-#+title: gra
-#+subtitle: Add new Git remotes quickly
-
-
-/gra/ (short for =git remote add=) is a small Bash script which allows to add new Git remotes easily.
-New remote URLs will be added with the same URL scheme as the one of the =origin= remote.
-The only argument which is needed is a =REMOTE_NAME=,
-
-#+begin_example
-  $ gra Deleh
-  Adding remote origin-Deleh with URL git@github.com:Deleh/example.git
-  Fetching from remote origin-Deleh
-  From github.com:Deleh/example
-   * [new branch]      main       -> origin-Deleh/main
-#+end_example
-
-* Usage
-
-#+begin_example
-  Usage: gra [OPTIONS] REMOTE_NAME
-
-  Add a Git remote by providing a single name.  All remotes get listed if no
-  REMOTE_NAME is provided.
-
-  REMOTE_NAME  Name of the remote
-
-  OPTIONS
-    -h, --help  Show this help message and exit
-#+end_example
-
-** Shorthands
-
-Shorthands can be defined in =~/.config/gra.config= for example like this:
-
-#+begin_src sh
-  ex=example
-  slu=SuperLongUsername
-#+end_src
-
-They can be passed as =REMOTE_NAME= argument, which is handy for often-used, long remote names.
-Autocompletion is available for all defined shorthands.
-
-* Installation
-
-** Manual
-
-Place the =gra= script in your =$PATH=.
-To use the autocompletion feature source the =gra_completion.bash= script.
-
-** Script
-
-An installation script for Bash (=install.bash=) is provided which will link the two files to =~/.local/{bin/gra,share/bash-completion/completions/gra}= and add the corresponding entries to =~/.bashrc=.
-Further updates of /gra/ require just =git pull=.
-
-** Nix Flake
-
-This repository is also a [[https://nixos.wiki/wiki/Flakes][Nix Flake]].
-/gra/ is provided as package under =github:Deleh/gra#gra=.
