10 Must‑Have Features Every SaaS Documentation Needs

15 Apr, 2026

Introduction

One of the most sought-after features that helps any SaaS grow quickly is proper documentation. There are many platforms (for instance, WordPress, Hugo, and more) that you can use to quickly create documentation for your Saas, but most of these platforms don't present your documentation well. In a SaaS, you're targetting end-users who access your platform via web interfaces, mobile applications, and APIs. In that case, you must find a content management system (CMS) that displays your documentation well. Remember, using the right platform accelerates customer onboarding by a very big margin.

In this guide, I'll focus on the 10 must‑have features every SaaS documentation needs.

1. Format your Guides in Markdown

In the recent years, most companies publish their docs using the markdown format. This format has now become the de facto standard for publishing technical content, documentation, and even blogs. If your company has not adopted this standard, it's high time that you start training your staff to make the switch. Markdown is simple, portable, and readable, enabling fast writing, easy version control, and seamless publishing across platforms.

One way to style the documents in markdown is using the markdown library for Python and linking the Python code to a PostgreSQL database. Then, you can use Jinja templates and Fast API to render the documents in HTML templates formatted with CSS or Bootstrap.

2. Use Syntax Highlighting and Code Lexers

In most cases, a SaaS must show developers how to integrate their solution with common programming languages. Therefore, in the documentation, using code blocks is inevitable. Plain source code without syntax highlighting isn't just confusing, but it might not catch the eyes of your target developers. Also, ensure your code blocks clearly show the programming language with the correct lexer as shown in the following Python code block.

def add_numbers(a, b):
    """Return the sum of two numbers."""
    return a + b

# Example usage
num1 = 5
num2 = 7
result = add_numbers(num1, num2)
print("The sum is:", result)

Also, ensure that every code block has a copy button as shown above. Developers want a copy-and-paste solution when implementing your product to save time and minimize bugs.

3. Present Comparisons Clearly with Tables

Even with proper documentation, you shouldn't always use plain text and paragraphs to present information that needs comparison. For instance, if you're in the VPS industry and you want to list your plans in a document, a table emphasizes information better. The same case applies to backup solutions, managed databases, and more. Here is a sample table that you might include in your documentation to display the right VPS comparison information to your target audience.

4. Highlight Important Information with Admonitions

When writing documentation for your SaaS, you should use admonitions to highlight important information such as warnings, notes, and tips. Admonitions help your audience make the appropriate decisions without making mistakes or poor decisions. Here are some of the most common admonition styles that you should incorporate in your SaaS documentation.

Also, if you anticipate your audience have questions that require direct answers, use a library like pymdownx.details to create FAQs. The library helps you create collapsible FAQ‑style sections as shown below:

5. Incorporate Tabbed Sections

When displaying related information for different environments, tabbed sections work better instead of headings or lists. For instance, the following sample tabs show a well-formated tabbed section highlighting different installation commands for Windows, Mac, and Linux.

$ npm install myapp

$ brew install myapp

$ sudo apt install myapp

6. Adopt Highlighted Placeholders or Inline Code Annotations

Every developer is different, some have sharp minds, and others are just starting their programming journey. If you must provide code blocks, use highlighted placeholders so that developers can clearly see the part they should change to make the code work. The placeholders may include variables such as, database credentials, API keys, and more. For instance, in the following Python and Curl code blocks, it's clear that the user must change some credentials before running the code.

curl -X POST "https://api.example.com/v1/data" \
-H "Authorization: Bearer <YOUR_API_KEY>" \
-d '{"user":"YOUR_USERNAME"}'

import psycopg2
from psycopg2 import sql

def connect_to_db():
    try:

        connection = psycopg2.connect(
            dbname="your_database",
            user="your_username",
            password="your_password",
            host="localhost",
            port="5432"
        )

        cursor = connection.cursor()


        cursor.execute("SELECT version();")
        db_version = cursor.fetchone()
        print("Connected to:", db_version)


        cursor.close()
        connection.close()

    except Exception as e:
        print("Error connecting to database:", e)

# Run the function
connect_to_db()

7. Provide Documentation Ports for Multiple Operating Systems

Technology changes very fast and each day, companies release LTS variants of their different operating systems. This means a command that used to work in version X may not work in version Y. For instance, if you're targeting the Ubuntu operating system. Write a guide for Ubuntu 22.04 and then add different ports for Ubuntu 24.04 and Ubuntu 26.04. Then, ensure those guides are tied to the same port category and include a select box on each guide to allow the user to select the operating system before reading.

