How do I actually get started using this tool?

I followed the instructions in the README.md, they were easy. However, it is not obvious what to do once the command will execute on the command line...

Here's my attempt to load the existing SDSS query log into the database: qwla sdss consume workloadanalysis/ProcessedQueries_sdss.csv -v -d sqlite:///sdss.db

Output: Imported 1 of 1 (workloadanalysis/ProcessedQueries_sdss.csv)

However, it does not seem to have done anything to the DB:

% sqlite3 sdss.db 
SQLite version 3.7.13 2012-07-17 17:46:21
Enter ".help" for instructions
Enter SQL statements terminated with a ";"
sqlite> .schema
CREATE TABLE everything (
    id INTEGER NOT NULL, 
    PRIMARY KEY (id)
);
sqlite> select * from everything;
sqlite>

query-workload-analysis % ls -l *.db
-rw-r--r-- 1 dhalperi staff 2048 Jul 30 17:06 sdss.db

So, it seems like it did not actually put any data in the database. What am I doing wrong?

FYI: @domoritz @shrjain @7andrew7

Start with README.md and the reported qwla ... consume ... -d sqlite:///sdss.db command, then inspect the generated sdss.db with sqlite3. Clarify the expected post-import workflow and database contents, and update the usage documentation so a newcomer can verify a successful import.
