+  releases from GitHub but later we'll add support for brew, rpm, deb and more.
+
+  - detect is currently unimplemented but would use your OS's package manager

+  - standalone installs a standalone release archive into ~/.local

+
+--prefix ~/.local
+  Controls the unix hierarchy path into which standalone releases are installed.
+  Defaults to ~/.local. You may also want to use /usr/local
+  Remember that whatever you use, you must have the bin directory of your prefix
+  path in \$PATH to execute the d2 binary. For example, if my prefix directory is
+  /usr/local then my \$PATH must contain /usr/local/bin.
+
+--tala

+  uninstall first before installing the new version. The install assets will not be deleted
+  from ~/.cache/d2/install.
+
+--uninstall:
+  Uninstall the installed version of d2. The --method flag must be the same as for
+  installation. i.e if you used --method standalone you must again use --method standalone
+  for uninstallation. With detect, the install script will try to use the OS package manager
+  to uninstall instead.
+
+All downloaded assets are cached into ~/.cache/d2/install. use \$XDG_CACHE_HOME to change

+
+You can rerun install.sh to update your version of D2. install.sh will avoid reinstalling
+if the installed version is the latest unless --force is passed.
