+## Cheatsheet
+
+### Cheatsheet: Content design, formatting, and language
+
+**[Contact information:](#contact-information)**
+- Use official Kubernetes contact information.
+
+**[Dates and times:](#dates-and-times)**
+- Format dates as `month day, year`. (December 13, 2018)
+- When conveying a date in numerical form, use [ISO 8601] Format: `yyyy-mm-dd`.
+- Use the 24 hour clock when referencing time.
+- Times for single events (example: KubeCon) should be expressed in an absolute
+  time zone such as Pacific Standard Time (PST) or Coordinated Universal Time
+  (UTC).
+- Times for reoccurring events should be expressed in a time zone that follows
+  Daylight Savings Time (DST) such as Pacific Time (PT) or Eastern Time (ET).
+- Supply a link to a globally available time zone converter service.
+  - `http://www.thetimezoneconverter.com/?t=<TIME REFERENCE>&tz=<TZ REFERENCE>`
+
+**[Diagrams, images and other assets:](#diagrams-images-and-other-assets)**
+- Images and other assets should be stored in the same directory as the document
+  that is referencing it.
+- Filenames should be lowercase and descriptive of what they are referencing.
+- Avoid excessively large images or include a smaller one while linking to a
+  higher resolution version of the same image.
+- Use the [Kubernetes icon set] for architectural diagrams.
+
+**[Document Layout:](#document-layout)**
+- Documents should follow the general template of:
+  - Document metadata (if appropriate).
+  - Title in `H1` (a single `#`).
+  - A brief description or summary of the document.
+  - A table of contents.
+  - The general body of document.
+- Do not repeat content. Instead link back to the canonical source.
+- Large content or topic shifts should be separated with a horizontal rule.
+
+**[Formatting text:](#formatting-text)**
+- API objects:
+  - Follow the established [API naming convention] when referring to API Objects.
+  - Do not split API object names into their components.
+  - Use `code` style for API objects or object parameters.
+- Use **bold text** for user interface elements.
+- Use _italics_ to emphasize a new topic or subject for the first time.
+- Use angle brackets (`<` and `>`) to enclose a placeholder reference.
+- Apply `code` styling to:
+  - Filenames, directories, and paths.
+  - Command line examples and flags.
+  - Object field names.
+
+**[Language, grammar and tone:](#language)**
+- Documentation should be written in English.
+- Prefer an active voice and present tense when possible.
+- Use simple and direct language.
+- Use gender-neutral language.
+- Avoid personal pronouns ("I," "we," "us," "our," and "ours").
+- Address the reader as "you" instead of "we".
+- Do not use Latin phrases.
+- Avoid jargon and idioms.
+- If using acronyms, ensure they are clearly defined in the same document.
+- If using an abbreviation, spell it out the first time it is used in the
+  document unless it is commonly known. (example: TCP/IP)
+
+**[Moving a document:](#moving-a-document)**
+- Use `[git-mv]` to move documents.
+- Commit moved documents separately from any other changes.
+- When a document has moved, leave a tombstone file with a removal date in its
+  place.
+  
+**[Punctuation:](#punctuation)**
+- Do not use punctuation in headings.
+- End full sentences with a period.
+  - **Exception:** When a sentence ends with a URL or if the text would be
+    unclear if the period is a part of the previous object or word.
+- Add a single space after a period when beginning a new sentence.
+- Avoid usage of exclamation points unless they are a part of a code example.
+- Use an [Oxford comma] when a list contains 3 or more elements.
+
+**[Quotation:](#quotes)**
+- Use double-quotation marks (`" "`) over single-quotation marks (`' '`).
+  - **Exception:** In code snippets where quotation marks have specific meaning.
+  - **Exception:** When nesting quotation marks inside another set of quotation
+    marks.
+- Punctuation should be outside of quotation marks following the international
+  (British) standard.
+
+
+### Cheatsheet: Markdown
+
+**[Code blocks:](#code-blocks)**
+- When possible, reference the language at the beginning of a Code Block.
+- When a code block is used to reference a shell, do not include the command
+  prompt (`$`).
