+## Opening Project in IDEs
+Comet is a multi-language project with native code written in Rust and JVM code written in Java and Scala.
+For Rust code, the CLion IDE is recommended. For JVM code, IntelliJ IDEA is recommended. 
+
+Before opening the project in an IDE, make sure to run `make` first to generate the necessary files for the IDEs. Currently, it's mostly about
+generating protobuf message classes for the JVM side. It's only required to run `make` once after cloning the repo.
+
+### IntelliJ IDEA
+First make sure to install the Scala plugin in IntelliJ IDEA. 
+After that, you can open the project in IntelliJ IDEA. The IDE should automatically detect the project structure and import as a Maven project.
+
+### CLion
+First make sure to install the Rust plugin in CLion or you can use the dedicated Rust IDE: RustRover.
+After that you can open the project in CLion. The IDE should automatically detect the project structure and import as a Cargo project.
+
+### Running Tests in IDEA
+Like other Maven projects, you can run tests in IntelliJ IDEA by right-clicking on the test class or test method and selecting "Run" or "Debug".
+However if the tests is related to the native side. Please make sure to run `make core`  or `cd core && cargo build` before running the tests in IDEA.
