# rippled Source
|
|
|
|
Some of these directories come from entire outside repositories brought in
|
|
using [git-subtree][]. This means that the source files are inserted directly
|
|
into the `rippled` repository. They can be edited and committed just as if they
|
|
were normal files.
|
|
[git-subtree]: https://github.com/apenwarr/git-subtree
|
|
|
|
If you create a commit that contains files both from a subtree, and from the
|
|
`rippled` source tree, please use care when designing the commit message, since
|
|
it will appear in the subtree's individual repository when the changes are
|
|
pushed back to the upstream. Better yet, do not mix files from subtrees and
|
|
`ripple` in the same commit at all.
