+## Building
+
+```sh
+$ make dependencies
+$ make
+```
+
+For development run:
+
+```sh
+$ make setup
+```
+
+which will create the `compile_commands.json` file for clangd.
+
+You can pass `R_HOME=...` to the make command to specify the R installation to use.
+It is not a bad idea to have a copy of the `../external/R` compiled for debugging.
+To do that you can use the `../../tools/build-gnur.sh` script with `-d` option.
