+# How to report a Bug
+
+## The difficulty of the problem
+
+There is no Python decompiler yet, that I know about that will
+decompyle everything. This one probably does the
+best job of *any* Python decompiler. But it is a constant work in progress: Python keeps changing, and so does its code generation.
+
+I have found bugs in *every* Python decompiler I have tried. Even
+those where authors/maintainers claim that they have used it on 
+the entire Python standard library. And I don't mean that
+the program doesn't come out with the same Python source instructions,
+but that the program is *semantically* not equivalent.
+
+So it is likely you'll find a mistranslation in decompiling.
+
+## What to send (minimum requirements)
+
+The basic requirement is pretty simple:
+
+* Python bytecode
+* Source text
+
+## What to send (additional helpful information)
+
+Some kind folks also give the invocation they used and the output
+which usually includes an error message produced. This is helpful. I
+can figure out what OS you are running this on and what version of
+*uncomplye6* was used. Therefore, if you don't provide the input
+command and the output from that, please give:
+
+* _uncompile6_ version used
+* OS that you used this on
+* Python interpreter version used
+
+
+### But I don't *have* the source code!
+
+Sure, I get it. No problem. There is Python assembly code on parse
+errors, so simply by hand decompile that. To get a full disassembly, use pydisasm from the [xdis](https://pypi.python.org/pypi/xdis) package. Opcodes are described in the documentation for the [dis](https://docs.python.org/3.6/library/dis.html) module.
+
+### But I don't *have* the source code and am incapable of figuring how how to do a hand disassembly!
+
+Well, you could learn. No one is born into this world knowing how to disassemble Python bytecode. And as Richard Feynman once said, "What one fool can learn, so can another."
+
+## Narrowing the problem
+
+I don't need the entire source code base for which one file or module
+can't be decompiled. I just need that one file or module only. If
+there are several files, file a bug report for each file.
+
+Python modules can get quite large, and usually decompilation problems
+occur in a single function or maybe the main-line code but not any of
+the functions or classes. So please chop down the source code by
+removing those parts that do to decompile properly.
+
+By doing this, you'll probably have a better sense of what exactly is
+the problem. Perhaps you can find the boundary of what decompiles, and
+what doesn't. That is useful. Or maybe the same file will decompile
+properly on a neighboring version of Python. That is helpful too.
+
+In sum, the more you can isolate or narrow the problem, the more
+likley the problem will be fixed and fixed sooner.
