# Usage To use this plugin in your **`nmk`** project, insert this reference in your **nmk.yml** main file: ```yaml refs: - pip://nmk-proto!plugin.yml ``` Then add ***.proto** files in your project **protos** subfolder. \ Depending on other **`nmk`** plugins referenced in your project (e.g. **nmk-python**), code will be generated from these proto files.
