-# bash/zsh git prompt support
-#
-# Copyright (C) 2006,2007 Shawn O. Pearce <spearce@spearce.org>
-# Distributed under the GNU General Public License, version 2.0.
-#
-# This script allows you to see repository status in your prompt.
-#
-# To enable:
-#
-#    1) Copy this file to somewhere (e.g. ~/.git-prompt.sh).
-#    2) Add the following line to your .bashrc/.zshrc:
-#        source ~/.git-prompt.sh
-#    3a) Change your PS1 to call __git_ps1 as
-#        command-substitution:
-#        Bash: PS1='[\u@\h \W$(__git_ps1 " (%s)")]\$ '
-#        ZSH:  setopt PROMPT_SUBST ; PS1='[%n@%m %c$(__git_ps1 " (%s)")]\$ '
-#        the optional argument will be used as format string.
-#    3b) Alternatively, for a slightly faster prompt, __git_ps1 can
-#        be used for PROMPT_COMMAND in Bash or for precmd() in Zsh
-#        with two parameters, <pre> and <post>, which are strings
-#        you would put in $PS1 before and after the status string
-#        generated by the git-prompt machinery.  e.g.
-#        Bash: PROMPT_COMMAND='__git_ps1 "\u@\h:\w" "\\\$ "'
-#          will show username, at-sign, host, colon, cwd, then
-#          various status string, followed by dollar and SP, as
-#          your prompt.
-#        ZSH:  precmd () { __git_ps1 "%n" ":%~$ " "|%s" }
-#          will show username, pipe, then various status string,
-#          followed by colon, cwd, dollar and SP, as your prompt.
-#        Optionally, you can supply a third argument with a printf
-#        format string to finetune the output of the branch status
-#
-# The repository status will be displayed only if you are currently in a
-# git repository. The %s token is the placeholder for the shown status.
-#
-# The prompt status always includes the current branch name.
-#
-# In addition, if you set GIT_PS1_SHOWDIRTYSTATE to a nonempty value,
-# unstaged (*) and staged (+) changes will be shown next to the branch
-# name.  You can configure this per-repository with the
-# bash.showDirtyState variable, which defaults to true once
-# GIT_PS1_SHOWDIRTYSTATE is enabled.
-#
-# You can also see if currently something is stashed, by setting
-# GIT_PS1_SHOWSTASHSTATE to a nonempty value. If something is stashed,
-# then a '$' will be shown next to the branch name.
-#
-# If you would like to see if there're untracked files, then you can set
-# GIT_PS1_SHOWUNTRACKEDFILES to a nonempty value. If there're untracked
-# files, then a '%' will be shown next to the branch name.  You can
-# configure this per-repository with the bash.showUntrackedFiles
-# variable, which defaults to true once GIT_PS1_SHOWUNTRACKEDFILES is
-# enabled.
-#
-# If you would like to see the difference between HEAD and its upstream,
-# set GIT_PS1_SHOWUPSTREAM="auto".  A "<" indicates you are behind, ">"
-# indicates you are ahead, "<>" indicates you have diverged and "="
-# indicates that there is no difference. You can further control
-# behaviour by setting GIT_PS1_SHOWUPSTREAM to a space-separated list
-# of values:
-#
-#     verbose       show number of commits ahead/behind (+/-) upstream
-#     name          if verbose, then also show the upstream abbrev name
-#     legacy        don't use the '--count' option available in recent
-#                   versions of git-rev-list
-#     git           always compare HEAD to @{upstream}
-#     svn           always compare HEAD to your SVN upstream
-#
-# You can change the separator between the branch name and the above
-# state symbols by setting GIT_PS1_STATESEPARATOR. The default separator
-# is SP.
-#
-# By default, __git_ps1 will compare HEAD to your SVN upstream if it can
-# find one, or @{upstream} otherwise.  Once you have set
-# GIT_PS1_SHOWUPSTREAM, you can override it on a per-repository basis by
-# setting the bash.showUpstream config variable.
