+## DEPRECATION NOTICE
+This repository is no longer maintained. 
+This project contains the original source code of the intellij-hcl plugin. The code in this repository is kept static and can be used for historical reference only: no pull requests will be accepted.
+
+TL/DR. Starting from plugin version 0.7.0, the sources belong to JetBrains and the plugin is closed-source. You can download the new versions of the **free** plugin from JetBrains from the [JetBrains plugin repository](https://plugins.jetbrains.com/plugin/7808).
+
+### Note from Plugin Author
+
+I'd been developing this plugin for four years in my free time before last year, when it became obvious that due to lack of free time I could not keep up with the newest Terraform features.
+
+Meanwhile, IaaC and especially Terraform is becoming more and more popular, so I decided to transfer the plugin ownership to JetBrains. I believe that JetBrains has the resources to improve the plugin over time and provide efficient user support. To ensure that, as a JetBrains employee, I’ll be dedicating 20% of my work time to the plugin.
+
+I'd like to thank all users, contributors, people who spotted and reported bugs, and everyone who promoted the plugin all those years.
+
+As part of the transition, the source code was moved to the main IntelliJ repository which is private. The JetBrains plugin is  **[free](https://plugins.jetbrains.com/plugin/7808)**. The main plugin features will be compatible with JetBrains' free IDEs (\[IntelliJ IDEA, PyCharm\]x\[Community, Education\] Editions) as well as Google's Android Studio. Note that the main features include but are not limited to the features below.
