 Build & Release process
 -----------------------
 
-This is work in progress. Please refer to [#268](https://github.com/picocms/Pico/issues/268) for details.
-
-<!--
-
-Defined below is a specification to which the Build and Release process of Pico should follow. We use `travis-ci` to automate the process, and each commit to `master` should be releasable.
-
-#### Commit phase
-- Commit changes
-- Create & Push Git tag
-- Trigger automatic build process...
-
-Example commit message:
-
-    Pico 1.0.1
-    * [New] ...
-    * [Changed] ...
-
-*Please submit pull-requests with a properly
-formatted commit message/SemVer increase to avoid the need for manual amendments.*
-
-#### Analysis phase
-- Run through `scrutinizer-ci`?
+We're using [Travis CI](https://travis-ci.com) to automate the build & release process of Pico. It generates and deploys [phpDoc](http://phpdoc.org) class docs for new releases and on every commit to the `master` branch. Travis also prepares new releases by generating Pico's pre-built packages and uploading them to GitHub. Please refer to [our `.travis.yml`](https://github.com/picocms/Pico/blob/master/.travis.yml) for details.
 
-#### Packaging phase
-- Run composer locally
-- Create a ZIP archive (so vendor/ is included)
-- Build documentation, output goes to a new folder in the `gh-pages` branch
+As insinuated above, it is important that each commit to `master` is deployable. Once development of a new Pico release is finished, trigger Pico's build & release process by pushing a new Git tag. This tag should reference a (usually empty) commit on `master`, which message should adhere to the following template:
 
-#### Release phase
-- Create new Git release at tag
-- Upload ZIP archive
-- Upload documentation to the `gh-pages` branch
-- Set Symlink for latest documentation (http://picocms.org/docs/latest)
-- Update release information on GitHub with:
-    - Release title (taken from changelog)
-    - Changelog
+```
+Version 1.0.0
 
-#### Announcements
-- Where to announce new Pico release?
+* [Security] ...
+* [New] ...
+* [Changed] ...
+* [Fixed] ...
+* [Removed] ...
+```
 
--->
+Travis CI will draft the new [release on GitHub](https://github.com/picocms/Pico/releases) automatically, but will require you to manually amend the descriptions formatting. The latest Pico version is always available at https://github.com/picocms/Pico/releases/latest, so please make sure to publish this URL rather than version-specific URLs. [Packagist](http://packagist.org/packages/picocms/pico) will be updated automatically.

+- the `PATCH` version (e.g. `1.0.0` to `1.0.1`), we made backwards-compatible bug fixes. It's then sufficient to extract [Pico's latest release][LatestRelease] to your existing installation directory and overwriting all files. Alternatively you can either use the [*source code* of Pico's latest release][LatestRelease] or pull from Pico's Git repository, but are then required to update Pico's [composer][] dependencies manually by running `php composer.phar update`.
 
 - the `MINOR` version (e.g. `1.0` to `1.1`), we added functionality in a backwards-compatible manner, but anyway recommend you to "install" Pico newly. Backup all of your files, empty your installation directory and install Pico as elucidated above. You can then copy your `config/config.php` and `content` directory without any change. If applicable, you can also copy the folder of your custom theme within the `themes` directory. Provided that you're using plugins, also copy all of your plugins from the `plugins` directory.
 
-- the `MAJOR` version (e.g. `1.0` to `2.0`), a appropriate upgrade tutorial will be provided.
+- the `MAJOR` version (e.g. `1.0` to `2.0`), we made incompatible API changes. We will then provide a appropriate upgrade tutorial.
 
 Upgrading Pico 0.8 or 0.9 to Pico 1.0 is a special case. The new `PicoDeprecated` plugin ensures backwards compatibility, so you basically can follow the above upgrade instructions as if we updated the `MINOR` version. However, we recommend you to take some further steps to confine the necessity of `PicoDeprecated` as far as possible. For more information about what has changed with Pico 1.0 and a step-by-step upgrade tutorial, please refer to the [upgrade page of our website][HelpUpgrade].
