+# Styleguide
+
+## Writing Principles
+
+A consistent style greatly increases the usability of all documentation and communication.
+
+Use this page as a reference and style guide for our internal and external documentation.
+
+### Knowledge Expectations
+
+**Assume competence, not familiarity.**
+
+Write for someone who knows a great deal — up to but not including this project.
+
+**What readers know:**
+
+- Basic computer operation
+- Command line familiarity
+- General interest in systems configuration
+
+**What readers don't know:**
+
+- NixOS-specific concepts
+- NixOS ecosystem details or grammar
+- NixOS workflows
+
+If specific knowledge is required, mention it at the start of the page.
+
+#### Show, Don't Tell
+
+The fastest path to understanding is a working example.
+People learn by doing, not by reading about doing.
+
+**Recommended structure:**
+
+- Start with the minimal working code or command
+- Briefly explain what it does
+- Cover edge cases or variations
+- Link to further information instead of including it
+
+#### Grammar and Style
+
+**Sentence structure:**
+
+- Use simple, direct sentences
+- Break complex ideas into multiple short sentences
+- Avoid nested clauses
+
+**Bad:**
+
+> The following command, which utilizes nixos-generate-config to produce a comprehensive hardware configuration, will write the results back into the respective configuration directory located on your local machine.
+
+What the user does is hidden in the middle.
+`nixos-generate-config` is a leaked implementation detail.
+Users care about *detecting hardware*, not *the tool that does it*.
+
+**Good:**
+
+> This command detects your hardware and saves the configuration.
+
+#### Content Organization
+
+Lead with value. State what the reader will accomplish before explaining how.
+
+**Bad:**
+
+> To create a new NixOS configuration that you can later use as a webserver, first navigate to your project directory, then add a new host configuration file with the desired machine name.
+
+**Good:**
+
+Add a webserver configuration to your NixOS setup:
+
+```nix
+# hosts/webserver/configuration.nix
+{ ... }:
+{
+  services.nginx.enable = true;
+}
+```
+
+Use **progressive disclosure**. Introduce concepts only when needed.
+
+**Recommended structure:**
+
+1. State the goal (one sentence)
+2. Show the simplest working example
+3. Explain concepts if needed
+4. Provide advanced options separately or link to the reference
+
+#### No Meta-commentary
+
+Don't describe what the documentation does. Just do it.
+
+**Don't:**
+
+> This section explains how to configure networking.
+> The following guide walks you through setting up a web server.
+
+**Do:**
+
+> Configure networking by setting:
+> Set up a web server:
+
+#### Code Examples
+
+**Keep examples focused:**
+
+- Show one concept at a time
+- Use realistic but simple scenarios
+- Avoid dependencies on other examples
+
+**Minimal comments**
+
+Let the code speak for itself.
+Paste code examples directly and without further alteration.
+
+**Bad:**
+
+```nix
+# This sets the hostname for the machine
+{
+  networking.hostName = "webserver"; # Change this to your machine's hostname
+  # This enables SSH access
+  services.openssh.enable = true; # Required for remote deployment
+}
+```
+
+**Good:**
+
+```nix
+{
+  networking.hostName = "webserver";
+  services.openssh.enable = true;
+}
+```
+
+#### Lead with Practical Examples
+
+Don't front-load theory. Readers want to accomplish something first, then understand why it works.
+
+- Show configuration as *what you want*, not *how the module system works*
+- Introduce Nix-specific concepts only when they are needed to complete the task
+- Defer language mechanics to reference pages or `nix.dev`
+
+**Bad:**
+
+> Before adding a service, you need to understand the NixOS module system and attribute set merging.
+
+**Good:**
+
+Enable nginx:
+
+```nix
+{ services.nginx.enable = true; }
+```
+
+This adds nginx to your system configuration. Rebuild to apply:
+
+```bash
+sudo nixos-rebuild switch
+```
+
+#### Teach Nix through examples, not theory
+
+
+Users learn the NixOS module system by seeing patterns first.
