+# Documentation 
+
+This style guide is primarily for use with authoring documentation. 
+
+
+## General guidelines
+
+- Use sentence case, even in titles (do not punctuate the title, though)
+- Use the second person
+- Use the active voice
+- Use plural nouns and pronouns (*they*, *their*, or *them*), especially when
+  the specific number is uncertain (i.e., "Set up your environments" even though
+  you don't know if the user will have one or many environments)
+- When writing documentation titles, use the noun form, not the gerund form (e.g., "Environment
+  Management" instead of "Managing Environments")
+- Context matters when you decide whether to capitalize something or not. For
+  example, ["A Job creates one or more
+  Pods..."](https://kubernetes.io/docs/concepts/workloads/controllers/job/) is
+  correct when writing about Kubernetes. However, in other contexts, neither
+  *job* nor *pods* would be capitalized. Please follow the conventions set forth
+  by the relevant companies and open source communities.
+
+## Third-party references

+
+## How to format text
+
+Below summarizes the text-formatting conventions you should follow.
+
+### Bold
+
+Use **bold** formatting when referring to UI elements.
+
+### Italics
+
+Use *italics* for:
+
+- Parameter names
+- Mathematical and version variables
+
+### Code font
+
+Use *code font* for:
+
+- User text input
+- Command-line utility names
+- DNS record types
+- Environment variable names (e.g., `PATH`)
+- Filenames, filename extensions, and paths
+- Folders and directories
+- HTTP verbs, status codes, and content-type values
+- Placeholder variables
+
+Use *code blocks* for code samples and other blocks of code. Be sure to indicate
+the language your using to apply the proper syntax highlighting.
+
+```text
+This is a codeblock.
+```
+
+For code that you want users to enter via a command-line interface, use
+`console`, not `bash`.
+
+### Punctuation
+
+Do not use the ampersand (&) as a shorthand for *and* unless you're referring to a
+UI element or the name of something that uses *&*.
+
+You can use the symbol `~` in place of the word *approximately*.
+
+### UI elements
+
+When referring to UI elements, including the names for buttons, menus, dialogs,
+and anything that has a name visible to the user, use bold font.
+
+**Example:** On the **Environment Overview** page, click **Configure SSH**.
+
+Don't use code font for UI elements unless it is rendered based on previously entered
+text. For example, if you tell the user to provide the environment name as
+`myEnvironment`, then use both bold and cold font when referring to the name.
+
+**Example**: Click **`myEnvironment`**.
+
+When writing out instructions that involve UI elements, both of the following options are acceptable:
+
+- Go to **Manage** > **Users**.
+- In the **Manage** menu, click **Users**.
+
+## Product-specific references
+
+Below summarizes the guidelines regarding how Coder terms should be used.
+
+### Capitalized terms
+
+The only Coder-specific terms that should be capitalized are the names of
+products (e.g., Coder).
+
+The exception is **code-server**, which is always lowercase. If it appears at the
+beginning of the sentence, rewrite the sentence to avoid this usage.
+
+### Uncapitalized terms
+
+In general, we do not capitalize the names of features (unless the situation calls for it,
+such as the word appearing at the beginning of a sentence):
+
+- account dormancy
+- audit logs
+- autostart
+- command-line interface
+- dev URLs
+- environment
+- image
+- metrics
+- organizations
+- progressive web app
+- registries
+- single sign-on
+- telemetry
+- workspace
+- workspace providers
+- workspaces as code
+
+We also do not capitalize the names of user roles:
+
+- auditor
+- member
+- site admin
+- site manager
+
+## Standardized spellings
+
+- WiFi
+
