+## Tag Driven Releasing
+
+### Background Reading
+
+  - http://docs.travis-ci.com/user/environment-variables/
+  - http://docs.travis-ci.com/user/encryption-keys/
+  - http://docs.travis-ci.com/user/encrypting-files/
+
+### Initial setup for the repository
+
+To configure tag driven releases from Travis CI.
+
+  1. Generate a key pair for this repository with `./admin/genKeyPair.sh`.
+     Edit `.travis.yml` and `admin/build.sh` as prompted.
+  1. Publish the public key to https://pgp.mit.edu
+  1. Store other secrets as encrypted environment variables with `admin/encryptEnvVars.sh`.
+     Edit `.travis.yml` as prompted.
+  1. Edit `.travis.yml` to use `./admin/build.sh` as the build script,
+     and edit that script to use the tasks required for this project.
+  1. Edit `build.sbt`'s `scalaVersionsByJvm in ThisBuild` to select Scala and JVM version
+     combinations that will be used for publishing.
+
+It is important to add comments in `.travis.yml` to identify the name
+of each environment variable encoded in a `:secure` section.
+
+After these steps, your `.travis.yml` should contain config of the form:
+
+```
+language: scala
+
+env:
+  global:
+    # PGP_PASSPHRASE
+    - secure: "XXXXXX"
+    # SONA_USER
+    - secure: "XXXXXX"
+    # SONA_PASS
+    - secure: "XXXXXX"
+
+script: admin/build.sh
+
+jdk:
+  - openjdk6
+  - oraclejdk8
+
+notifications:
+  email:
+    - a@b.com
+```
+
+If Sonatype credentials change in the future, step 3 can be repeated
+without generating a new key.
+
+### Testing
+
+  1. Follow the release process below to create a dummy release (e.g., `v0.1.0-TEST1`).
+     Confirm that the release was staged to Sonatype but do not release it to Maven
+     central. Instead, drop the staging repository.
+
+### Performing a release
+
+  1. Create a GitHub "Release" with a corresponding tag (e.g., `v0.1.1`) via the GitHub
+     web interface.
+  1. The release will be published using the Scala and JVM version combinations specified
+     in `scalaVersionsByJvm` in `build.sbt`.
+     - If you need to release against a different Scala version, include the Scala version
+       and the JVM version to use in the tag name, separated by `#`s (e.g., `v0.1.1#2.13.0-M1#8`).
+       Note that the JVM version needs to be listed in `.travis.yml` for the build to run.
+  1. Travis CI will schedule a build for this release. Review the build logs.
+  1. Log into https://oss.sonatype.org/ and identify the staging repository.
+  1. Sanity check its contents.
+  1. Release staging repository to Maven and send out release announcement.
