 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!
+Rant time: You've heard it before, git is _powerful_, but what good is that power when everything is so damn hard to do? Interactive rebasing requires you to edit a goddamn TODO file in your editor? *Are you kidding me?* To stage part of a file you need to use a command line program to step through each hunk and if a hunk can't be split down any further but contains code you don't want to stage, you have to edit an arcane patch file _by hand_? *Are you KIDDING me?!* Sometimes you get asked to stash your changes when switching branches only to realise that after you switch and unstash that there weren't even any conflicts and it would have been fine to just checkout the branch directly? *YOU HAVE GOT TO BE KIDDING ME!*
 
+If you're a mere mortal like me and you're tired of hearing how powerful git is when in your daily life it's a powerful pain in your ass, lazygit might be for you.

+Call `lazygit` in your terminal inside a git repository.
+
+```sh

+
+If you want, you can
 also add an alias for this with `echo "alias lg='lazygit'" >> ~/.zshrc` (or
 whichever rc file you're using).

-[here](/docs/Keybindings.md).
+### Keybindings
+
+You can check out the list of keybindings [here](/docs/keybindings).
+
+### Changing Directory On Exit
+
+If you change repos in lazygit and want your shell to change directory into that repo on exiting lazygit, add this to your `~/.zshrc` (or other rc file):
+
+```
+lg()
+{
+    export LAZYGIT_NEW_DIR_FILE=~/.lazygit/newdir
+
+    lazygit "$@"
+
+    if [ -f $LAZYGIT_NEW_DIR_FILE ]; then
+            cd "$(cat $LAZYGIT_NEW_DIR_FILE)"
+            rm -f $LAZYGIT_NEW_DIR_FILE > /dev/null
+    fi
+}
+```
+
+Then `source ~/.zshrc` and from now on when you call `lg` and exit you'll switch directories to whatever you were in inside lazyigt. To override this behaviour you can exit using `shift+Q` rather than just `q`.

 ## 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).

+
+## Custom pull request URLs
+
+Some git provider setups (e.g. on-premises GitLab) can have distinct URLs for git-related calls and
+the web interface/API itself. To work with those, Lazygit needs to know where it needs to create
+the pull request. You can do so on your `config.yml` file using the following syntax:
+
+```yaml
+services:
+  "<gitDomain>": "<provider>:<webDomain>"
+```
+
+Where:
+
+- `gitDomain` stands for the domain used by git itself (i.e. the one present on clone URLs), e.g. `git.work.com`
+- `provider` is one of `github`, `bitbucket` or `gitlab`
+- `webDomain` is the URL where your git service exposes a web interface and APIs, e.g. `gitservice.work.com`

+## Predefined commit message prefix
+In situations where certain naming pattern is used for branches and commits, pattern can be used to populate
+commit message with prefix that is parsed from the branch name.
+
+Example:
+* Branch name: feature/AB-123
+* Commit message: [AB-123] Adding feature
+
+```yaml
+  git:
+    commitPrefixes:
+      my_project: # This is repository folder name
+        pattern: "^\\w+\\/(\\w+-\\w+)"
+        replace: "[$1] "

+# Custom Pagers
+
+Lazygit supports custom pagers, [configured](/docs/Config.md) in the config.yml file (which can be opened by pressing `o` in the Status panel).
+
+Support does not extend to Windows users, because we're making use of a package which doesn't have Windows support.
+
+## Default:
+
+```yaml
+git:
+  paging:
+    colorArg: always
+    useConfig: false
+```
+
+the `colorArg` key is for whether you want the `--color=always` arg in your `git diff` command. Some pagers want it set to `always`, others want it set to `never`.
+
+## Delta:
+
+```yaml
+git:
+  paging:
+    colorArg: always
+    pager: delta --dark --paging=never --24-bit-color=never
+```
+
+![](https://i.imgur.com/QJpQkF3.png)
+
+## Diff-so-fancy
+
+```yaml
+git:
+  paging:
+    colorArg: always
+    pager: diff-so-fancy
+```
+
+![](https://i.imgur.com/rjH1TpT.png)
+
+## ydiff
+
+```yaml
+gui:
+  sidePanelWidth: 0.2 # gives you more space to show things side-by-side
+git:
+  paging:
+    colorArg: never
+    pager: ydiff -p cat -s --wrap --width={{columnWidth}}
+```
+
+![](https://i.imgur.com/vaa8z0H.png)
+
+Be careful with this one, I think the homebrew and pip versions are behind master. I needed to directly download the ydiff script to get the no-pager functionality working.
+
+## Using git config
+
+```yaml
+git:
+  paging:
+    colorArg: always
+    useConfig: true
+```
+
+If you set `useConfig: true`, lazygit will use whatever pager is specified in `$GIT_PAGER`, `$PAGER`, or your *git config*. If the pager ends with something like ` | less` we will strip that part out, because less doesn't play nice with our rendering approach. If the custom pager uses less under the hood, that will also break rendering (hence the `--paging=never` flag for the `delta` pager).

+# Undo/Redo in lazygit
+
+![Gif](/docs/resources/undo2.gif)
+
+## Keybindings:
+'z' to undo, 'ctrl+z' to redo
+
+## How it works
+
+If you're as clumsy as me you'll probably have felt the pain of botching an interactive rebase or doing a hard reset onto the wrong commit. Luckily, the reflog allows you to trace your steps and make things right again, but I personally can't stand trying to make sense of the reflog.
+
+Lazygit can read through your reflog for you and walk back action by action so that you don't even need to read the reflog. If lazygit finds a reflog entry where you checked out a branch, we'll checkout the original branch. If the entry is from a commit being applied, we'll go back to the commit before that. If we hit an interactive rebase, we'll go back to the commit you were on just before you started it.
+
+## You can even undo things you did outside of lazygit!
+
+Because lazygit just uses the reflog to keep track of things, it doesn't matter whether you're trying to undo something you did in lazygit or directly on the command line. You can open lazygit for the first time and start undoing thing in your repo! Likewise, lazygit marks its undos/redos in the reflog so if you quit the application and come back, lazygit still knows where you're up to.
+
+## Limitations
+
+There are limitations: firstly, lazygit can only undo things that are recorded in the reflog. That means changes to your working tree or stash aren't covered. Secondly, anything permanent you do like pushing to a remote can't be undone. Thirdly, actions like creating a branch won't be undone, because they're not stored in the reflog.
+
+If you are mid-rebase, undo/redo is not supported, because the reflog doesn't enough contain information about what specific things have happened inside that rebase. If you want to undo out of a rebase, it's best to abort the rebase (the default keybinding for bringing up rebase options is 'm').
+
+Undo/Redo is a new feature so if you find a bug let us know. The worst case scenario is that you'll just need to look at your reflog and manually put yourself back on track.
