-All of this is included in the `tcc` directory.
+First you need to set up TCC.
 
 1. Install TCC.
 2. Download https://sourceforge.net/projects/mingw/files/MinGW/Base/w32api/w32api-3.14/
-3. Copy the ``include`` directory of this into `tcc/include/winapi`.
-4. Run `compile.bat`.
+3. Copy the ``include` directory of this into ``tcc/include/winapi``.
+
+After that, run ``compile.bat``. ``wlb.exe`` should be ready to run.
+
+-----
+Usage
+-----
+
+``wlb.exe`` executes each argument to it in sequence. Most of the time
+you will run ::
+    wlb.exe \V \D dbname.wlb \A dir1 \A dir2 ...
+
+``\V`` turns on verbose mode, which reports the name of each file
+as it is being read. You can remove this to make WLB only report errors, or
+you can use ``\VV`` to turn on debug mode.
+
+``\D`` denotes the name of the database. This must come before all archive
+commands. There can only be one ``\D`` specified per run. If specified file
+does not exist, it will be created. If the file is a SQL database whose user
+version is not a supported WLB version, the program will report an error and
+close.
+
+``\A`` requests WLB to archive a file or directory. If what follows is a
+directory, then WLB will archive every file under the directory, and in the
+directories under that, etc. There can be multiple ``\A`` commands corresponding
+to different files/directories.
