+# Export Compile Commands - ECC
+Module implementing support for [JSON Compilation Database Format
+Specification](https://clang.llvm.org/docs/JSONCompilationDatabase.html).
+
+This is an alternative to
+[tarruda's](https://github.com/tarruda/premake-export-compile-commands) module,
+which does one simple thing - generates one `compile_commands.json` file for
+your project.
+
+Tested with clangd-13.
+
+## Requirements
+Premake 5.0.0 or later.
+
+## How to use
+Download premake-ecc and place it near your premake5.lua script. Then require it
+from your premake script
+
+```lua
+require "ecc/ecc"
+```
+
+After you simply can call:
+
+```
+premake5 ecc
+```
+
+Moldule will generate **one** `compile_commands.json` file near your main
+premake script. During generation it will use the default config (the first one
+you have specified in script). If you want to select specific config just pass
+it's name with command line option:
+
+```
+premake5 --config=release ecc
+```
+
+Careful! `config` option case sensitive! If there is no config passed via
+command line, module will choose the default one. 
+
+Note: if you want to embed this module into your premake build follow
+the [manual](https://premake.github.io/docs/Embedding-Modules/)
+
+## Future plans
+- Add unit tests
+
+## Alternatives