8. Highlight Key Presses and Shortcuts

Most guides require users to press different keys to accomplish a task. One common combination is saving a file using the nano text editor by pressing ctrl, x, y and enter keys. To ensure the keys visibility on your doc, highlight and differentiate the keys from normal text using CSS as shown below;

• Press Ctrl + X, then Y, and Enter.

• Press Ctrl + C to return to the normal terminal prompt.

• Enter Q and press Enter to log out from the database.

9. Implement Documentation Navigation Tree

In a SaaS, there are different kinds of documentation that you should create to cover all end-users. You can have a blog section, single articles, product docs, platform docs, and learning paths. Some of these docs require a multi-level side-bar menu for easier navigation. The menu can be multi-level and should clearly group related guides together. Here is a sample side-bar menu for a SaaS that shows the list items that you should display.

- Offices
    - List
    - View
    - Edit
    - Delete
- Users
    - List
    - View
    - Edit
    - Delete
- Roles
    - List
    - View
    - Edit
    - Delete
- Customers
    - List
    - View
    - Edit        
    - Delete

10. Establish a Consistent Style for Guides

Even with the proper features, poorly written technical guides can push customers away. You should adopt the industry's known style guides to write your guide. While the following list is not exhaustive, it highlights some of the common standards that ensure clarity and consistency.

• Use plain english. Prefer short, familiar words over complex ones.
• Use short sentences and convey one idea per sentence.
• Choose a style like the Chicago Manual of Style and stick to it.
• Use active voice instead of passive voice. For instance, instead of saying "Apache is installed by running the" command sudo apt install apache2", say "Run sudo apt install apache2 to install Apache."
• Write in the second person. Address the reader directly using you (and sometimes your). It makes instructions feel personal and actionable, as if you're speaking straight to the user. Avoid we and I.
• Explain technical jargon like words or phrases used within a specific field (IT, medicine, finance) that outsiders may not understand. For example, instead of, Enable SSL to secure your server., say Enable SSL (Secure Sockets Layer), a protocol that encrypts data between your server and users, to secure your server.
• Ensure lists are parallel. For instance, if the first word in a list starts with a verb, use the same consistency.
• Include a Prerequisite section to ensure the reader knows what they need before testing the steps in the guide.
• Avoid redundancy in sentences. For instance, instead of saying install the app in either Windows or Linux , just say Install the app in Windows or Linux and drop or, since its redundant.
• Avoid proverbs, idioms, and figurative language because they introduce ambiguity. For instance, instead of saying Don't put all your eggs in one basket when configuring backups., simply say Always configure multiple backup destinations to reduce risk.

• Break long related information into a list. Dense paragraphs make it hard for readers to scan and act. Convert related steps, options, or requirements into a bulleted or numbered list. For instance, instead of this long sentence, Before installing Apache you need to update your package index, check your system version, and ensure you have sudo privileges. Then you can run the install command and finally verify the service status, just say:

  • Update your package information index.
  • Check your system version.
  • Esure you have sudo privileges.
  • Run the install command.
  • Verify the service status.

• Minimize abstract nouns that end in ‑ion (like installation, administration, configuration), because they often make writing heavier and less direct. Instead, use the verb form. For instance, replace The installation of Apache should be done before configuration. with a more direct sentence like Install Apache before you configure it.

• Prefer possessive forms or adjectival constructions instead of the clunky the X of Y structure. For instance, instead of The role of the administrator is critical., just say The administrator's role is critical.

• Format time correctly to ensure consistency across the guide. For instance, you can say Run the backup at 00:00 or Run the backup at 12:00 a.m. Choose one format and stick to it throughout your documentation.

• Avoid vague references like it because such references introduce ambiquity. For instance, consider the phrase, After starting the server and installing MySQL, restart it. In that phrase, the reader might wonder, Restart what?, the server, the service, or the whole system?. A better explicit reference should be After starting the server and installing MySQL, restart the MySQL service.

Conclusion

This guide touches about the top 10 most critical features every SaaS documentation needs. If you're working as a technical writer or a developer advocate for a company that requires well-detailed user-facing documentation, implement these features to ensure consistency. Remember, proper documentation with the right quality is key for growing your SaaS business and accelerating customer onboarding.