+  - **Exception:** When a code block is used to display raw shell output.
+- Separate commands from output.
+
+**[Emphasis:](#emphasis)**
+- Use two asterisks (`**`) for **Bold** text.
+- Use an underscore (`_`) for _Italics_.
+- Use two tildes (`~~`) for ~~Strikethrough~~.
+ 
+**[Headings:](#headings)**
+- Use a single `H1` (`#`) Heading per document.
+  - **Exception:** `H1` may be used multiple times in the same document when
+    there is a large content shift or "chapter" change.
+- Follow the Header hierarchy of `H2` > `H3` > `H4` > `H5` > `H6`.
+- Use sentence-style capitalization in titles (first word and proper nouns).
+- Avoid using special characters.
+- Leave exactly 1 new line after a heading.
+- Avoid using links in headings.
+
+**[Horizontal rules:](#horizontal-lines)**
+- Use three dashes (`---`) to denote a horizontal rule.
+- Use a horizontal rule (`---`) to logically separate large sections.
+
+**[Line length:](#line-length)**
+- Prefer an 80 character line limit.
+
+**[Links:](#links)**
+- Prefer using reference style links over inline style links.
+- When linking within the same directory, use a relative link.
+- When linking to a document outside of the current directory, use the absolute
+  path from the root of the repository.
+- When linking to a file in another Kubernetes github repository, use the
+  `k8s.io` url shortener.
+  - git.k8s.io -> github.com/kubernetes
+  - sigs.k8s.io -> github.com/kubernetes-sigs
+
+**[Lists:](#lists)**
+- Capitalize the first character of each entry unless the item is explicitly
+  case sensitive.
+- End each entry with a period if it is a sentence or phrase.
+- Use a colon (`:`) to separate a list item name from the explanatory text.
+- Leave a blank line after each list.
+- Use `-` for unordered lists.
+- For ordered lists repeating `1.` may be used.
+- When inserting a code block into an ordered list, indent (space) an additional
+  two times.
+
+**[Metadata:](metadata)**
+- If the document is intended to be surfaced on the Contributor Site; include a
+  yaml metadata header at the beginning of the document.
+- Metadata must include the `title` attribute.
+
+**[Tables:](#tables)**
+- Use tables for structured information.
+- Tables do not need to adhere to the suggested line length.
+- Avoid long inline links.
+- Do not use excessively wide tables.
+
+---
+
+## Content design, formatting, and language
+
+### Contact information
+
+- Use official Kubernetes contact information.
+  - Use official community contact email addresses. There should be no personal
+    or work contact information included in public documentation; instead use
+    addresses like the [SIG Google groups] or managed accounts such as
+    community@kubernetes.io. 
+  - **Good example:** community@kubernetes.io
+  - **Bad example:** bob@example.com
+
+
+### Dates and times
+
+The Kubernetes Contributor Community spans many regions and time zones.
+Following a consistent pattern and avoiding shorthand improves the readability
+for every member.
+
+- Format dates as `month day, year`. (December 13, 2018)
+  - **Good example:** October 24, 2018
+  - **Bad example:** 10/24/18
+- When conveying a date in numerical form, use [ISO 8601] Format: `yyyy-mm-dd`.
+  - **Good example:** 2018-10-24
+  - **Bad example:** 10/24/18
+- Use the 24 hour clock when referencing time.
+  - **Good example:** 15:30
+  - **Bad example:** 3:30pm
+- Times for single events (example: KubeCon) should be expressed in an absolute
+  time zone such as Pacific Standard Time (PST) or Coordinated Universal Time
+  (UTC).
+  - **Good example:** The Seattle Contributor Summit starts at 9:00 PST
+  - **Bad example:** The Seattle Contributor Summit starts at 9:00 PT
+- Times for reoccurring events should be expressed in a time zone that follows
+  Daylight Savings Time (DST) such as Pacific Time (PT) or Eastern Time (ET).
+  - Times that follow DST are used as they adjusts automatically. If UTC or
+    other non-DST compatible time zones were used, content would have to be
+    updated multiple times per year to adjust times.
