+
+---
+
+**Example configurations**
+
+To create an archive with a name of the current build:
+
+```yaml
+job:
+  artifacts:
+    name: "$CI_BUILD_NAME"
+```
+
+To create an archive with a name of the current branch or tag including only

+
+```yaml
+job:
+   artifacts:
+     name: "$CI_BUILD_REF_NAME"
+     untracked: true
+```
+
+To create an archive with a name of the current build and the current branch or

+
+```yaml
+job:
+  artifacts:
+    name: "${CI_BUILD_NAME}_${CI_BUILD_REF_NAME}"

+    name: "${CI_BUILD_STAGE}_${CI_BUILD_REF_NAME}"
+    untracked: true
+```
+
+---
+
+If you use **Windows Batch** to run your shell scripts you need to replace
+`$` with `%`:

+### dependencies

+>**Note:**
+Introduced in GitLab 8.6 and GitLab Runner v1.1.1.
+
+This feature should be used in conjunction with [`artifacts`](#artifacts) and
+allows you to define the artifacts to pass between different builds.
+
+Note that `artifacts` from previous [stages](#stages) are passed by default.
+
+To use this feature, define `dependencies` in context of the job and pass
+a list of all previous builds from which the artifacts should be downloaded.
+You can only define builds from stages that are executed before the current one.
+An error will be shown if you define builds from the current stage or next ones.
+
+---
+
+In the following example, we define two jobs with artifacts, `build:osx` and
+`build:linux`. When the `test:osx` is executed, the artifacts from `build:osx`
+will be downloaded and extracted in the context of the build. The same happens
+for `test:linux` and artifacts from `build:linux`.
+
+The job `deploy` will download artifacts from all previous builds because of
+the [stage](#stages) precedence:
+
+```yaml
+build:osx:
+  stage: build
+  script: make build:osx
+  artifacts:
+    paths:

+## Hidden jobs
+
+>**Note:**
+Introduced in GitLab 8.6 and GitLab Runner v1.1.1.
+
+Jobs that start with a dot (`.`) will be not processed by GitLab CI. You can
+use this feature to ignore jobs, or use the
+[special YAML features](#special-yaml-features) and transform the hidden jobs
+into templates.
+
+In the following example, `.job_name` will be ignored:
+
+```yaml
+.job_name:
+  script:
+    - rake spec
+```
+
+## Special YAML features
+
+It's possible to use special YAML features like anchors (`&`), aliases (`*`)
+and map merging (`<<`), which will allow you to greatly reduce the complexity
+of `.gitlab-ci.yml`.
+
+Read more about the various [YAML features](https://learnxinyminutes.com/docs/yaml/).
+
+### Anchors
+
+>**Note:**
+Introduced in GitLab 8.6 and GitLab Runner v1.1.1.
+
+YAML also has a handy feature called 'anchors', which let you easily duplicate
+content across your document. Anchors can be used to duplicate/inherit
+properties, and is a perfect example to be used with [hidden jobs](#hidden-jobs)
+to provide templates for your jobs.
+
+The following example uses anchors and map merging. It will create two jobs,
+`test1` and `test2`, that will inherit the parameters of `.job_template`, each
+having their own custom `script` defined:
+
+```yaml
+.job_template: &job_definition  # Hidden job that defines an anchor named 'job_definition'
+  image: ruby:2.1
+  services:
+    - postgres
+    - redis
+
+test1:
+  <<: *job_definition           # Merge the contents of the 'job_definition' alias
+  script:
+    - test1 project
+
+test2:
+  <<: *job_definition           # Merge the contents of the 'job_definition' alias
+  script:
+    - test2 project
+```
+
+`&` sets up the name of the anchor (`job_definition`), `<<` means "merge the
+given hash into the current one", and `*` includes the named anchor
+(`job_definition` again). The expanded version looks like this:
+
+```yaml
+.job_template:
+  image: ruby:2.1
+  services:
+    - postgres
+    - redis
+
+test1:
+  image: ruby:2.1
+  services:
+    - postgres
+    - redis
+  script:
+    - test1 project
+
+test2:
+  image: ruby:2.1
+  services:
+    - postgres
+    - redis
+  script:
+    - test2 project
+```
+
+Let's see another one example. This time we will use anchors to define two sets
+of services. This will create two jobs, `test:postgres` and `test:mysql`, that
+will share the `script` directive defined in `.job_template`, and the `services`
+directive defined in `.postgres_services` and `.mysql_services` respectively:
+
+```yaml
+.job_template: &job_definition
+  script:
+    - test project
+
+.postgres_services:
+  services: &postgres_definition
+    - postgres
+    - ruby
+
+.mysql_services:
+  services: &mysql_definition
+    - mysql
+    - ruby
+
+test:postgres:
+  << *job_definition
+  services: *postgres_definition
+
+test:mysql:
+  << *job_definition
+  services: *mysql_definition
+```
+
+The expanded version looks like this:
+
+```yaml
+.job_template:
+  script:
+    - test project
+
+.postgres_services:
+  services:
+    - postgres
+    - ruby
+
+.mysql_services:
+  services:
+    - mysql
+    - ruby
+
+test:postgres:
+  script:
+    - test project
+  services:
+    - postgres
+    - ruby
+
+test:mysql:
+  script:
+    - test project
+  services:
+    - mysql
+    - ruby
+```
+
+You can see that the hidden jobs are conveniently used as templates.

