+Follow the commit message guidelines at [commit.style](https://commit.style).
+This is an absolute requirement for my repositories, and doing so proves you
+actually read the contribution guidelines, which makes for a good first
+impression.
+
+Good commit messages imply good commits.  Pull requests should typically be a
+single commit, or for the rare complicated case, a series of atomic commits.
+If I request a change, use `git commit --amend` or `git rebase --interactive`
+and force push to your branch.
+
+For feature requests, don't be shy about proposing it in an issue before
+drafting a patch.  If it's a great idea, I might do it for you.  If it's a
+terrible idea, no patch will change my mind.
+
+The worst ideas are configuration options.  You'll need to provide a great
+justification in order to persuade me to take on the maintenance and support
+burden it will inevitably entail.  See if you can get away with a custom map
+or autocommand instead.

+VIM LICENSE
+
+I)  There are no restrictions on distributing unmodified copies of
+    pathogen.vim except that they must include this license text.  You can
+    also distribute unmodified parts of pathogen.vim, likewise unrestricted
+    except that they must include this license text.  You are also allowed to
+    include executables that you made from the unmodified pathogen.vim
+    sources, plus your own usage examples and Vim scripts.
+
+II) It is allowed to distribute a modified (or extended) version of
+    pathogen.vim, including executables and/or source code, when the following
+    four conditions are met:
+    1) This license text must be included unmodified.
+    2) The modified pathogen.vim must be distributed in one of the following
+       five ways:
+       a) If you make changes to pathogen.vim yourself, you must clearly
+          describe in the distribution how to contact you.  When the
+          maintainer asks you (in any way) for a copy of the modified
+          pathogen.vim you distributed, you must make your changes, including
+          source code, available to the maintainer without fee.  The
+          maintainer reserves the right to include your changes in the
+          official version of pathogen.vim.  What the maintainer will do with
+          your changes and under what license they will be distributed is
+          negotiable.  If there has been no negotiation then this license, or
+          a later version, also applies to your changes. The current
+          maintainer is Bram Moolenaar <Bram@vim.org>.  If this changes it
+          will be announced in appropriate places (most likely vim.sf.net,
+          www.vim.org and/or comp.editors). When it is completely impossible
+          to contact the maintainer, the obligation to send him your changes
+          ceases.  Once the maintainer has confirmed that he has received your
+          changes they will not have to be sent again.
+       b) If you have received a modified pathogen.vim that was distributed as
+          mentioned under a) you are allowed to further distribute it
+          unmodified, as mentioned at I).  If you make additional changes the
+          text under a) applies to those changes.
+       c) Provide all the changes, including source code, with every copy of
+          the modified pathogen.vim you distribute.  This may be done in the
+          form of a context diff.  You can choose what license to use for new
+          code you add.  The changes and their license must not restrict
+          others from making their own changes to the official version of
+          pathogen.vim.
+       d) When you have a modified pathogen.vim which includes changes as
+          mentioned under c), you can distribute it without the source code
+          for the changes if the following three conditions are met:
+          - The license that applies to the changes permits you to distribute
+            the changes to the Vim maintainer without fee or restriction, and
+            permits the Vim maintainer to include the changes in the official
+            version of pathogen.vim without fee or restriction.
+          - You keep the changes for at least three years after last
+            distributing the corresponding modified pathogen.vim.  When the
+            maintainer or someone who you distributed the modified
+            pathogen.vim to asks you (in any way) for the changes within this
+            period, you must make them available to him.
+          - You clearly describe in the distribution how to contact you.  This
+            contact information must remain valid for at least three years
+            after last distributing the corresponding modified pathogen.vim,
+            or as long as possible.
+       e) When the GNU General Public License (GPL) applies to the changes,
+          you can distribute the modified pathogen.vim under the GNU GPL
+          version 2 or any later version.
+    3) A message must be added, at least in the output of the ":version"
+       command and in the intro screen, such that the user of the modified
+       pathogen.vim is able to see that it was modified.  When distributing as
+       mentioned under 2)e) adding the message is only required for as far as
+       this does not conflict with the license used for the changes.
+    4) The contact information as required under 2)a) and 2)d) must not be
+       removed or changed, except that the person himself can make
+       corrections.
+
+III) If you distribute a modified version of pathogen.vim, you are encouraged
+     to use the Vim license for your changes and make them available to the
+     maintainer, including the source code.  The preferred way to do this is
+     by e-mail or by uploading the files to a server and e-mailing the URL. If
+     the number of changes is small (e.g., a modified Makefile) e-mailing a
+     context diff will do.  The e-mail address to be used is
+     <maintainer@vim.org>
+
+IV)  It is not allowed to remove this license from the distribution of the
+     pathogen.vim sources, parts of it or from a modified version.  You may
+     use this license for previous pathogen.vim releases instead of the
+     license that they came with, at your option.

