[edit] Submitting Patches

Please review Submitting code to OpenSim

[edit] Feature Proposals

Larger changes may require feature proposals depending on whether they introduce or significantly change existing functionality. Please use your judgement to determine whether this is required.

For more details please see the Feature Proposals page.

[edit] Developer Documentation

Please be aware that some of this documentation may be out of date. If this appears to be the case then please ask for more information on the mailing lists or IRC channels (details are on the Main Page). If you can't find what you want here you might want to try looking in the User Documentation.
