 Commit structure
 ----------------
 
-Each commit message consists of a header, a body and a footer. The header has a
-special format that includes a type, a scope and a subject.
+Each commit message needs to specify the semver-type. Which can be `patch|minor|major`.
+See the [Semantic Versioning][semver] specification for a more detailed explanation of the meaning of these types.

 scope, and the body should be wrapped at 72 characters.
 
-Type
-----
-
-Must be one of the following:
-
-- `feat`: A new feature.
-- `fix`: A bug fix.
-- `minifix`: A minimal fix that doesn't warrant an entry in the CHANGELOG.
-- `docs`: Documentation only changes.
-- `style`: Changes that do not affect the meaning of the code (white-space,
-formatting, missing semi-colons, JSDoc annotations, comments, etc).
-- `refactor`: A code change that neither fixes a bug nor adds a feature.
-- `perf`: A code change that improves performance.
-- `test`: Adding missing tests.
-- `chore`: Changes to the build process or auxiliary tools and libraries.
-- `upgrade`: A version upgrade of a project dependency.
-
-Scope
------
-
-The scope is required for types that make sense, such as `feat`, `fix`,
-`test`, etc. Certain commit types, such as `chore` might not have a clearly
-defined scope, in which case its better to omit it.
-
-Subject
--------
-
-The subject should contain a short description of the change:
-
-- Use the imperative, present tense.
-- Don't capitalize the first letter.
-- No dot (.) at the end.
-
-Footer
-------
-
-The footer contains extra information about the commit, such as tags.

-### `Change-Type: <type>`
-
-This tag is used to determine the change type that a commit introduces. The
-following types are supported:
-
-- `major`
-- `minor`
-- `patch`
-
-This tag can be omitted for commits that don't change the application from the
-user's point of view, such as for refactoring commits.
-
-Examples:
-
-```
-Change-Type: major
-Change-Type: minor
-Change-Type: patch
-```
-
-See the [Semantic Versioning][semver] specification for a more detailed
-explanation of the meaning of these types.
-
-### `Changelog-Entry: <message>`
-
-This tag is used to describe the changes introduced by the commit in a more
-human style that would fit the `CHANGELOG.md` better.
-
-If the commit type is either `fix` or `feat`, the commit will take part in the
-CHANGELOG. If this tag is not defined, then the commit subject will be used
-instead.
-
-You explicitly can use this tag to make a commit whose type is not `fix` nor
-`feat` appear in the `CHANGELOG.md`.
-
-Since whatever your write here will be shown *as it is* in the `CHANGELOG.md`,
-take some time to write a decent entry. Consider the following guidelines:
-
-- Use the imperative, present tense.
-- Capitalize the first letter.
-
-There is no fixed length limit for the contents of this tag, but always strive
-to make as short as possible without compromising its quality.
-
-Examples:
-
-```
-Changelog-Entry: Fix EPERM errors when flashing to a GPT drive.
-```
-
-Complete examples
------------------

-```
-fix(GUI): ignore extensions before the first non-compressed extension
-
-Currently, we extract all the extensions from an image path and report back
-that the image is invalid if *any* of the extensions is not valid , however
-this can cause trouble with images including information between dots that are
-not strictly extensions, for example:
-
-    elementaryos-0.3.2-stable-i386.20151209.iso
-
-Etcher will consider `20151209` to be an invalid extension and therefore
-will prevent such image from being selected at all.
-
-As a way to allow these corner cases but still make use of our enforced check
-controls, the validation routine now only consider extensions starting from the
-first non compressed extension.
-
-Change-Type: patch
-Changelog-Entry: Don't interpret image file name information between dots as image extensions.
-Fixes: https://github.com/balena-io/etcher/issues/492

-```
-upgrade: etcher-image-write to v5.0.2
-
-This version contains a fix to an `EPERM` issue happening to some Windows user,
-triggered by the `write` system call during the first ~5% of a flash given that
-the operating system still thinks the drive has a file system.
-
-Change-Type: patch
-Changelog-Entry: Upgrade `etcher-image-write` to v5.0.2.
-Link: https://github.com/balena-io-modules/etcher-image-write/blob/master/CHANGELOG.md#502---2016-06-27
-Fixes: https://github.com/balena-io/etcher/issues/531
-```
-
-***
-
-```
-feat(GUI): implement update notifier functionality
-
-Auto-update functionality is not ready for usage. As a workaround to
-prevent users staying with older versions, we now check for updates at
-startup, and if the user is not running the latest version, we present a
-modal informing the user of the availiblity of a new version, and
-provide a call to action to open the Etcher website in his web browser.
-
-Extra features:
-
-- The user can skip the update, and tell the program to delay the
-notification for 7 days.
-
-Misc changes:
-
-- Center modal with flexbox, to allow more flexibility on the modal height.
-interacting with the S3 server.
-- Implement `ManifestBindService`, which now serves as a backend for the
-`manifest-bind` directive to allow the directive's functionality to be
-re-used by other services.
-- Namespace checkbox styles that are specific to the settings page.
-
-Change-Type: minor
-Changelog-Entry: Check for updates and show a modal prompting the user to download the latest version.

 Updating a dependency
 ---------------------
 
-Given we use [npm shrinkwrap][shrinkwrap], we have to take extra steps to make

-dependency.
-
-Use the following steps to ensure everything goes flawlessly:
-
-- Run `make electron-develop` to ensure you don't have extraneous dependencies
-  you might have brought during development, or you are running older
-  dependencies because you come from another branch or reference.
-
-- Install the new version of the dependency. For example: `npm install --save
-  <package>@<version>`. This will update the `npm-shrinkwrap.json` file.

+- Install new version of dependency using npm
 - Commit *both* `package.json` and `npm-shrinkwrap.json`.

 Release Types
 -------------
 
-Etcher supports **production** and **snapshot** release types. Each is
-published to a different S3 bucket, and production release types are code
-signed, while snapshot release types aren't and include a short git commit-hash
-as a build number. For example, `1.0.0-beta.19` is a production release type,
-while `1.0.0-beta.19+531ab82` is a snapshot release type.
-
-In terms of comparison: `1.0.0-beta.19` (production) < `1.0.0-beta.19+531ab82`
-(snapshot) < `1.0.0-rc.1` (production) < `1.0.0-rc.1+7fde24a` (snapshot) <
-`1.0.0` (production) < `1.0.0+2201e5f` (snapshot). Keep in mind that if you're
-running a production release type, you'll only be prompted to update to
-production release types, and if you're running a snapshot release type, you'll
-only be prompted to update to other snapshot release types.
-
-The build system creates (and publishes) snapshot release types by default, but
-you can build a specific release type by setting the `RELEASE_TYPE` make
-variable.  For example:
-
-```sh
-make <target> RELEASE_TYPE=snapshot
-make <target> RELEASE_TYPE=production
-```
-
-We can control the version range a specific Etcher version will consider when
-showing the update notification dialog by tweaking the `updates.semverRange`
-property of `package.json`.
-
-Update Channels
----------------
-
-Etcher has a setting to include the unstable update channel. If this option is
-set, Etcher will consider both stable and unstable versions when showing the
-update notifier dialog. Unstable versions are the ones that contain a `beta`
-pre-release tag. For example:
-
-- Production unstable version: `1.4.0-beta.1`
-- Snapshot unstable version: `1.4.0-beta.1+7fde24a`
-- Production stable version: `1.4.0`
-- Snapshot stable version: `1.4.0+7fde24a`
+Etcher supports **pre-release** and **final** release types as does Github. Each is
+published to Github releases.
+The release version is generated automatically from the commit messasges.
