 ## WHAT CAN IT DO?
 
-It can sign and timestamp PE (EXE/SYS/DLL/etc), CAB and MSI files. It supports
-the equivalent of signtool.exe's "-j javasign.dll -jp low", i.e. add a
-valid signature for a CAB file containing Java files. It supports getting
-the timestamp through a proxy as well. It also supports signature verification,
-removal and extraction.

 ## BUILDING
 
 This build technique works on Linux and macOS, if you have the necessary tools installed:
 ```
-  ./autogen.sh
+  ./bootstrap
   ./configure
   make
   make install
 ```
 
-* On Linux, (tested on Debian/Ubuntu) you may need `sudo apt-get update && sudo apt-get install build-essential autoconf libtool libssl-dev python3-pkgconfig libcurl4-gnutls-dev`
-* On macOS with Homebrew, you probably need to do these things before autogen.sh and configure:
