPost.set(true) // default
+            // Contents (aka release notes) for the version
+            versionBody.set("") // default (empty)
+            // Channel
+            channel.set("Release") // default
+            // Artifact -- must be a single file
+            publishArtifacts.from(tasks.jar.map { it.outputs }) // default when SpongeGradle is present
+        }
+    }
+    
+    // alternatively:
+    defaultPublication {
+        // same as above
+    }
+}
+```
+
+## [`org.spongepowered.gradle.repository`](https://plugins.gradle.org/plugin/org.spongepowered.gradle.repository)
+
+Provides a simple way to register Sponge's maven repository in a buildscript:
+
+```groovy
+plugins {
+    id 'org.spongepowered.gradle.repository' version '<version>'
+}
+
+repositories {
+    sponge.releases()
+    sponge.snapshots()
+}
+```
+
+This extension is applied to both the `settings` `dependencyResolutionManagement` repository section, as well as the buildscript `repositories` section.
+
+> **Note**
+> The Kotlin stub generation for `settings.gradle.kts` files does not generate stubs for the `dependencyResolutionManagement.repositories {}` block. The extension will have to be read manually, using something like:
+> ```kotlin
+> val sponge = (this as ExtensionAware).extensions.getByType(org.spongepowered.gradle.repository.SpongeRepositoryExtension::class)
+> ```
