+## Generate compilation database
 
-You could use the following commands to generate the `compile_commands.json` file:
+[JSON Compilation Database](https://clang.llvm.org/docs/JSONCompilationDatabase.html) files can be used by [clangd](https://clangd.llvm.org/) or similar tools to add source code cross-references and code completion functionality to editors.
+
+The following command can be used to generate the `compile_commands.json` file:
 
 ```
-BAZEL_BUILD_OPTION_LIST="--define=engine=multi" ./tools/gen_compdb.py --include_all //test/... //:lib
+BAZEL_BUILD_OPTION_LIST="--define=engine=multi" ./tools/gen_compilation_database.py --include_all //test/... //:lib
 ```
 
-Then you could use clangd (or other tools the could parse `compile_commands.json`) to setup editors with cross reference, code completion.
