+# C/C++ very basic support for IntelliJ IDEA CE
+
+... or how to make an IJ IDEA a little VSCode...
+
+## Includes
+- making new C or C++ file (e.g., in empty project)
+- syntax highlighting is actually provided by IJ itself;
+- refactoring, code analysis, advanced types of highlighting is provided with Language Server Protocol via lsp4ij plugin from Redhat.
+
+## Not (yet) implemented
+- CMake, make, ninja any project build support (just use Terminal...);
+- STM32 (or any other embedded C) projects
+- choosing various language standards for Clangd
+- any additional checks except the clangd provides by default;
+
+## Additional requirements
+- clangd visible through PATH
+- clang/clang++ for compiling projects manually
+
+## How to start
+
+Install plugin >> Restart IDE
+
+Empty project >> New file >> New C (or C++) file
+
+Enjoy!
