+## Roadmap
+
+This library should hopefully fulfil a good number of use cases. However, it still is a bit far
+from a complete solution. In particular, future versions should be able to:
+
+- Write NIFTI files;
+- Provide a more elegant volume API;
+- Handle more kinds of volumes;
+- Provide a real spatial-temporal interpretation of the volume (rather than just voxel-indexed);
+- Maybe add support for NIFTI-2?
+
+There are no deadlines for these features, so your help is much appreciated. Consider filing an [issue](issues) in case something is missing for your use case to work. Pull requests are also welcome.