+  - **Good example:** 13:30 PT
+  - **Bad example:** 16:30 EST
+- Supply a link to a globally available time zone converter service.
+  - `http://www.thetimezoneconverter.com/?t=<TIME REFERENCE>&tz=<TZ REFERENCE>`
+
+  ```
+  The weekly SIG meeting is at [13:30 PT].
+
+  [13:30 PT]: http://www.thetimezoneconverter.com/?t=13:30&tz=PT%20%28Pacific%20Time%29
+  ```
+
+
+### Diagrams, images and other assets
+
+- Images and other assets should be stored in the same directory as the document
+  that is referencing it.
+- Filenames should be lowercase and descriptive of what they are referencing.
+  - **Good example:** `deployment-workflow.jpg`
+  - **Bad example:** `image1.jpg`
+- Avoid excessively large images or include a smaller one while linking to a
+  higher resolution version of the same image.
+- Use the [Kubernetes icon set] for architectural diagrams.
+
+
+### Document Layout
+
+Adhering to a standard document layout ensures that each page can intuitively 
+be navigated once a reader is familiar with the standard layout.
+
+- Documents should follow the general template of:
+  - Document metadata (if appropriate).
+  - Title in `H1` (a single `#`).
+  - A brief description or summary of the document.
+  - A table of contents.
+  - The general body of document.
+- Do not repeat content. Instead link back to the canonical source.
+  - It is easy for content to become out of sync if it is maintained in
+    multiple places. Linking back to the canonical source ensures that the
+    documentation will be accurate and up to date.
+- Large content or topic shifts should be separated with a horizontal rule.
+
+
+### Formatting text
+
+The formatting guidelines have been selected to mirror or augment the
+[Kubernetes documentation style-guide]. Remaining consistent across the
+different content sources improves the overall readability and understanding of
+the documentation being presented in addition to giving the project a unified
+external appearance.
+
+- API objects:
+  - Follow the established [API naming convention] when referring to API Objects.
+  - Do not split API object names into their components.
+    - **Good example:** A `Pod` contains a `PodTemplateSpec`.
+    - **Bad example:** A `Pod` contains a `Pod Template Spec`.
+  - Use `code` style for API objects or object parameters.
+    - **Good example:** A `Deployment` contains a `DeploymentSpec`.
+    - **Bad example:**  A Deployment contains a DeploymentSpec.
+- Use angle brackets (`<` and `>`) to surround a placeholder references.
+  - **Good example:** `kubectl describe pod <pod-name>`
+  - **Bad example:** `kubectl describe pod pod-name`
+- Use **bold text** for user interface elements.
+  - **Good example:** Select **Other**.
+  - **Bad example:** Select "Other".
+- Use _italic text_ to emphasize a new subject for the first time.
+  - **Good example:** A _cluster_ is a set of nodes.
+  - **Bad example:** A "cluster" is a set of nodes.
+- `Code` styling should be applied to:
+  - Filenames, directories, and paths.
+    - **Good example:** The default manifest path is `/etc/kubernetes/manifests`.
+    - **Bad example:** The default manifest path is /etc/kubernetes/manifests.
+  - Command line examples and flags.
+    - **Good example:** The flag `--advertise-address` is used to denote the
+      IP address on which to advertise the apiserver to members of the cluster.
+    - **Bad example:** The flag --advertise-address is used to denote the IP
+      address on which to advertise the apiserver to members of the cluster.
+  - Object field names.
+    - **Good example:** Set the `externalTrafficPolicy` to Local.
+    - **Bad example:** Set the externalTrafficPolicy to Local.
+
+
+### Language, grammar and tone
+
+- Documentation should be written in English.
+- Prefer an active voice and present tense when possible.
+  - Active voice is when the subject of the sentence performs the action.
+    Whereas with passive voice the subject receives the action. Writing with an
+    active voice in mind easily conveys to the reader who or what is performing
+    the action.
+  - **Good example:** Updating the Deployment triggers a new ReplicaSet to be
+    created.
+  - **Bad example:** A ReplicaSet is created by updating the Deployment.
+- Use simple and direct language.
