 A simple terminal UI for git commands, written in Go with the [gocui](https://github.com/jroimartin/gocui "gocui") library.
 
 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.

+### Prompts
+
+The permitted prompt fields are:
+
+| _field_      | _description_                                                                    | _required_ |

+| type         | one of 'input' or 'menu'                                                         | yes        |
+| title        | the title to display in the popup panel                                          | no         |
+| initialValue | (only applicable to 'input' prompts) the initial value to appear in the text box | no         |
+| options      | (only applicable to 'menu' prompts) the options to display in the menu           | no         |
+
+The permitted option fields are:
+| _field_ | _description_ | _required_ |
+|-----------------|----------------------|-|
+| name | the string which will appear first on the line | no |
+| description | the string which will appear second on the line | no |
+| value | the value that will be stored in `.PromptResponses` if the option is selected | yes |
+
+If an option has no name the value will be displayed to the user in place of the name, so you're allowed to only include the value like so:
+
+```yml
+    prompts:
+      - type: 'menu'
+        title: 'What kind of branch is it?'
+        options:
+          - value: 'feature'
+          - value: 'hotfix'
+          - value: 'release'
+```
+
+### Placeholder values
+
+Your commands can contain placeholder strings using Go's [template syntax](https://jan.newmarch.name/go/template/chapter-template.html). The template syntax is pretty powerful, letting you do things like conditionals if you want, but for the most part you'll simply want to be accessing the fields on the following objects:
+
+```
+SelectedLocalCommit
+SelectedReflogCommit
+SelectedSubCommit
+SelectedFile
+SelectedLocalBranch
+SelectedRemoteBranch
+SelectedRemote
+SelectedTag
+SelectedStashEntry
+SelectedCommitFile
+CheckedOutBranch
+```
+
+To see what fields are available on e.g. the `SelectedFile`, see [here](https://github.com/jesseduffield/lazygit/blob/master/pkg/commands/models/file.go) (all the modelling lives in the same directory). Note that the custom commands feature does not guarantee backwards compatibility (until we hit lazygit version 1.0 of course) which means a field you're accessing on an object may no longer be available from one release to the next. Typically however, all you'll need is `{{.SelectedFile.Name}}`, `{{.SelectedLocalCommit.Sha}}` and `{{.SelectedBranch.Name}}`. In the future we will likely introduce a tighter interface that exposes a limited set of fields for each model.
+
+### Keybinding collisions
+
+If your custom keybinding collides with an inbuilt keybinding that is defined for the same context, only the custom keybinding will be executed. This also applies to the global context. However, one caveat is that if you have a custom keybinding defined on the global context for some key, and there is an in-built keybinding defined for the same key and for a specific context (say the 'files' context), then the in-built keybinding will take precedence. See how to change in-built keybindings [here](https://github.com/jesseduffield/lazygit/blob/master/docs/Config.md#keybindings)
+
+### Debugging
+
+If you want to verify that your command actually does what you expect, you can wrap it in an 'echo' call and set `subprocess: true` so that it doesn't actually execute the command but you can see how the placeholders were resolved. Alternatively you can run lazygit in debug mode with `lazygit --debug` and in another terminal window run `lazygit --logs` to see which commands are actually run
+
+### More Examples
+
+See the [wiki](https://github.com/jesseduffield/lazygit/wiki/Custom-Commands-Compendium) page for more examples, and feel free to add your own custom commands to this page so others can benefit!

+# How To Make And Run Integration Tests For lazygit
+
+Integration tests are located in `test/integration`. Each test will run a bash script to prepare a test repo, then replay a recorded lazygit session from within that repo, and then the resultant repo will be compared to an expected repo that was created upon the initial recording. Each integration test lives in its own directory, and the name of the directory becomes the name of the test. Within the directory must be the following files:
+
+### `test.json`
+
+An example of a `test.json` is:
+
+```
+{ "description": "stage a file and commit the change", "speed": 20 }
+```
+
+The `speed` key refers to the playback speed as a multiple of the original recording speed. So 20 means the test will run 20 times faster than the original recording speed. If a test fails for a given speed, it will drop the speed and re-test, until finally attempting the test at the original speed. If you omit the speed, it will default to 10.
+
+### `setup.sh`
+
+This is a bash script containing the instructions for creating the test repo from scratch. For example:
+
+```
+#!/bin/sh
+
+cd $1
+
+git init
+
+git config user.email "CI@example.com"
+git config user.name "CI"
+
+echo test1 > myfile1
+git add .
+git commit -am "myfile1"
+```
+
+## Running tests
+
+To run all tests
+```
+go test pkg/gui/gui_test.go
+```
+
+To run them in parallel
+```
+PARALLEL=true go test pkg/gui/gui_test.go
+```
+
+To run a single test
+```
+go test pkg/gui/gui_test.go -run /<test name>
+```
+
+To run a test at a certain speed
+```
+SPEED=2 go test pkg/gui/gui_test.go -run /<test name>
+```
+
+To update a snapshot
+```
+UPDATE_SNAPSHOTS=true go test pkg/gui/gui_test.go -run /<test name>
+```
+
+## Creating a new test
+
+To create a new test:
+1) Copy and paste an existing test directory and rename the new directory to whatever you want the test name to be. Update the test.json file's description to describe your test.
+2) Update the `setup.sh` any way you like
+3) If you want to have a config folder for just that test, create a `config` directory to contain a `config.yml` and optionally a `state.yml` file. Otherwise, the `test/default_test_config` directory will be used.
+4) From the lazygit root directory, run:
+```
+RECORD_EVENTS=true go test pkg/gui/gui_test.go -run /<test name>
+```
+5) Feel free to re-attempt recording as many times as you like. In the absence of a proper testing framework, the more deliberate your keypresses, the better!
+6) Once satisfied with the recording, stage all the newly created files: `test.json`, `setup.sh`, `recording.json` and the `expected` directory that contains a copy of the repo you created.
+
+The resulting directory will look like:
+```
+actual/ (the resulting repo after running the test, ignored by git)
+expected/ (the 'snapshot' repo)
+config/ (need not be present)
+test.json
+setup.sh
+recording.json
+```
+
+Feel free to create a hierarchy of directories in the `test/integration` directory to group tests by feature.

 ## Keybindings:
 'z' to undo, 'ctrl+z' to redo
@@ -19,6 +19,6 @@ Because lazygit just uses the reflog to keep track of things, it doesn't matter
 
 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.