+
+- Start with a working example
+- Explanation follows the code
+- Link deeper concepts instead of inlining them
+- Link to `nix.dev` for optional learning
+
+#### General Rules
+
+- Abbreviate keys like `ssh-ed25519 AAAAC3NzaC…`
+- Abbreviate IP addresses like `192.168.XXX.XXX`
+- Variables are capitalized and start with `$`, e.g. `$YOUR_HOSTNAME`
+- Variables should be directly usable during copy-paste
+- Do **not** describe missing code parts (`#elided`, `#omitted`)
+- **Machine vs Host**: use "machine" for the NixOS system identity, "host" for the physical or virtual hardware
+
+#### Capitalization
+
+- GB / RAM / HDD
+- bootable USB drive
+- Wi-Fi / DHCP / DNS
+- macOS / NixOS / Nix / Linux
+- Flakes
+- git
+
+#### Headings
+
+Use sentence case. A reader scanning only headings should understand the page.
+
+**Don't:**
+
+> Getting Started
+> Overview
+> Configure The Database
+
+**Do:**
+
+> Set up a PostgreSQL database
+> Configure networking
+> Add a user to the system
+
+#### Imperative Mood, Voice, and Person
+
+Use imperative mood for instructions. Address the reader as "you", not "the user". Use active voice; in other words, make the subject do the action.
+
+**Don't:**
+
+> The user should run the following command.
+> The configuration will need to be updated.
+> The key is generated by the system.
+
+**Do:**
+
+> Run the command.
+> Update the configuration.
+> The system generates the key.
+
+#### Tense
+
+Use present tense for descriptions. Future tense makes documentation feel tentative.
+
+**Don't:**
+
+> This will create a new folder.
+> Running this command will install the package.
+
+**Do:**
+
+> This creates a new folder.
+> Running this command installs the package.
+
+#### Be Confident
+
+State facts. Don't hedge with "should," "might," "typically," or "usually" unless the behavior genuinely varies.
+
+**Don't:**
+
+> This should create the configuration file.
+> The service will usually start automatically.
+
+**Do:**
+
+> This creates the configuration file.
+> The service starts automatically.
+
+#### Avoid Nominalizations
+
+A nominalization is a verb turned into a noun, often by adding *-tion*, *-meant*, or *-ance* (e.g. "explanation", "selection"). The fix: find the hidden verb and use it directly.
+
+**Don't:**
+
+> Make a selection from the list.
+> Provide an explanation of the error.
+
+**Do:**
+
+> Select from the list.
+> Explain the error.
+
+#### Plain Words
+
+Technical precision for technical terms; plain language for everything else.
+
+- "use" not "utilize"
+- "start" not "initiate"
+- "end" not "terminate"
+- "help" not "facilitate"
+- "send" not "transmit"
+- "set up" not "establish"
+- "find out" not "ascertain"
+
+#### Filler Words and Weak Phrases
+
+Cut words and phrases that add length without meaning.
+
+Delete on sight:
+
+- "simply", "just", "easily", "basically", "obviously"
+- "in order to" → use "to"
+- "allows you to" → use the verb directly
+- "it's worth noting that" → just say the thing
+- no exclamation marks in technical prose
+
+**Don't:**
+
+> Simply run `nixos-rebuild switch`.
+> In order to deploy, you first need to run the command, which allows you to push the config.
+> It's worth noting that this requires root access.
+
+**Do:**
+
+> Run `nixos-rebuild switch`.
+> To deploy, run:
+> This requires root access.
+
+Every word must earn its place.
+
+#### Writing Procedures
+
+One instruction per sentence. Don't pack multiple actions into one sentence.
+
+**Don't:**
+
+> Navigate to your project directory and run the command, then check the output.
+
+**Do:**
+
+1. Navigate to your project directory.
+2. Run the command.
+3. Check the output.
+
+Don't bury the negative. Key limitations should be prominent, not a footnote after a positive description.
+
+**Don't:**
+
+> This service supports multiple roles, integrates with existing modules, and works great for most setups (note that multiple instances are not supported).
+
+**Do:**
+
+> This service does not support multiple instances.
+
+#### Consistent Terminology
+
+Pick a term and stick to it. Don't swap synonyms to avoid repetition. In technical documentation, repetition is clarity.
