[[!meta title="Reporting an error"]]
In this documentation we use the term *bug* to refer to a software error.
Reporting bugs is a great way of helping us improve Tails.
Remember that **the more effectively you report a bug**, the more likely we are to fix it.
<h1 id="already-known">Check if the bug is already known</h1>
Have a look at:
the [[list of known issues|support/known_issues]]
the [[!tails_gitlab groups/tails/-/milestones desc="list of things that will be fixed or improved in the next release"]]
<h1 id="useful-bug-report">How to write a useful bug report</h1>
The first aim of a bug report is to **tell the developers exactly how to reproduce the failure**, so try to reproduce the issue yourself and describe how you did that.
If that is not possible, try to **describe what went wrong in detail**. Write down the error messages, especially if they have numbers.
Write **clearly and be precise**. Say what you mean, and make sure it cannot be misinterpreted.
Be ready to provide extra information if the developers need it. If they did not need it, they would not be asking for it.
You can also refer to the great [How to Report Bugs Effectively](http://www.chiark.greenend.org.uk/~sgtatham/bugs.html), by Simon Tatham.
