+CKEditor 4 - Releases
+=====================
+
+## Releases Code
+
+This repository contains the official release versions of [CKEditor 4](https://ckeditor.com/ckeditor-4/).
+
+There are four versions for each release — `standard-all`, `basic`, `standard`, and `full`.
+They differ in the number of plugins that are compiled into the main `ckeditor.js` file as well as the toolbar configuration.
+
+See the [comparison](https://ckeditor.com/cke4/presets) of the `basic`, `standard`, and `full` installation presets for more details.
+
+The `standard-all` build includes all official CKSource plugins with only those from the `standard` installation preset compiled into the `ckeditor.js` file and enabled in the configuration.
+
+All versions available in this repository were built using [CKBuilder](https://ckeditor.com/cke4/builder), so they are optimized and ready to be used in a production environment.
+
+## Documentation
+
+Developer documentation for CKEditor is available online at: <https://ckeditor.com/docs/>.
+
+## Installation
+
+### Git clone
+
+To install one of the available releases, just clone this repository and switch to the respective branch (see next section):
+
+	git clone -b <release branch> git://github.com/ckeditor/ckeditor4-releases.git
+
+### Git submodule
+
+If you are using git for your project and you want to integrate CKEditor, we recommend to add this repository as a
+[submodule](https://git-scm.com/book/en/v2/Git-Tools-Submodules).
+
+	git submodule add -b <release branch> git://github.com/ckeditor/ckeditor-releases.git <clone dir>
+	git commit -m "Added CKEditor submodule in <clone dir> directory."
+
+### Using Package Managers
+
+See the [Installing CKEditor with Package Managers](https://ckeditor.com/docs/ckeditor4/latest/guide/dev_package_managers.html) article for more details about installing CKEditor with [Bower](https://bower.io), [Composer](https://getcomposer.org/) and [npm](https://www.npmjs.com/).
+
+## Repository Structure
+
+### Branches
+
+This repository contains the following branches:
+
+  - `master` and `latest` &ndash; the latest release of the `standard-all` preset (including betas).
+  - `stable` &ndash; the latest stable release of the `standard-all` preset (non-beta).
+  - `A.B.x` (e.g. `4.3.x`) &ndash; the latest release of the `standard-all` preset in the `A.B` branch.
+  - `(basic|standard|full)/stable` &ndash; the latest stable release tag point (non-beta).
+  - `(basic|standard|full)/latest` &ndash; the latest release tag point (including betas).
+  - `(basic|standard|full)/A.B.x` (e.g. `basic/4.0.x`) &ndash; the latest releases in the `A.B` branch.
+
+### Tags
+
+**Since version 4.3.3** this repository uses the following tag naming rules:
+
+  - `x.y.z` &ndash; contains the `standard-all` editor build, e.g. `4.3.3`, `4.4.0` etc.
+  - `(basic|standard|full)/x.y.z` &ndash; contains the editor build with a given preset, e.g. `basic/4.3.3`.
+
+The version numbers follow the [Semantic Versioning 2.0.0](http://semver.org/) scheme.
+
+Up to version **4.3.2** the tags were released in the following form `x.y[.z]/(basic|standard|full)`.
+For example: `4.0/basic`, `4.0.1/standard`. This convention was changed in CKEditor 4.3.3 to conform to the Semantic Versioning scheme.
+
+## Checking Your Installation
+
+The editor comes with a few sample pages that can be used to verify if the installation succeeded. Take a look at the `samples` directory.
+
+To test your installation, just call the following page for your website:
+