+
+**Don't:**
+
+> Create a machine... configure the host... deploy the node.
+
+**Do:**
+
+> Create a machine... configure the machine... deploy the machine.
+
+#### Links
+
+Use descriptive link text. Never use "click here" or "this link."
+
+**Don't:**
+
+> For more information, see `[this page](url)`.
+> Click `[here](url)` to read the reference.
+
+**Do:**
+
+> See the `[NixOS options reference](url)` for details.
+> Read the `[NixOS module system guide](url)`.
+
+Only link when the destination is directly relevant, not for generic background context (sometimes known as "Wikipedia-style links"). Readers feel obligated to click links, fearing they'll miss something important. Don't send them to a generic article about a technology when they're looking for how *your* system uses it.
+
+**Don't:**
+
+> Our software uses [SQLite](https://sqlite.org/) for storage.
+> *(Reader clicks expecting schema details — finds a generic product page instead.)*
+
+(Note that in the above example, the SQLite link is the SQLite home page, which is likely not pertinent.)
+
+**Do:**
+
+> See `[database schema](url)` for the full table structure.
+
+#### UI Language
+
+Match UI element names exactly: wording, casing, and spacing (even if a label seems oddly worded).
+
+**Don't:**
+
+> Click the generator button.
+> Select the save option.
+
+**Do:**
+
+> Click **Generate a Key**.
+> Click **Save Changes**.
+
+Someone will go looking for a button labeled "generator." They will not find it. They will be frustrated.
+
+Consistency between documentation and interface builds confidence. Words are part of the interface.
+
+:::{.tip}
+This can be tricky as UI changes; we don't yet have a policy in place for how to handle this. We welcome comments and suggestions.
+:::
+
+#### Clean system discipline
+
+Your machine has things new users don't: cached credentials, installed tools, environment variables, existing configuration. When writing or updating documentation:
+
+**Don't:**
+
+> Write steps from memory on your development machine, assuming what works there will work everywhere.
+
+**Do:**
+
+> - Start on a clean system — a fresh VM or new user account
+> - Take notes in real time as you work through the steps
+> - Document every warning, prompt, or unexpected output the system shows
+
+Also think in combinations: WSL vs native Linux, with and without existing keys. You don't need to test every matrix square — but you need to know which ones diverge.
+
+#### Never type code — always copy-paste
+
+Always copy commands and code from a terminal where you just ran them successfully. Never retype from memory.
+
+**Don't:**
+
+> Retype a command from memory into the documentation.
+> Retype code into a code-block from memory
+
+**Do:**
+
+> Paste commands directly from the shell or IDE.
+> Paste code that has been successfully validated with nix-instantiate or nix-build
+
+Replace sensitive values with placeholders: `<YOUR-KEY>`, `<YOUR-HOST>`, `<YOUR-TOKEN>`.
+
+Typed-from-memory commands introduce subtle errors. Even the most experienced software developers have occasional typos.

+- `boot.loader.systemd-boot` gained support for [Automatic Boot Assessment](https://systemd.io/AUTOMATIC_BOOT_ASSESSMENT/) via the new [`boot.loader.systemd-boot.bootCounting`](#opt-boot.loader.systemd-boot.bootCounting.enable) options, allowing automatic detection of and recovery from bad NixOS generations. As part of this change, boot loader entries on the ESP/XBOOTLDR partition are now named `nixos-<content-hash>.conf` instead of `nixos-generation-<n>.conf`; existing entries are migrated automatically on the next `nixos-rebuild boot`/`switch`.
+
 - The `newuidmap` and `newgidmap` security wrappers are now installed with `cap_setuid`/`cap_setgid` file capabilities instead of the setuid-root bit, matching shadow's `--with-fcaps` install mode and other major distributions. Rootless containers (podman, docker-rootless, unprivileged user namespaces) are unaffected. The only behavioural change is that mapping host uid 0 via `/etc/subuid` (which NixOS never configures by default) additionally requires `cap_setfcap`; users who explicitly grant uid 0 in a subuid range can restore the previous behaviour with `security.wrappers.newuidmap.capabilities = lib.mkForce "cap_setuid,cap_setfcap+ep";`.
