+This decompiler 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,

+There is no Python decompiler yet that I know about that will
+decompile everything. Overall, I think this one probably does the best
+job of *any* Python decompiler that handles such a wide range of
+versions.
 
-So it is likely you'll find a mistranslation in decompiling.
+But at any given time, there are maybe dozens of valid Python bytecode
+files that I know of that will cause problems. And when I get through
+those and all the issues of decompiler bugs that are currently logged,
+I could probably easily find dozens more bugs just by doing a
+decompile of all the Python bytecode on any one of my
+computers. Unless you want to help out by _fixing_ bugs, or are
+willing to do work by isolating and narrowing bugs, don't feel you are
+doing me a favor by doing scans on your favorite sets of bytecode
+files.
+
+In sum, it is not uncommon that you will find a mistranslation in
+decompiling. Furthermore, you may be expected to do some work in order
+to have your bug worthy of being considered above other bugs.
+
+No one is getting paid to work to work on this project, let alone bugs
+you may have an interest in. If you require decompiling bytecode
+immediately, consider using a decompilation service.
+
+## Is it really a bug?
+
+
+### Do you have valid bytecode?
+
+As mentioned in README.rst, this project doesn't handle obfuscated
+code. See README.rst for suggestions for how to remove some kinds of
+obfuscation.
+
+Checking if bytecode is valid is pretty simple: disassemble the code.
+Python comes with a disassembly module called `dis`. A prerequisite
+module for this package, `xdis` has a cross-python version
+disassembler.
+
+### Semantic equivalence vs. exact source code
+
+Almost all versions of Python can perform some sort of code
+improvement that can't be undone. In earlier versions of Python it is
+rare; in later Python versions, it is more common.
+
+If the code emitted is semantically equivalent, then this isn't a bug.
+
+
+For example the code might be
+
+```
+if a:
+  if b:
+     x = 1
+```
+
+and we might produce:
+
+```
+if a and b:
+  x = 1
+```
+
+These are equivalent. Sometimes
+
+```
+else:
+   if ...
+
+```
+
+may come out as `elif`.
+
+
+As mentioned in the README, It is possible that Python changes what
+you write to be more efficient. For example, for:
+
+
+```
+if True:
+  x = 5
+```
+
+Python will generate code like:
+
+```
+x = 5
+```
+
+So just because the text isn't the same, does not
+necessarily mean there's a bug.
