+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,
-but that the program is *semantically* not equivalent.
+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 called `pydisasm`.
+
+### 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.

+3.7 or so, including PyPy bytecode and Dropbox's Python 2.5 bytecode.
 
 Why this?
 ---------
 
-There were a number of decompyle, uncompile, uncompyle2, uncompyle3
-forks around. All of them came basically from the same code base, and
-almost all of them no were no longer actively maintained. Only one
-handled Python 3, and even there, only 3.2 or 3.3 depending on which
-code is used. This code pulls these together and moves forward. This
-project has the most complete support for Python 3.3 and above. It
-also addresses a number of open issues in the previous forks.
+Ok, I'll say it: this software is amazing. It is more than your
+normal hacky decompiler. Using compiler_ technology, the program
+creates a parse tree of the program from the instructions; nodes at
+the upper levels that look a little like what might come from a Python
+AST. So we can really classify and understand what's going on in
+sections of Python bytecode.
 
-What makes this different from other CPython bytecode decompilers?: its
-ability to deparse just fragments and give source-code information
-around a given bytecode offset.
+Building on this, another thing that makes this different from other
+CPython bytecode decompilers is the ability to deparse just
+*fragments* of source code and give source-code information around a
+given bytecode offset.
 
-I use this to deparse fragments of code inside my trepan_
-debuggers_. For that, I need to record text fragments for all
-bytecode offsets (of interest). This purpose although largely
-compatible with the original intention is yet a little bit different.
+I use the tree fragments to deparse fragments of code inside my
+trepan_ debuggers_. For that, bytecode offsets are recorded and
+associated with fragments of the source code. This purpose, although
+compatible with the original intention, is yet a little bit different.
 See this_ for more information.
 
-The idea of Python fragment deparsing given an instruction offset can
-be used in showing stack traces or any program that wants to show a
-location in more detail than just a line number.  It can be also used
-when source-code information does not exist and there is just bytecode
-information.
+Python fragment deparsing given an instruction offset is useful in
+showing stack traces and can be encorporated into any program that
+wants to show a location in more detail than just a line number at
+runtime.  This code can be also used when source-code information does
+not exist and there is just bytecode. Again, my debuggers make use of
+this.
+
+There were (and still are) a number of decompyle, uncompyle,
+uncompyle2, uncompyle3 forks around. Almost all of them come basically
+from the same code base, and (almost?) all of them are no longer
+actively maintained. One was really good at decompiling Python 1.5-2.3
+or so, another really good at Python 2.7, but that only. Another
+handles Python 3.2 only; another patched that and handled only 3.3.
+You get the idea. This code pulls all of these forks together and
+*moves forward*. There is some serious refactoring and cleanup in this
+code base over those old forks.
+
+This project has the most complete support for Python 3.3 and above
+and the best all-around Python support.
+
+We are serious about testing, and use automated processes to find
+bugs. In the issue trackers for other decompilers, you will find a
+number of bugs we've found along the way. Very few to none of them are
+fixed in the other decompilers.
