-#  Adapted from https://github.com/caddyserver/getcaddy.com
+#          FILE: default.txt
+# 
+#         USAGE: curl https://getcroc.schollz.com | bash

 #
-#                  croc Installer Script
+#                This script installs croc into a specified prefix.
+#                Default prefix = /usr/local/bin
 #
-#   Homepage: https://schollz.com/software/croc
-#   Issues:   https://github.com/schollz/croc/issues
-#   Requires: bash, mv, rm, tr, type, curl/wget, base64, sudo (if not root)
-#             tar (or unzip on OSX and Windows)
+#       OPTIONS: -p, --prefix "${INSTALL_PREFIX}"
+#                      Prefix to install croc into.  Defaults to /usr/local/bin
+#  REQUIREMENTS: bash, uname, tar/unzip, curl/wget, sudo (if not run
+#                as root), install, mktemp, sha256sum/shasum/sha256
 #
-# This script safely installs Caddy into your PATH (which may require
-# password authorization). Use it like this:
+#          BUGS: ...hopefully not.  Please report.
 #
-#	$ curl https://getcroc.schollz.com | bash
-#	 or
-#	$ wget -qO- https://getcroc.schollz.com | bash
-#
-# In automated environments, you may want to run as root.
-# If using curl, we recommend using the -fsSL flags.
-#
-# This should work on Mac, Linux, and BSD systems, and
-# hopefully Windows with Cygwin. Please open an issue if
-# you notice any bugs.
