A comment is a line that is stripped when Aneamal is translated into a webpage or a different output format. Authors use comments for annotations that readers shall not see or to hide content temporarily until it is relevant.
Start a line with a percent sign to turn it into a comment like in the example below.
Roses are red, Violets are blue, %Parakeets are indiscreet, %Vipers are venomenous, %Sharks are cartilaginous, %Dairy cows say "moo", Sugar is sweet, And so are you.
Roses are red,
Violets are blue,
Sugar is sweet,
And so are you.
If you want to comment many lines out, prepending each line with a percent sign may seem impractical, especially when the lines shall only be hidden temporarily. Consider using sandwich markup then. The following example is equivalent to the one above:
Roses are red, Violets are blue, /%/. Parakeets are indiscreet, Vipers are venomenous, Sharks are cartilaginous, Dairy cows say "moo", . Sugar is sweet, And so are you.
