-# sbotools [![Build Status](https://travis-ci.org/pink-mist/sbotools.svg)](https://travis-ci.org/pink-mist/sbotools)
+# sbotools
 
 **[sbotools](https://pink-mist.github.io/sbotools/)** provides a ports-like interface to [slackbuilds.org](http://www.slackbuilds.org/).
 
+Here is an unofficial maintenance fork for sbotools.  Development for the original has stopped for a number of years.
+
+## Auditing Changes
+
+You can audit the forked changes by asking git to show commits since the last known official commit.
+
+```
+git remote add pink-mist https://github.com/pink-mist/sbotools
+git fetch pink-mist
+git show pink-mist/master..
+```
+
+The latest changes on the master branch can be verified using the maintainer's
+[GPG Key](./GPG-KEY) included in the project.  The 'FINGERPRINT' should not
+change unless the maintainer does.
+
+```
+FINGERPRINT=D0CFFD1075CAB8DA329975078D147EEA19EFF029
+
+if ! gpg2 --list-keys | grep "$FINGERPRINT" >/dev/null; then
+  gpg2 --import ./GPG-KEY
+fi
+if git verify-commit origin/master; then
+  echo "verification ok"
+else
+  echo "verification failed"
+fi
+```
+
