This tutorial will show you how to import local and external files.

The compilation result will also contain contracts implemented in the imported files.

For a detailed explanation of the import keyword see the Solidity documentation

Other files in Remix can be imported just by specifying their path. Please use ./ for relative paths to increase portability.

It is possible to import files directly from GitHub with URLs like https://github.com/<owner>/<repo>/<path to the file>.

Files can be imported using all URLs supported by swarm. If you do not have a swarm node, swarm-gateways.net will be used instead.
