+## Releases
+
+We release packages and upload them to PyPI (wheels and source tarballs).
+
+- https://pypi.python.org/pypi/acme
+- https://pypi.python.org/pypi/letsencrypt
+- https://pypi.python.org/pypi/letsencrypt-apache
+- https://pypi.python.org/pypi/letsencrypt-nginx
+- https://pypi.python.org/pypi/letshelp-letsencrypt
+
+The following scripts are used in the process:
+
+- https://github.com/letsencrypt/letsencrypt/blob/master/tools/release.sh
+- https://gist.github.com/kuba/b9a3a2ca3bd35b8368ef
+
+We currently version as `0.0.0.devYYYYMMDD`, and will change at GA time to the following scheme:
+- `0.1.0`
+- `0.2.0dev` for developement in `master`
+- `0.2.0` (only temporarily in `master`)
+- ...
+
+Tracking issue for non-dev release scripts: https://github.com/letsencrypt/letsencrypt/issues/1185
+
+## Notes for package maintainers
+
+0. Please use our releases, not `master`!
+
+1. Do not package `letsencrypt-compatibility-test` - it's only used internally.
+
+2. `letsencrypt-renewer` should be added to crontab... but it currently doesn't work well
+
+3. `letsencrypt.client` provides developer API so it should be possible to `import letsencrypt.client` when the package is installed (`letsencrypt` vs `python-letsencrypt` debate for Debian).
+
+4. `jws` is an internal script for `acme` module and it doesn't have to be packaged - it's mostly for debugging: you can use it as `echo foo | jws sign | jws verify`.
+
+5. Do get in touch with us. We are happy to make any changes that will make packaging easier. If you need to apply some patches don't do it downstream - make a PR here.
