+# Branches, versions and releases — complete guideline
+
+## Branches
+
+The project has two main branches: `master` and `next`.
+
+Branch `master` contains the latest stable version of the editor.
+The latest version published to NPM available by default or by the tag `latest`.
+
+Branch `next` used for development the next (release candidate) version of the editor.
+It may contain bug fixes, improvements or features. This version is available in NPM by `next` tag.
+
+## Versions
+
+We use [semantic versioning](https://semver.org) as a main guide for naming updates.
+
+`<major>.<minor>.<patch>`
+
+You need to bump the part of version according the changes:
+
+- `patch` — for bug fixes, docs updates, code style fixes and other changes which do not affect the result project bundle
+- `minor` — for new features with no backward compatibility problems.
+- `major` — for breaking changes without backward compatibility with the api of the previous version of the project.
+
+Pre-release versions may contain additional `-rc.*` suffix.
+
+## Release publishing
+
+> 👉 Stable versions are published to releases from `master` branch.
+
+There is an [action](.github/workflows/publish.yml) that fired on a new release publishing on GitHub.
+
+After update merging, when a new package version is ready to be published,
+create a [new release](https://github.com/codex-team/editor.js/releases/new) with the correct version tag.
+
+Use target version changelog as a description.
+

+
+Then you can publish the release and wait for package publishing via action.
+
+This package version will be published to NPM with default `latest` tag.
+
+### Release candidate publishing
+
+> 👉 Release candidate versions are published to releases from default `next` branch.
+
+If you want to publish release candidate version, use suffix `-rc.*` for package version in package.json file and in tag on releases page.
+
+This package version will be published to NPM with `next` tag.
+
+Stable version: `2.19.0`
+Release candidate: `2.19.1-rc.0`, `2.19.1-rc.1`, ...
+Next version: `2.19.1`
+
+Do not forget to mark this release as a pre-release!
+
+![](https://capella.pics/796de9eb-bbe0-485c-bc8f-9a4cb76641b7.jpg)
+
+## Example pipeline
+
+Let's imagine that package version is `2.19.0` and you want to add some bug fixes and publish an update as `2.19.1`.
+
+1. Merge a single update or a few pulls with fixes to the default branch `next`.
+2. Bump the version up to `2.19.1-rc.0` in the package.json. For the rest rc updates you should bump version number in suffix (to `2.19.1-rc.1` etc).
+3. Create a new release on the releases page with tag `v2.19.1-rc.0` and mark "This is pre-release" checkbox.
+[Action](.github/workflows/publish.yml) will automatically push the package to NPM with tag `next`.
+4. When you ready to publish a release, remove suffix from version name in package.json (`2.19.1-rc.0` -> `v2.19.1`) and push changes.
+5. Merge branch `next` to `master` and create a new release with tag `v2.19.1`.
+Same action will publish a new package as `latest` update.
