+# gsh : The Missing Host Manager
+
+`gsh` intends to offer a new way to manage sets of hosts and a collection of accompanying scripts and files.
+You can organize your inventory of hosts with groups and labels. You can add scripts and files (like configs) to your inventory. Then, `gsh` works over ssh, and you can execute scripts and/or copy files en masse to your groups of servers.
+See TODO section below for future plans.
+
+### Requirements
+
+This should work on any linux host, like your workstation. Mac os builds are being tested.
+Access to some ssh servers is needed to use all the features of `gsh`. Currently only bash is supported, with plans for more languages.
+
+### Installation
+
+#### A) Use Go Install
+To build with go install:
+```bash
+$ go install github.com/cbluth/gsh
+```
+
+#### B) Clone via git, and build in docker
+
+To build in docker, golang not need to be installed:
+```bash
+$ git clone https://github.com/cbluth/gsh && cd gsh
+$ ./build.sh    # this will make a `release.tgz` file
+$ tar -xzvf release.tgz # makes linux and mac builds
+$ sudo cp ./build/gsh-linux /usr/local/bin/gsh
+$ sudo chmod a+rx /usr/local/bin/gsh
+```
+
+#### C) Clone via git, and build locally
+
+
+To build with go build:
+```bash
+$ git clone https://github.com/cbluth/gsh && cd gsh
+$ go build . -o gsh
+$ sudo cp gsh /usr/local/bin/gsh
+$ sudo chmod a+rx /usr/local/bin/gsh
+```
+
+## How To Use It??
+
+You can use `gsh` to execute scripts over ssh, and manage an inventory of servers.<br />
+For usage, see [the docs](docs/)
+
+## Hack or Contribute
+This project intentionally avoids importing 3rd party libraries, and tries to stick to the basic libraries provided by golang.
+All contributions and bug reports are welcome, please just open an issue on the github issues page.
+This is a new project, with lots of issues, if you see any bugs, please report them! :)
+
+To hack on this project, git clone to anywhere, and edit the code directly.
+After applying edits to the codebase, you can use `./gsh.sh` to compile and run `gsh` via go, with the same arguments as running the program normally; eg: `./gsh.sh make host dev0 address=dev0.local`
