1. Put your .gitconfig file and .ssh directory with this Dockerfile

   If you don't want this feature, please remove coresponding lines.

2. Build image

   docker build -t (tag name you want) .

   I use neovim as an example tag for the next step.

   If you remove -t tag part, you need to give coresponding image index.

3. Create a docker machine with this image

   docker run -ti -v /some/dir/you/want/to/work/on:/work_space neovim

   or, if you are using M$

   docker run -ti -v C:/Users/you/dir/you/want/to/work/on:/work_space neovim

   Your directory will be mounted to /work_space.

   Add --rm if you don't want to keep your settings in the docker machine.
