+# Releasing Terraform
+
+This document contains details about the Terraform release process.
+
+## Schedule
+
+Terraform currently has no fixed release schedule, the HashiCorp maintainers
+can usually give a feel for roughly when the next release is planned.
+
+## Versioning
+
+As a pre-1.0 project, we use the MINOR and PATCH versions as follows:
+
+ * a `MINOR` version increment indicates a release that may contain backwards
+   incompatible changes
+ * a `PATCH` version increment indicates a release that may contain bugfixes as
+   well as additive (backwards compatible) features and enhancements
+
+## Process
+
+For maintainer documentation purposes, here is the current release process:
+
+```sh
+# Verify tests pass
+make test
+
+# Prep release commit
+export VERSION="vX.Y.Z"
+# Edit CHANGELOG, adding current date to unreleased version header
+# Edit version.go, setting VersionPrelease to empty string
+
+# Snapshot dependency information
+godep save
+mv Godeps/Godeps.json deps/$(echo $VERSION | sed 's/\./-/g').json
+rm -rf Godeps
+
+# Make and tag release commit
+git commit -a -m "${VERSION}"
+git tag -m "${VERSION}" "${VERSION}"
+
+# Build release in Vagrant machine
+vagrant destroy -f; vagrant up # Build a fresh VM for a clean build
+vagrant ssh
+cd /opt/gopath/src/github.com/hashicorp/terraform/
+make release
+
+# Zip and push release to bintray
+export BINTRAY_API_KEY="..."
+./scripts/dist "X.Y.Z" # no `v` prefix here
+
+# -- "Point of no return" --
+# -- Process can be aborted safely at any point before this --
+
+# Push the release commit and tag
+git push origin master
+git push origin vX.Y.Z
+
+# Click "publish" on the release from the Bintray Web UI
+
+# -- Release is complete! --
+
+# Make a follow-on commit to master restoring VersionPrerelease to "dev" and
+setting up a new CHANGELOG section.
+```