+  - Avoid using unnecessary or extra language. Be straightforward and direct.
+  - **Good example:** Wait for the Pod to start.
+  - **Bad example:** Please be patient and wait for the Pod to start.
+- Use gender-neutral language.
+  - Avoid gendered pronouns preferring the [singular "they"][singular-they]
+    unless referring to the person's by their preferred gender. For further
+    information on the subject, see [Microsoft's guide to bias-free communication]
+    and [Wikipedia's entry for the Singular they].
+  - **Good example:** chair or moderator
+  - **Bad example:** chairman
+- Avoid personal pronouns ("I," "we," "us," "our," and "ours").
+  - In most cases personal pronouns should be avoided as they can lead to
+    confusion regarding who they are referring to. 
+  - **Good example:** The release-team shepherded the successful release of 1.13.
+  - **Bad example:** We shepherded the successful release of 1.13.
+- Address the reader as "you" instead of "we".
+  - Addressing the reader directly using "you" clearly denotes the target.
+    There is no confusion as there would be with "we" or "us".
+  - **Good example:** You will create a new cluster with kubeadm.
+  - **Bad example:** We will create a new cluster with kubeadm.
+- Do not use Latin phrases.
+  - [Latin phrases] can make it difficult for readers not familiar with them to
+    grasp their meaning. 
+  - Some useful alternatives include:
+
+    | Latin Phrase | Alternative |
+    |:------------:|:-----------:|
+    |     e.g.     | for example |
+    |    et al.    |  and others |
+    |     i.e.     |   that is   |
+    |     via      |    using    |
+
+  - **Good example:** For example Deployments, ReplicaSets...
+  - **Bad example:** e.g. Deployments, ReplicaSets...
+- Avoid jargons and idioms.
+  - Jargon and idioms tend to rely on regional or tribal knowledge. They make
+    it difficult to understand for both newcomers and those whose native
+    language is something other than English. They should be avoided when
+    possible.
+  - **Good example:** Internally, the kube-apiserver...
+  - **Bad example:** Under the hood the kube-apiserver...
+  - **Good example:** We will start the project in early 2019.
+  - **Bad example:** We will kick off the initiative in 2019.
+- If using an abbreviation, spell it out the first time it is used in the
+  document unless it is commonly known. (example: TCP/IP)
+  - Abbreviations in this context applies to abbreviations, acronyms and
+    initialisms.
+  - **Good example:** A _CustomResourceDefinition_ (CRD) extends the Kubernetes
+    API.
+  - **Bad example:** A CRD extends the Kubernetes API.
+
+
+### Moving a Document
+
+- Use `[git-mv]` to move documents.
+  - `git-mv` will safely move/rename a file, directory, or symlink and
+    automatically update the git index.
+  - **Good example:** `git mv /old/mydoc.md /new/mydoc.md`
+  - **Bad example:** `mv /old/mydoc.md /new/mydoc.md`
+- Commit moved documents separately from any other changes.
+  - A separate commit clearly preserves the history of the relocated documents
+    and makes it easier to review.
+- When a document has moved, leave a tombstone file with a removal date in its
+  place.
+  - Tombstones function as a pointer and give users a time to update their own
+    documentation and bookmarks. Their usefulness is time-bounded and should be
+    removed when they would logically no longer serve their purpose.
+    ```markdown
+    This file has moved to https://git.k8s.io/community/contributors/guide/README.md.
+
+    This file is a placeholder to preserve links.  Please remove after 2019-03-10 or the release of kubernetes 1.10, whichever comes first.
+    ```
+
+
+### Punctuation
+
+- Do not use punctuation in headings.
+- End full sentences with a period.
+  - **Exception:** When a sentence ends with a URL or if the text would be
+    unclear if the period is a part of the previous object or word.
+- Add a single space after a period when beginning a new sentence.
+- Avoid usage of exclamation points unless they are a part of a code example.
+- Use an [Oxford comma] when a list contains 3 or more elements.
+  - **Good example:** Deployments, ReplicaSets, and DaemonSets.
+  - **Bad example:** Deployments, ReplicaSets and DaemonSets.
