+## Installation/removal
+
+You can use the `autorandr.py` script as a stand-alone binary. If you'd like to
+install it as a system-wide application, there is a Makefile included that also
+places some configuration files in appropriate directories such that autorandr
+is invoked automatically when a monitor is connected or removed, the system
+wakes up from suspend, or a user logs into an X11 session.
+
+For Debian-based distributions (including Ubuntu) it is recommended to call
+`make deb` to obtain a package that can be installed and removed with `dpkg`.
+
+On Arch Linux, there is [an aur package
+available](https://aur.archlinux.org/packages/autorandr-git/).
+
+autorandr is also packaged in the [nix package manager](https://nixos.org/nix/)
+repositories.
+
+On other distributions you can install autorandr by calling `make install` and
+remove it by calling `make uninstall`. Run `make` without arguments to obtain a
+list of what exactly will be installed.
+
+We appreciate packaging scripts for other distributions, please file a pull
+request if you write one.
+
+If you prefer `pip` over your package manager, you can install autorandr with:
+
+ sudo pip install "git+http://github.com/phillipberndt/autorandr#egg=autorandr"
+
+or simply
+
+ sudo pip install autorandr
+
+if you prefer to use a stable version.
+
+Automatically generated packages versions are available from the
+[openSUSE build service](https://build.opensuse.org/package/show/home:phillipberndt/autorandr).
## How to use
Save your current display configuration and setup with:
-```
-autorandr --save mobile
-```
+
+ autorandr --save mobile
Connect an additional display, configure your setup and save it:
-```
-autorandr --save docked
-```
+
+ autorandr --save docked
Now autorandr can detect which hardware setup is active:
-```
- $ autorandr
- mobile
- docked (detected)
-```
-To automatically reload your setup, just append `--change` to the command line
+ $ autorandr
+ mobile
+ docked (detected)
+
+To automatically reload your setup:
+
+ $ autorandr --change
+
+To manually load a profile:
-To manually load a profile, you can use the `--load <profile>` option.
+ $ autorandr --load <profile>
+
+or simply:
+
+ $ autorandr <profile>
autorandr tries to avoid reloading an identical configuration. To force the
-(re)configuration, apply `--force`.
+(re)configuration:
+
+ $ autorandr --load <profile> --force
To prevent a profile from being loaded, place a script call _block_ in its
directory. The script is evaluated before the screen setup is inspected, and
If no suitable profile can be identified, the current configuration is kept.
To change this behaviour and switch to a fallback configuration, specify
-`--default <profile>`.
+`--default <profile>`. The system-wide installation of autorandr by default
+calls autorandr with a parameter `--default default`. There are three special,
+virtual configurations called `horizontal`, `vertical` and `common`. They
+automatically generate a configuration that incorporates all screens
+connected to the computer. You can symlink `default` to one of these
+names in your configuration directory to have autorandr use any of them
+as the default configuration without you having to change the system-wide
+configuration.
+
+## Hook scripts
+
+Three more scripts can be placed in the configuration directory (as
+(as defined by the [XDG spec](https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html),
+usually `~/.config/autorandr` or `~/.autorandr` if you have an old installation
+for user configuration and `/etc/xdg/autorandr` for system wide configuration):
+
+- `postswitch` is executed *after* a mode switch has taken place. This can be
+ used to notify window managers or other applications about the switch.
+- `preswitch` is executed *before* a mode switch takes place.
+- `postsave` is executed after a profile was stored or altered.
+- `predetect` is executed before autorandr attempts to run xrandr.
+
+These scripts must be executable and can be placed directly in the configuration
+directory, where they will always be executed, or in the profile subdirectories,
+where they will only be executed on changes regarding that specific profile.
+
+Instead (or in addition) to these scripts, you can also place as many executable
+files as you like in subdirectories called `script_name.d` (e.g. `postswitch.d`).
+
+If a script with the same name occurs multiple times, user configuration
+takes precedence over system configuration (as specified by the
+[XDG spec](https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html))
+and profile configuration over general configuration.
+
+As a concrete example, suppose you have the files
+
+- `/etc/xdg/autorandr/postswitch`
+- `~/.config/autorandr/postswitch`
+- `~/.config/autorandr/postswitch.d/notify-herbstluftwm`
+- `~/.config/autorandr/docked/postswitch`
+
+and switch from `mobile` to `docked`. Then
+`~/.config/autorandr/docked/postswitch` is executed, since the profile specific
+configuration takes precedence, and
+`~/.config/autorandr/postswitch.d/notify-herbstluftwm` is executed, since
+it has a unique name.
+
+If you switch back from `docked` to `mobile`, `~/.config/autorandr/postswitch`
+is executed instead of the `mobile` specific `postswitch`.
+
+In these scripts, some of autorandr's state is exposed as environment variables
+prefixed with `AUTORANDR_`. The most useful one is `$AUTORANDR_CURRENT_PROFILE`.
+
+If you experience issues with xrandr being executed too early after connecting
+a new monitor, then you can use a `predetect` script to delay the execution.
+Write e.g. `sleep 1` into that file to make autorandr wait a second before
+running `xrandr`.
