 # docset-server
 
-docset-server
+This is a simple "Docset Viewer".  It is intended to browse documentation
+offline, in a web browser.
+
+Docsets are sqlite3 files containing a search index and a directory structure
+of HTML files. They are typically used for reading technical documentation offline.
+
+You can read more about them here:  https://kapeli.com/docsets
+
+# Your ~/.docset directory
+
+By default, docsets go in your ~/.docset directory. 
+
+One or more "docset directories" can exist in your ~/.docset 
+directory. (A docset is a directory of files) 
+
+If you have the Zeal program installed, the command
+below will allow you to use the same docset files:
+
+  ln -s .local/share/Zeal/Zeal/docsets .docset
+
+# Viewing Docset Files
+
+The program docset_server.js can be used to start an HTTP server which 
+serves up your docset files to a web browser.
+
+Navigate to http://localhost:8080/ to search your docset files.
+
+The "Options" menu allows you to specify which docset(s) you'd like to search,
+as well as the type of information to search for. These are simple check boxes,
+and you can use regular expressions to "mass-select" one or more options from
+the list.