-#
-# If you would like to see more information about the identity of
-# commits checked out as a detached HEAD, set GIT_PS1_DESCRIBE_STYLE
-# to one of these values:
-#
-#     contains      relative to newer annotated tag (v1.6.3.2~35)
-#     branch        relative to newer tag or branch (master~4)
-#     describe      relative to older annotated tag (v1.6.3.1-13-gdd42c2f)
-#     tag           relative to any older tag (v1.6.3.1-13-gdd42c2f)
-#     default       exactly matching tag
-#
-# If you would like a colored hint about the current dirty state, set
-# GIT_PS1_SHOWCOLORHINTS to a nonempty value. The colors are based on
-# the colored output of "git status -sb" and are available only when
-# using __git_ps1 for PROMPT_COMMAND or precmd.
-#
-# If you would like __git_ps1 to do nothing in the case when the current
-# directory is set up to be ignored by git, then set
-# GIT_PS1_HIDE_IF_PWD_IGNORED to a nonempty value. Override this on the
-# repository level by setting bash.hideIfPwdIgnored to "false".

+## 開発ガイドライン
+
+1. **変更を加える前に**:
+   - 既存の設定ファイルのバックアップを作成
+   - コミット前にローカルで変更をテスト
+
+2. **シンボリックリンク管理**:
+   - すべての設定ファイルは ~/dotfiles/ からのシンボリックリンクを使用
+   - 編集前にリンクが正しく作成されていることを確認
+
+3. **Vimプラグイン管理**:
+   - プラグインはdein.vimで管理
+   - プラグインディレクトリ: ~/dotfiles/_vim/dein/
+   - プラグイン追加方法: _vimrc内のdein#add()呼び出しを編集
+
+4. **Gitワークフロー**:
+   - 効率化のため設定済みgitエイリアスを使用
+   - 履歴確認には視覚的なlogコマンドを活用
+   - リベース時の自動stashが有効化されています

-# bash completion support for core Git.
-#
-# Copyright (C) 2006,2007 Shawn O. Pearce <spearce@spearce.org>
-# Conceptually based on gitcompletion (http://gitweb.hawaga.org.uk/).
-# Distributed under the GNU General Public License, version 2.0.
-#
-# The contained completion routines provide support for completing:
-#
-#    *) local and remote branch names
-#    *) local and remote tag names
-#    *) .git/remotes file names
-#    *) git 'subcommands'
-#    *) tree paths within 'ref:path/to/file' expressions
-#    *) common --long-options
-#
-# To use these routines:
-#
-#    1) Copy this file to somewhere (e.g. ~/.git-completion.sh).
-#    2) Added the following line to your .bashrc:
-#        source ~/.git-completion.sh
-#
-#    3) Consider changing your PS1 to also show the current branch:
-#        PS1='[\u@\h \W$(__git_ps1 " (%s)")]\$ '
-#
-#       The argument to __git_ps1 will be displayed only if you
-#       are currently in a git repository.  The %s token will be
-#       the name of the current branch.
-#
-#       In addition, if you set GIT_PS1_SHOWDIRTYSTATE to a nonempty
-#       value, unstaged (*) and staged (+) changes will be shown next
-#       to the branch name.  You can configure this per-repository
-#       with the bash.showDirtyState variable, which defaults to true
-#       once GIT_PS1_SHOWDIRTYSTATE is enabled.
-#
-#       You can also see if currently something is stashed, by setting
-#       GIT_PS1_SHOWSTASHSTATE to a nonempty value. If something is stashed,
-#       then a '$' will be shown next to the branch name.
-#
-#       If you would like to see if there're untracked files, then you can
-#       set GIT_PS1_SHOWUNTRACKEDFILES to a nonempty value. If there're
-#       untracked files, then a '%' will be shown next to the branch name.
-#
-# To submit patches:
-#
-#    *) Read Documentation/SubmittingPatches
-#    *) Send all patches to the current maintainer:
-#
-#       "Shawn O. Pearce" <spearce@spearce.org>
-#
-#    *) Always CC the Git mailing list:
-#
-#       git@vger.kernel.org
