+; You can setup `custom_nanopb_protos` `nanopb_options` vars to generate code from proto files
+;
+; Generator will use next folders:
+;
+;   `$BUILD_DIR/nanopb/generated-src` - `*.pb.h` and `*.pb.c` files
+;   `$BUILD_DIR/nanopb/md5` - MD5 files to track changes in source .proto/.options
+;
+; Compiled `.pb.o` files will be located under `$BUILD_DIR/nanopb/generated-build`
+;
+; Example:
+
+[env:pio_with_options]
+platform = native
+lib_deps = Nanopb
+
+src_filter =
+    +<pio_with_options.c>
+
