🐇

"In the land of code, where the shadows lie,

Changes come, under the cloudless sky.

Docker's ship sails, with a new command,

And environment secrets, are safely in hand.

The README tells tales, of builds and of tests,

While the image version, simply adjusts to its best.

So here's to the code, ever-changing, ever-new,

To the next update, we say, 'adieu'!" 🥕🎉