+
+
+### Quotation
+
+- Use double-quotation marks (`" "`) over single-quotation marks (`' '`).
+  - **Exception:** In code snippets where quotation marks have specific meaning.
+  - **Exception:** When nesting quotation marks inside another set of quotation
+    marks.
+- Punctuation should be outside of quotation marks following the international
+  (British) standard.
+
+
+---
+
+
+## Markdown formatting
+
+### Code blocks
+
+- When possible, reference the language at the beginning of a Code Block.
+  - The two markdown renderers used by the Kubernetes community
+    ([GitHub][gh-code-hl-list] and [Hugo][hugo-code-hl-list]) support code
+    highlighting. This can be enabled by supplying the name of the language
+    after the three back-ticks (`` ``` ``) at the start of a code block.
+  - **Good example:**
+    `````
+    ```go
+    import (
+      "fmt"
+      ...
+    )
+    ```
+    `````
+  - **Bad example:**
+    `````
+    ```
+    import (
+      "fmt"
+      ...
+    )
+    ```
+    `````
+- When a code block is used to reference a shell, do not include the command
+  prompt (`$`)
+  - When a code block is referencing a shell, it is implied that it is a
+    command prompt. The exception to this is when a code block is being used
+    for raw shell output such as debug logs. 
+  - **Good example:**
+    ```
+    kubectl get pods -o wide
+    ```
+  - **Bad example:**
+    ```
+    $ kubectl get pods -o wide
+    ```
+- Separate commands from output.
+  - Separating the command from the output makes both the command and output
+    more generally readable.
+  - **Good example:**
+    ```
+    kubectl get pods
+    ```
+    ```
+    NAME     READY     STATUS    RESTARTS   AGE    IP           NODE
+    nginx    1/1       Running   0          13s    10.200.0.4   worker0
+    ```
+  - **Bad example:**
+    ```
+    kubectl get pods
+    NAME     READY     STATUS    RESTARTS   AGE    IP           NODE
+    nginx    1/1       Running   0          13s    10.200.0.4   worker0
+    ```
+
+
+### Emphasis
+
+Markdown has multiple ways of indicating each type of emphasis. Adhering to a
+standard across documentation improves supportability.
+
+- Use two asterisks (`**`) for **Bold** text.
+  - **Good example:** `This is **bold** text.`
+  - **Bad example:** `This should not be used for __bold__.`
+- Use an underscore (`_`) for _Italics_.
+  - **Good example:** This is _italics_.`
+  - **Bad example:**  This should not be used for *italics*.`
+- Use two tildes (`~~`) for ~~Strikethrough~~.
+  - **Good example:** `This is ~~strikethrough~~`
+  - **Bad example:** `This should not be used for ~strikethrough~.`
+
+
+### Headings
+
+ Adhering to a standard across documentation improves both readability and
+ overall supportability across multiple documents.
+
+- Use a single `H1` (`#`) Heading per document.
+  - **Exception:** `H1` may be used multiple times in the same document when
+    there is a large content shift or "chapter" change.
+- Follow the Header hierarchy of `H2` > `H3` > `H4` > `H5` > `H6`.
+- Use sentence-style capitalization in titles (first word and proper nouns).
+- Avoid using special characters.
+- Leave exactly 1 new line after a heading.
+- Avoid using links in headings.
+
+
+### Horizontal rules
+
+Markdown has multiple ways of indicating a horizontal rule. Adhering to a
+standard across documentation improves supportability.
+
+- Use three dashes (`---`) to denote a horizontal rule.
+  - **Good example:** `---`
+  - **Bad example:** `===`
+- Use a horizontal rule (`---`) to logically separate large sections.
+
+
+### Line length
+
+- Prefer an 80 character line limit.
+  - There is no specific general best practice for Markdown line length. The
+    commonly used 80 character guideline is preferable for general text review
+    and editing.
+
+
+### Links
+
+Markdown provides two primary methods to link to content: inline links and
+relative links. However, how and what they're being linked to can vary widely. 
+
+- Prefer using reference style links over inline style links.
+  - Reference links are shorter and easier to read. They have the added benefit
+    of being reusable throughout the entire document. 
