### [eget] インストーラーを使う場合 (クロスプラットフォーム)

``````sh
brew install eget        # Unix-like systems
# or
scoop install eget       # Windows

cd (YOUR-BIN-DIRECTORY)
eget $user/$repo
``````

[eget]: https://github.com/zyedidia/eget

### [scoop] インストーラーを使う場合 (Windowsのみ)

``````
scoop install https://raw.githubusercontent.com/$user/$repo/master/$repo.json
``````

もしくは

``````
scoop bucket add hymkor https://github.com/hymkor/scoop-bucket
scoop install $repo
``````

[scoop]: https://scoop.sh/

### "go install" を使う場合 (要Go言語開発環境)

``````
go install $module$cmddir@latest
``````

``go install`` は ```$HOME/go/bin`` もしくは ```$GOPATH/bin`` へ実行ファイルを導入するので、``$repo`` を実行するにはそのディレクトリを ```$PATH`` に追加する必要があります。

### Use [eget] installer (cross-platform)

``````sh
brew install eget        # Unix-like systems
# or
scoop install eget       # Windows

cd (YOUR-BIN-DIRECTORY)
eget $user/$repo
``````

[eget]: https://github.com/zyedidia/eget

### Use [scoop]-installer (Windows only)

``````
scoop install https://raw.githubusercontent.com/$user/$repo/master/$repo.json
``````

or

``````
scoop bucket add hymkor https://github.com/hymkor/scoop-bucket
scoop install $repo
``````

[scoop]: https://scoop.sh/

### Use "go install" (requires Go toolchain)

``````
go install $module$cmddir@latest
``````

Because ``go install`` introduces the executable into ```$HOME/go/bin`` or ```$GOPATH/bin``, you need to add this directory to your ```$PATH`` to execute ``$repo``.
