A composition comprising a complete^[a] catalogue of our civil code, a canticle in C:

Be courageous.

Be congenial, never churlish

Be choosy in your compositions.

Be careful with copyright.

Cite well and cite often.

Call yourself something classy

Consider collaborators charitably; critique content, never character.

Chew the fat and not the children.

For cuisine, choose cream sans cherries, sans chickpeas.

Compromise and do not clash.

Censor not lest ye be censored.

While cycling, be circumspect and curb your contradictions

Cherish contributions but do not covet them.

Be clear but not clairvoyant.

Be constructive but not creative.

Do not con.

Be competent.

Be cautious when close to controversy or celebrity.

Call for counsel, not the courts.

A counterfeit caught is quickly catapulted.

Never a chronicle nor a compendium compose,

Nor combine claims to concoct conclusions.

Canvas is for canopies.

Coins cause conflicts.

Leave closets closed.

The cure for compulsion is cessation or confinement.

Chuck out the cudgel, conclude your clobbering,

Cut the crap,

... and comprehensively countermand commandments!