+  - The link itself should be at the bottom of the document. If the document is
+    large or covers many topics, place the link at the end of the logical
+    chapter or section.
+  - **Example:**
+    ```
+    See the [Code of Conduct] for more information.
+
+    [code of conduct]: https://git.k8s.io/community/code-of-conduct.md
+    ```
+  - **Example:**
+    ```
+    See the [Code of Conduct][coc] for more information.
+
+    [coc]: https://git.k8s.io/community/code-of-conduct.md
+    ```
+- When linking within the same directory, use a relative link.
+  - Links to files within the same directory are short and readable already.
+    They do not warrant expanding the full path.
+  - When the file is referenced multiple times within the same document,
+    consider using a reference link for a quicker shorthand reference.
+  - **Example:**
+    ```
+    See the [Code of Conduct](code-of-conduct.md) for more information
+    ```
+  - **Example:**
+    ```
+    See the [Code of Conduct][coc] for more information
+
+    [coc]: code-of-conduct.md
+    ```
+- When linking to a document outside of the current directory, use the absolute
+  path from the root of the repository.
+  - Using the absolute path ensures that if the source document is relocated,
+    the link to the target or destination document will remain intact and not
+    have to be updated.
+  - **Example:**
+    ```
+    See the [Coding Convention] doc for more information.
+
+    [Coding Convention]: /contributors/guide/coding-conventions.md
+    ```
+- When linking to a file in another Kubernetes github repository, use the
+  `k8s.io` url shortener.
+  - The shorthand version will auto-expand linking to documents within the
+    master branch and can be used for multiple purposes. 
+
+    |      Short URL      |            Expanded URL            |
+    |:-------------------:|:----------------------------------:|
+    |  https://git.k8s.io |    https://github.com/kubernetes   |
+    | https://sigs.k8s.io | https://github.com/kubernetes-sigs |
+
+  - **Example:**
+    ```
+    The super cool [prow tool] resides in the test-infra repo under the kubernetes organization
+
+    [prow tool]: https://git.k8s.io/test-infra/prow/README.md
+    ```
+
+
+### Lists
+
+ Adhering to a standard across documentation improves both readability and
+ overall supportability across multiple documents.
+
+- Capitalize the first character of each entry unless the item is explicitly
+  case sensitive.
+- End each entry with a period if it is a sentence or phrase.
+- Use a colon (`:`) to separate a list item name from the explanatory text.
+- Leave a blank line after each list.
+- Use `-` for unordered lists.
+- For ordered lists a repeating `1.` may be used.
+- When inserting a code block into an ordered list, indent (space) an additional
+  two times.
+
+
+### Metadata
+
+- If the document is intended to be surfaced on the Contributor Site; include a
+  yaml metadata header at the beginning of the document.
+  - If the document is to be added to the Contributor Site, adding metadata
+    at the beginning of the document will improve the overall presentation of
+    the information. This metadata is similar to the metadata used in the
+    KEP process and is often referred to as _Frontmatter_ in common static
+    site generators such as [Jekyll] and [Hugo].
+  - The metadata header is a yaml block between two sets of `---`.
+  - **Example:**
+    ```
+    ---
+    title: Super Awesome Doc
+    ---
+    ```
+- Metadata must include the `title` attribute.
+  - `title` will be used as the title of the document when rendered with
+    [Hugo].
+
+
+### Tables
+
+- Use tables for structured information.
+  - **Example:**
+    ```
+    |    Column 1    |    Column 2    |    Column 3    |
+    |:--------------:|:--------------:|:--------------:|
+    |     test 1     |     test 2     |     test 3     |
+    | another test 1 | another test 2 | another test 3 |
+    ```
+- Tables do not need to adhere to the suggested line length.
+  - Markdown tables have an inherently longer line length, and cannot be
+    line wrapped. 
+- Avoid long inline links.
+  - Long inline links can make it difficult to work with markdown tables.
+    Prefer to use reference style links instead.
+- Do not use excessively wide tables.
+  - Large wide tables do not render well. Try to break the information down
+    into something more easily presentable.
