-## Open-source, not open-contribution
+## Contribution Policy
 
-[Similar to SQLite](https://www.sqlite.org/copyright.html), Litestream is open
-source but closed to contributions. This keeps the code base free of proprietary
-or licensed code but it also helps me continue to maintain and build Litestream.
+Initially, Litestream was closed to outside contributions. The goal was to
+reduce burnout by limiting the maintenance overhead of reviewing and validating
+third-party code. However, this policy is overly broad and has prevented small,
+easily testable patches from being contributed.
 
-As the author of [BoltDB](https://github.com/boltdb/bolt), I found that
-accepting and maintaining third party patches contributed to my burn out and
-I eventually archived the project. Writing databases & low-level replication
-tools involves nuance and simple one line changes can have profound and
-unexpected changes in correctness and performance. Small contributions
-typically required hours of my time to properly test and validate them.
+Litestream is now open to code contributions for bug fixes only. Features carry
+a long-term maintenance burden so they will not be accepted at this time.
+Please [submit an issue][new-issue] if you have a feature you'd like to
+request.
+
+If you find mistakes in the documentation, please submit a fix to the
+[documentation repository][docs].

-I am grateful for community involvement, bug reports, & feature requests. I do
-not wish to come off as anything but welcoming, however, I've
-made the decision to keep this project closed to contributions for my own
-mental health and long term viability of the project.
