Suggesting documentation changes

The NEM Developer Center is an open source project and we love to receive contributions from our community — you! There are many ways to contribute, from writing guides, improving the documentation, submitting errors and requests or writing new pieces of documentation which can be incorporated into the docs itself.

Error reports

If you think you have found an error in the NEM Developer Center, first make sure that you are testing against the latest version of NEM Developer Center - your issue may already have been fixed. If not, search our issues list on GitHub in case a similar issue has already been opened.

It is very helpful if you can prepare a reproduction of the error. It makes it easier to find the problem and to fix it.

Please, take into consideration the next template to report your issue:

Error description

Short and expressive sentence explaining what is wrong.

Url or screenshot

For faster issue detection, we would need where to find it.

Provide as much information as you can.

Open a new issue here.


If you find yourself wishing for content that does not exist in the NEM Developer Center, you are probably not alone. Most of the documentation and guides that the NEM Developer Center has today have been added because our users saw the need. Open an issue on our issues list on GitHub which describes the missing documentation or improvement you would like to see.

If the improvement is not related to documentation, but with a specific project, please check in the project repository.

Contributing code and documentation changes

To expand and improve the NEM Developer Center, please find or open an issue about it first. Talk about what you would like to do. It may be that somebody is already working on it, or that there are particular issues that you should know about before implementing the change.

We enjoy working with contributors to get their pull-requests accepted.

In the pull request, choose a title which sums up the changes that you have made, and in the body provide more details about what your changes do. Also mention the number of the issue where discussion has taken place, eg “Closes #123”.
