Uykfd requires the following environment variables to be defined before it is used:

1. UYKFD_DB_URL - Usually this is "jdbc:mysql://127.0.0.1". The database name is hardwired as "uykfd".
2. UYKFD_DB_USER - The database user. For a basic MySQL installation this is probably "root"
3. UYKFD_DB_PASSWORD - The password for the database user. For a basic MySQL installation this might be the empty string, "".
4. UYKFD_LASTFM_APIKEY - The value of an API Key from Last FM.

Once this is done, you can run Uykfd as follows:

  java -jar uykfd-all-X.Y.jar

(where X.Y is the appropriate version number). You might want to define an alias or batch file to simplify this.

Next: build a database of files.
