-## Contributing

-Rules for creating a new example:
-
-- Makefile golden reference for desktop/server example: [http-server](http-server)
-- Makefile golden reference for the embedded example:
-   [stm32/nucleo-f746zg-baremetal](stm32/nucleo-f746zg-baremetal)
-- An example must build on Windows, Mac and Ubuntu Linux systems
-- Assume that user installed tools according to https://mongoose.ws/tutorials/tools/
-- Makefile must not include any other make files
-- Use `CFLAGS` for system-specific compilation options
-- Use `CFLAGS_MONGOOSE` for mongoose-specific compilation options
-- Use `$(CFLAGS) $(CFLAGS_MONGOOSE) $(CFLAGS_EXTRA)` to compile
-- If external repository is required, download it on demand using git
-  shallow clone. See embedded example golden reference
-- Keep Makefile as short as possible, but verbose to understand it easily
-- Symlink files when required, like `mongoose.c`, `ca.pem`, etc. Make no copies
-- Example's README.md should contain only the title and the link to mongoose.ws

-# Mongoose as a MicroPython user module
-
-The most basic usage is in `main.py`.
-
-You'll have to configure Mongoose for your desired platform, this example runs on the `unix` port and Mongoose detects it as a known architecture and hence configures itself to use sockets and time base. For other platforms, you'll have to do your homework (there's plenty of Mongoose examples for several platforms); also check respective MicroPython build instructions.
-
-Check [_thread](https://docs.micropython.org/en/latest/library/_thread.html) support for more advanced usage
