Git Access

This project's Git repository can be checked out through anonymous (https) access with the following instructions:

git clone https://git.code.sf.net/p/drumkv1/code drumkv1-git

Hopefully, you'll be now with a proper source tree, ready for build.

Note

For quite some time there are alternate Git repositories which are kept in sync with the above sf.net one:

• https://github.com/rncbc/drumkv1.git
• https://gitlab.com/rncbc/drumkv1.git
• https://codeberg.org/rncbc/drumkv1.git

However, this doesn't mean that the drumkv1 project is about to migrate to a brand new hosting whatsoever: the original upstream source code repository is, will be, as it ever was, always kept somewhere else still in this world and universe.
