+## 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
+
+Our authoritative Maven repository is Github Packages, which you can also use in your builds. Use of Github Packages 
+[requires special setup](https://docs.github.com/en/packages/using-github-packages-with-your-projects-ecosystem/configuring-gradle-for-use-with-github-packages#authenticating-to-github-packages) 
+to authenticate with your personal access token.
+
+AE2 is also available without authentication from Modmaven. 
+
+You can use the following snippet as example on how to add a repository to your gradle build file.
+
+    repositories {
+        maven {
+            name "Modmaven"
+            url "https://modmaven.k-4u.nl/"
+            // For Gradle 5.1 and above, limit it to just AE2
+            content {
+                includeGroup 'appeng'
+            }
+        }
+        
+        // Required for libblockattributes
+        maven {
+            name = "BuildCraft"
+            url = "https://mod-buildcraft.com/maven"
+            content {
+                includeGroup "alexiil.mc.lib"
+            }
+        }
+    }
+
+When compiling against the AE2 API you can use gradle dependencies, just add
+
+    dependencies {
+        modCompileOnly "appeng:appliedenergistics2-fabric:VERSION:api"
+        
+        // Include only if you want AE2 at runtime
+        modRuntimeOnly "appeng:appliedenergistics2-fabric:VERSION"    
+    }
+
+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")`
+

-When compiling against the AE2 API you can use gradle dependencies, just add

-Where the __ are filled in with the correct version criteria; AE2 is available from the default forge maven so no additional repositories are necessary.

-An example string would be `appeng:appliedenergistics2:rv5-stable-1:api` for the API only or `appeng:appliedenergistics2:rv5-stable-1`  for the whole mod.
