+# PDFSignatureRemover [![](https://img.shields.io/jenkins/s/https/ci.dmoj.ca/job/PDFSignatureRemover.svg)](https://ci.dmoj.ca/job/PDFSignatureRemover/)
+
+Sometimes, you have to open signed PDF files. Digital signature is good
+and everything, but it leaves an annoying warning if the signature fails
+to verify. If you are using Adobe Reader, every time you open the file, it
+complains that the signature is invalid.
+
+`PDFSignatureRemover` is a tool that can remove the pesky signatures for you.
+
+## Usage
+
+```
+$ wget https://ci.dmoj.ca/job/PDFSignatureRemover/lastSuccessfulBuild/artifact/target/PDFSignatureRemover-1.0-SNAPSHOT.jar -O PDFSignatureRemover.jar
+$ java -jar PDFSignatureRemover.jar signed.pdf output.pdf
+```
+
+This will convert `signed.pdf`, with a PDF signature, to `output.pdf`,
+without the signature.