+# pathogen.vim
+
+Manage your `'runtimepath'` with ease.  In practical terms, pathogen.vim
+makes it super easy to install plugins and runtime files in their own
+private directories.
+
+**For new users, I recommend using Vim's built-in package management
+instead.**  `:help packages`
+
+## Installation
+
+Install to `~/.vim/autoload/pathogen.vim`.
+Or copy and paste the following into your terminal/shell:
+
+    mkdir -p ~/.vim/autoload ~/.vim/bundle && \
+    curl -LSso ~/.vim/autoload/pathogen.vim https://tpo.pe/pathogen.vim
+
+If you're using Windows, change all occurrences of `~/.vim` to `~\vimfiles`.
+
+## Runtime Path Manipulation
+
+Add this to your vimrc:
+
+    execute pathogen#infect()
+
+If you're brand new to Vim and lacking a vimrc, `vim ~/.vimrc` and paste
+in the following super-minimal example:
+
+    execute pathogen#infect()
+    syntax on
+    filetype plugin indent on
+
+Now any plugins you wish to install can be extracted to a subdirectory
+under `~/.vim/bundle`, and they will be added to the `'runtimepath'`.
+Observe:
+
+    cd ~/.vim/bundle && \
+    git clone https://github.com/tpope/vim-sensible.git
+
+Now [sensible.vim](https://github.com/tpope/vim-sensible) is installed.
+If you really want to get crazy, you could set it up as a submodule in
+whatever repository you keep your dot files in.  I don't like to get
+crazy.
+
+If you don't like the directory name `bundle`, you can pass a runtime relative
+glob as an argument:
+
+    execute pathogen#infect('stuff/{}')
+
+The `{}` indicates where the expansion should occur.
+
+You can also pass an absolute path instead.  I keep the plugins I maintain under `~/src`, and this is how I add them:
+
+    execute pathogen#infect('bundle/{}', '~/src/vim/bundle/{}')
+
+Normally to generate documentation, Vim expects you to run `:helptags`
+on each directory with documentation (e.g., `:helptags ~/.vim/doc`).
+Provided with pathogen.vim is a `:Helptags` command that does this on
+every directory in your `'runtimepath'`.  If you really want to get
+crazy, you could even invoke `Helptags` in your vimrc.  I don't like to
+get crazy.
+
+Finally, pathogen.vim has a rich API that can manipulate `'runtimepath'`
+and other comma-delimited path options in ways most people will never
+need to do.  If you're one of those edge cases, look at the source.
+It's well documented.
+
+## Native Vim Package Management
+
+Vim 8 includes support for package management in a manner similar to
+pathogen.vim.  If you'd like to transition to this native support,
+pathogen.vim can help.  Calling `pathogen#infect()` on an older version of Vim
+will supplement the `bundle/{}` default with `pack/{}/start/{}`, effectively
+backporting a subset of the new native functionality.
+
+## Runtime File Editing
+
+`:Vopen`, `:Vedit`, `:Vsplit`, `:Vvsplit`, `:Vtabedit`, `:Vpedit`, and
+`:Vread` have all moved to [scriptease.vim][].
+
+[scriptease.vim]: https://github.com/tpope/vim-scriptease
+
+## FAQ
+
+> Can I put pathogen.vim in a submodule like all my other plugins?
+
+Sure, stick it under `~/.vim/bundle`, and prepend the following to your
+vimrc:
+
+    runtime bundle/vim-pathogen/autoload/pathogen.vim
+
+Or if your bundles are somewhere other than `~/.vim` (say, `~/src/vim`):
+
+    source ~/src/vim/bundle/vim-pathogen/autoload/pathogen.vim
+
+> Will you accept these 14 pull requests adding a `.gitignore` for
+> `tags` so I don't see untracked changes in my dot files repository?
+
+No, but I'll teach you how to ignore `tags` globally:
+
+    git config --global core.excludesfile '~/.cvsignore'
+    echo tags >> ~/.cvsignore
+
+While any filename will work, I've chosen to follow the ancient
+tradition of `.cvsignore` because utilities like rsync use it, too.
+Clever, huh?
+
+> What about Vimballs?
+
+If you really must use one:
+
+    :e name.vba
+    :!mkdir ~/.vim/bundle/name
+    :UseVimball ~/.vim/bundle/name
+
+> Why don't my plugins load when I use Vim sessions?
+
+Vim sessions default to capturing all global options, which includes the
+`'runtimepath'` that pathogen.vim manipulates.  This can cause other problems
+too, so I recommend turning that behavior off:
+
+    set sessionoptions-=options
+
+## Contributing
+
+If your [commit message sucks](http://stopwritingramblingcommitmessages.com/),
+I'm not going to accept your pull request.  I've explained very politely
+dozens of times that
+[my general guidelines](http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html)
+are absolute rules on my own repositories, so I may lack the energy to
+explain it to you yet another time.  And please, if I ask you to change
+something, `git commit --amend`.
+
+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 Vim script 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.
+
