+# lazygit [![Go Report Card](https://goreportcard.com/badge/github.com/jesseduffield/lazygit)](https://goreportcard.com/report/github.com/jesseduffield/lazygit)
+
+A simple terminal UI for git commands, written in Go with the [gocui](https://github.com/jroimartin/gocui "gocui") library.
+
+Are YOU tired of typing every git command directly into the terminal, but you're
+too stubborn to use Sourcetree because you'll never forgive Atlassian for making
+Jira? This is the app for you!
+
+
+![Gif](https://image.ibb.co/mmeXho/optimisedgif.gif)
+
+  * [Installation](https://github.com/jesseduffield/lazygit#installation)
+  * [Usage](https://github.com/jesseduffield/lazygit#usage),
+    [Keybindings](https://github.com/jesseduffield/lazygit/blob/master/docs/Keybindings.md)
+  * [Cool Features](https://github.com/jesseduffield/lazygit#cool-features)
+  * [Contributing](https://github.com/jesseduffield/lazygit#contributing)
+  * [Video Tutorial](https://www.youtube.com/watch?v=VDXvbHZYeKY)
+  * [Twitch Stream](https://www.twitch.tv/jesseduffield)
+
+## Installation
+
+### Homebrew
+```sh
+brew tap jesseduffield/lazygit
+brew install lazygit
+```
+
+### Ubuntu
+Packages for Ubuntu 16.04, 18.04 and 18.10 are available via [Launchpad PPA](https://launchpad.net/~lazygit-team).
+
+**Release builds**
+
+Built from git tags. Supposed to be more stable.
+
+```sh
+sudo add-apt-repository ppa:lazygit-team/release
+sudo apt-get update
+sudo apt-get install lazygit
+```
+
+**Daily builds**
+
+Built from master branch once in 24 hours (or more sometimes).
+
+```sh
+sudo add-apt-repository ppa:lazygit-team/daily
+sudo apt-get update
+sudo apt-get install lazygit
+```
+
+### Void Linux
+Packages for Void Linux are available in the distro repo
+
+They follow upstream latest releases
+
+```sh
+sudo xbps-install -S lazygit
+```
+
+### Arch Linux
+Packages for Arch Linux are available via AUR (Arch User Repository).
+
+There are two packages. The stable one which is built with the latest release
+and the git version which builds from the most recent commit.
+
+  * Stable: https://aur.archlinux.org/packages/lazygit/
+  * Development: https://aur.archlinux.org/packages/lazygit-git/
+
+Instruction of how to install AUR content can be found here:
+https://wiki.archlinux.org/index.php/Arch_User_Repository
+
+### Binary Release (Windows/Linux/OSX)
+You can download a binary release [here](https://github.com/jesseduffield/lazygit/releases).
+
+### Go
+```sh
+go get github.com/jesseduffield/lazygit
+```
+
+Please note:
+If you get an error claiming that lazygit cannot be found or is not defined, you
+may need to add `~/go/bin` to your $PATH (MacOS/Linux), or `%HOME%\go\bin`
+(Windows). Not to be mistaked for `C:\Go\bin` (which is for Go's own binaries,
+not apps like Lazygit).
+
+## Usage
+Call `lazygit` in your terminal inside a git repository. If you want, you can
+also add an alias for this with `echo "alias lg='lazygit'" >> ~/.zshrc` (or
+whichever rc file you're using).
+
+  * Basic video tutorial [here](https://www.youtube.com/watch?v=VDXvbHZYeKY).
+  * List of keybindings
+[here](https://github.com/jesseduffield/lazygit/blob/master/docs/Keybindings.md).
+
+## Cool features
+  * Adding files easily
+  * Resolving merge conflicts
+  * Easily check out recent branches
+  * Scroll through logs/diffs of branches/commits/stash
+  * Quick pushing/pulling
+  * Squash down and rename commits
+
+### Resolving merge conflicts

+### Viewing commit diffs

+
+## Milestones
+- [x] Easy Installation (homebrew, release binaries)
+- [ ] Configurable Keybindings
+- [ ] Configurable Color Themes
+- [ ] Spawning Subprocesses (help needed - have a look at https://github.com/jesseduffield/lazygit/pull/18)
+- [ ] Maintainability
+- [ ] Performance
+- [ ] i18n
+
+## Contributing
+We love your input! Please check out the [contributing guide](CONTRIBUTING.md).

+
+## Work in progress
+This is still a work in progress so there's still bugs to iron out and as this
+is my first project in Go the code could no doubt use an increase in quality,
+but I'll be improving on it whenever I find the time. If you have any feedback
+feel free to [raise an issue](https://github.com/jesseduffield/lazygit/issues)/[submit a PR](https://github.com/jesseduffield/lazygit/pulls).
