-[Termux](https://termux.com/) is an Android app that can run some
-Linux software in a terminal.
-
-git-annex is not currently part of the Termux distribution, but it's easy
-to install it. Paste these commands into Termux:
-
-	pkg install wget
-	wget https://git-annex.branchable.com/install/Android/git-annex-install.sh
-	sh git-annex-install.sh
-
-Now you can set up a git-annex repository or two, to manage your
-Android files. To avoid typing any more, you can start up the
-git-annex webapp and set things up in there:
-
-	git annex webapp
-
-Or you can continue using git-annex at the command line. Here we'll make a
-repository for photos:
-
-	cd ~/storage/dcim
-	git init
-	git annex init
-
-You can go on to set up a ssh remote pointing to a server, and sync
-your files to and from it. 
-
-And so on. Most ways you would use git-annex on a Linux system work fairly
-well in this Termux environment.
-
-## Starting on boot
-
-If you install the Termux:Boot app, git-annex will also integrate with it.
-Repositories you create with the webapp (or listed in
-~/.config/git-annex/autostart) will have the assistant started in them on
-boot, so you don't need to start it manually.
-
-## Known limitations
-
-* Direct mode
-
-  git-annex will probably default to direct mode due to the
-  limitations of Android's /sdcard. You can get around this using v6
-  unlocked repositories, or by putting the git-annex repository on a better
-  filesystem on the Android device, such as your termux home directory.
-
-## Upgrading
-
-To upgrade to a new git-annex release, just run
-`git-annex-install.sh` again.
