+# Releasing Task
+
+The release process of Task is done is done with the help of
+[GoReleaser][goreleaser]. You can test the release process locally by calling
+the `test-release` task of the Taskfile.
+
+The Travis CI should release automatically when a new
+Git tag is pushed to master, either for the artifact uploading (raw executables
+and DEB and RPM packages) and publishing of a new version in the
+[Homebrew tap][homebrewtap].
+
+# Snapcraft
+
+The exception is the publishing of a new version of the
+[snap package][snappackage]. This current require two steps after publishing
+the binaries:
+
+* Updating the current version on [snapcraft.yaml][snapcraftyaml];
+* Moving either the `i386` and `amd64` new artifacts to the stable channel on
+the [Snapscraft dashboard][snapcraftdashboard]
