You must make the best technical documentation tool investments to host your documentation to offer the best user experience for your software. It will not be suitable to simply create a Google Drive folder and expect that to accomplish the task because your software is too complex for such a solution.

For users to understand how the software functions and what it can be used for, there needs to be clear documentation. This is where the best free documentation tools come in.

What is Software Documentation?

Software documentation is an online source that offers comprehensive details about your software, including its features, functionality, operations, and use cases. Thanks to the carefully organized and highly searchable document, users can quickly locate all the information they require.

The documentation includes written text, flowcharts, diagrams, and videos demonstrating each process step. It also offers troubleshooting advice to help users use your software product to its full potential.

Benefits of Software Documentation

SaaS companies should implement software documentation as a powerful strategy to maintain happy customers and highly effective internal teams. Using software documentation can benefit your company in a wide range of ways.

Let us examine the most notable ones:

Reduce errors

Errors are inevitable when humans are involved in a process. The good news is that thorough software documentation can help you reduce mistakes and guarantee flawless results.

The steps outlined in the documentation will be followed precisely when every team member can access the same information. This improves team accountability and brings consistency to how a software development process is carried out.

Enables New Developer Onboarding

It takes a lot of time and effort to onboard new developers and acquaint them with your software development process. You can onboard new developers to the team by giving them simple access to all the technical information and training materials required in an internal software document.

Software documentation instructs novice programmers on all crucial features of your software, including how it was created, the steps it went through, and even the parties involved in the development process. This enables them to grasp your current procedures quickly.

Reduces Support Tickets

Customer-focused software documentation can significantly reduce the number of support tickets you receive. Customers can instantly obtain all the assistance they require whenever they encounter problems with your product because it is a highly searchable document.

Customers are discouraged from filing tickets for trivial concerns due to the simple convenience of handling problems as they happen. This lowers the number of tickets submitted to your internal support team.

Offer customers in-app assistance.

With software documentation, you can give users immediate in-app assistance within the software itself. Modern software documentation tools provide an in-app help widget where you can show help documents and customers how your software functions.  Customers can quickly search for advice while using your software and consult the instructions. This helps them stay on the right track and closer to their goals.
