+# Roadmap
+
+This document describes the roadmap for coverlet showing priorities.  
+Maintain coverlet means like any other project two things, answer/resolve soon as possible new issues that are blocking our users an second improve product with new features and enhancements in different areas.  
+All coverlet issues are labeled and categorized to better support this activites.
+
+As soon as an issue is open is labeled with `untriaged` if not immediately solvable(we need to do some debugging/PoC to understand where is the issue).  
+After triage a final correct label is applied and will be taken into account depending on priority order.  
+We use `needs more info` if we're waiting for answers.
+
+Default priority order "should" be:
+
+1) Bugs: we should fix bugs as soon as possible and for first bugs related to coverage because this is the goal of coverlet.
+
+Coverage bugs: https://github.com/tonerdo/coverlet/issues?q=is%3Aissue+is%3Aopen+label%3Abug+label%3Atenet-coverage  
+Other bugs: https://github.com/tonerdo/coverlet/issues?q=is%3Aissue+is%3Aopen+label%3Abug
+
+2) New features: analyze and add new features, we have three drivers so features could be related to one of these.
+
+Feature requests: https://github.com/tonerdo/coverlet/issues?q=is%3Aissue+is%3Aopen+label%3Afeature-request
+
+3) Performance: we never worked on performance aspect of coverlet, it makes sense for a "new project with some hope", but today coverlet is the facto the dotnet coverage tool, so we HAVE TO approach this aspect.
+
+Performance issues: https://github.com/tonerdo/coverlet/issues?q=is%3Aissue+is%3Aopen+label%3Atenet-performance
+
+Some new features have got a `Discussion` label if we don't have and agreement yet on semantics.  
+Discussions: https://github.com/tonerdo/coverlet/issues?q=is%3Aissue+is%3Aopen+label%3Adiscussion
+
+## New features roadmap
+
+This is the list of features we should develop soon as possible:
+
+### High priority
+
+- https://github.com/tonerdo/coverlet/issues/328 Option to ignore field/property initializers and auto-implemented properties
+
+- Allow merge reports solution wide on all flavours  https://github.com/tonerdo/coverlet/issues/662 https://github.com/tonerdo/coverlet/issues/357
+
+- https://github.com/tonerdo/coverlet/issues/804#issuecomment-611487750 Some perf improvements
+
+### Low priority
+
+- https://github.com/tonerdo/coverlet/issues/808 Rethink hits reports strategy
+- https://github.com/tonerdo/coverlet/issues/705 Support coverage on netfx for collectors integration
+
+## Maintainers discussion channel
+
+[As maintainers we should try to find a way to keep in synch, we could use a chat where we can "take note" of progress and if possible answer to questions/doubt, I know this is OSS, but it's hard keep project at high level without "more ideas".]