doc/development/scss_styleguide.md

+# SCSS styleguide
+
+This style guide recommends best practices for SCSS to make styles easy to read,
+easy to maintain, and performant for the end-user.
+
+## Rules
+
+### Naming
+
+CSS classes should use the `lowercase-hyphenated` format rather than
+`snake_case` or `camelCase`.
+
+```scss
+// Bad
+.class_name {
+  color: #fff;
+}
+
+// Bad
+.className {
+  color: #fff;
+}
+
+// Good
+.class-name {
+  color: #fff;
+}
+```
+
+### Formatting
+
+You should always use a space before a brace, braces should be on the same
+line, each property should each get its own line, and there should be a space
+between the property and its value.
+
+```scss
+// Bad
+.container-item { 
+  width: 100px; height: 100px;
+  margin-top: 0;
+}
+
+// Bad
+.container-item
+{
+  width: 100px;
+  height: 100px;
+  margin-top: 0;
+}
+
+// Bad
+.container-item{
+  width:100px;
+  height:100px;
+  margin-top:0;
+}
+
+// Good
+.container-item {
+  width: 100px;
+  height: 100px;
+  margin-top: 0;
+}
+```
+
+Note that there is an exception for single-line rulesets, although these are 
+not typically recommended.
+
+```scss
+p { margin: 0; padding: 0; }
+```
+
+### Colors
+
+HEX (hexadecimal) colors short-form should use shortform where possible, and 
+should use lower case letters to differenciate between letters and numbers, e.
+g. `#E3E3E3` vs. `#e3e3e3`.
+
+```scss
+// Bad
+p {
+  color: #ffffff;
+}
+
+// Bad
+p {
+  color: #FFFFFF;
+}
+
+// Good
+p {
+  color: #fff;
+}
+```
+
+### Indentation
+
+Indentation should always use two spaces for each indentation level.
+
+```scss
+// Bad, four spaces
+p {
+    color: #f00;
+}
+
+// Good
+p {
+  color: #f00;
+}
+```
+
+### Semicolons
+
+Always include semicolons after every property. When the stylesheets are 
+minified, the semicolons will be removed automatically.
+
+```scss
+// Bad
+.container-item {
+  width: 100px;
+  height: 100px
+}
+
+// Good
+.container-item {
+  width: 100px;
+  height: 100px;
+}
+```
+
+### Shorthand
+
+The shorthand form should be used for properties that support it.
+
+```scss
+// Bad
+margin: 10px 15px 10px 15px;
+padding: 10px 10px 10px 10px;
+
+// Good
+margin: 10px 15px;
+padding: 10px;
+```
+
+### Zero Units
+
+Omit length units on zero values, they're unnecessary and not including them 
+is slightly more performant.
+
+```scss
+// Bad
+.item-with-padding {
+  padding: 0px;
+}
+
+// Good
+.item-with-padding {
+  padding: 0;
+}
+```
+
+### Selectors with a `js-` Prefix
+Do not use any selector prefixed with `js-` for styling purposes. These 
+selectors are intended for use only with JavaScript to allow for removal or 
+renaming without breaking styling.
+
+## Linting
+
+We use [SCSS Lint][scss-lint] to check for style guide conformity. It uses the 
+ruleset in `.scss-lint.yml`, which is located in the home directory of the 
+project.
+
+To check if any warnings will be produced by your changes, you can run `rake 
+scss_lint` in the GitLab directory. SCSS Lint will also run in GitLab CI to 
+catch any warnings.
+
+If the Rake task is throwing warnings you don't understand, SCSS Lint's 
+documentation includes [a full list of their linters][scss-lint-documentation].
+
+### Fixing issues
+
+If you want to automate changing a large portion of the codebase to conform to 
+the SCSS style guide, you can use [CSSComb][csscomb]. First install
+[Node][node] and [NPM][npm], then run `npm install csscomb -g` to install 
+CSSComb globally (system-wide). Run it in the GitLab directory with 
+`csscomb app/assets/stylesheets` to automatically fix issues with CSS/SCSS.
+
+Note that this won't fix every problem, but it should fix a majority.
