+Please note that:
+- **Travis.org** is used for publishing
+- Plugin is automatically deployed to Jetbrains Plugin Registry when new tag is pushed (see `deploy` in [.travis.yml](.travis.yml))
+- The next version code will be added to gradle.properties
+  - So you can start working on the next version right away
+- `[skip ci]` git commit message prefix tells Travis not to execute a build (because unnecessary) 
+- JetBrains credentials are [stored in Travis](https://travis-ci.org/neueda/jetbrains-plugin-graph-database-support/settings#ember7449)
+  - Currently, only INTELLIJ_TOKEN environment variable is needed for publishing
