+Before reporting a bug, you should try stripping down your Vim configuration
+and removing other plugins.  The sad truth about VimScript is that it is
+fraught with incompatibilities waiting to happen.  I'm happy to work around
+them where I can, but it's up to you to isolate the conflict.
+
+Fugitive is particularly prone to regressions due to Git version issues,
+platform issues, and interactions with other plugins.  I end up bisecting a
+lot more than other projects, and thus I'm especially meticulous here about
+maintaining a clean, readable, history.  Squash and force push any requested
+changes to a pull request.  And if your [commit message
+sucks](https://commit.style), I'm not going to accept it.  Period.
+
+If your contribution involves adding a configuration option, you are going to
+need a very compelling justification for it.  Options add a maintenance
+burden, support burden, and documentation bloat, and oftentimes can be
+achieved much more simply with a custom map or autocommand.  If your option
+controls an underlying Git command, ask yourself why Git itself does not offer
+such configuration.
+
+Beyond that, don't be shy about asking before patching.  What takes you hours
+might take me minutes simply because I have both domain knowledge and a
+perverse knowledge of VimScript so vast that many would consider it a symptom
+of mental illness.  On the flip side, some ideas I'll reject no matter how
+good the implementation is.  "Send a patch" is an edge case answer in my book.

+## Installation
+
+If you don't have a preferred installation method, one option is to install
+[pathogen.vim](https://github.com/tpope/vim-pathogen), and then copy
+and paste:
+
+    cd ~/.vim/bundle
+    git clone https://github.com/tpope/vim-fugitive.git
+    vim -u NONE -c "helptags vim-fugitive/doc" -c q
+
+If your Vim version is below 7.2, I recommend also installing
+[vim-git](https://github.com/tpope/vim-git) for syntax highlighting and
+other Git niceties.
+
+## FAQ
+
+> Why don't any of the commands exist?
+
+Fugitive cares about the current file, not the current working directory.
+Edit a file from the repository.  To avoid the blank window problem, favor
+commands like `:split` and `:tabedit` over commands like `:new` and `:tabnew`.
+
+> Here's a patch that automatically opens the quickfix window after
+> `:Ggrep`.
+
+This is a great example of why I recommend asking before patching.
+There are valid arguments to be made both for and against automatically
+opening the quickfix window.  Whenever I have to make an arbitrary
+decision like this, I ask what Vim would do.  And Vim does not open a
+quickfix window after `:grep`.
+
+Luckily, it's easy to implement the desired behavior without changing
+fugitive.vim.  The following autocommand will cause the quickfix window
+to open after any grep invocation:
+
+    autocmd QuickFixCmdPost *grep* cwindow

 INTRODUCTION                                    *fugitive*
 
-Install in ~/.vim, or in ~\vimfiles if you're on Windows and feeling lucky.
-Vim 7.2 is recommended as it ships with syntax highlighting for many Git file
-types.
-
-If you're in a hurry to get started, here are some things to try:
-
-In any file in your repository, run |:Gedit| HEAD.  Press <CR> to jump to the
-current branch.  Press <CR> again to jump to the top most commit.  Keep using
-<CR> to explore parent commits, trees, and blobs.  Use C in a tree or blob to
-get back to the commit.
-
-Edit a file in the work tree and make some changes.  Use |:Gdiff| to open up
-the indexed version.  Use |do| and |dp| on various hunks to bring the files in
-sync, or use |:Gread| to pull in all changes.  Write the indexed version to
-stage the file.
-
-Run |:Gstatus| to check your repository's status.  Use "-" to stage and reset
-files and "p" to add/reset --patch them.  Invoke |:Gcommit| to commit your
-changes.
-
-Run |:Gblame| in a work tree file to see a blame in a vertical split.  Press
-<CR> on any line to reopen and reblame that file as it stood in that commit.
-Press o or O on any line to inspect that commit in a split or a tab.
-
-Run |:Ggrep| to search the work tree or history.  Run |:Gmove| to rename a
-file.  Run |:Gremove| to delete a file.
+Whenever you edit a file from a Git repository, a set of commands is defined
+that serve as a gateway to Git.
