+## Applied Energistics 2 API
+
+The API for Applied Energistics 2. It is open source to discuss changes, improve documentation, and provide better add-on support in general.
+
+### Maven
+
+We use Github Packages as maven repository now. You can use the following snippet as example on how to add a repository to your gradle build file.
+
+    repositories {
+        maven {
+            name "AE2"
+            url "https://maven.pkg.github.com/AppliedEnergistics/Applied-Energistics-2"
+        }
+    }
+
+When compiling against the AE2 API you can use gradle dependencies, just add
+
+    dependencies {
+        compileOnly "appeng:appliedenergistics2:VERSION:api"
+    }
+
+or add the `compileOnly` line to your existing dependencies task to your build.gradle.
+
+Replace `VERSION` with the desired one. With 1.15+ we switched to using [semver](https://semver.org/). 
+It is highly recommended following its specification and further considering an upper bound for the dependency version.
+A change of the `MAJOR` version will be an API break and can lead to various crashes. Better to inform a player about the addon not supporting the new version until it could be tested or updated.
+
+An example string would be `appeng:appliedenergistics2:7.0.0-alpha.6:api` for the API only or `appeng:appliedenergistics2:7.0.0-alpha.6` for the whole mod.
+
+Builds obtained [here](https://github.com/AppliedEnergistics/Applied-Energistics-2/releases) or via [maven](https://github.com/AppliedEnergistics/Applied-Energistics-2/packages) should work in a development environment.
+However the dependency might need to be wrapped in `fg.deobf()` like `runtimeOnly fg.deobf("appeng:appliedenergistics2:VERSION:api")`
