# What is a “Spark?” A **Spark** is a potentially fleeting thought of variable length and complexity that is recorded as close to its birth as possible, often hastily, so as not to lose it, with the intention of further expanding upon it, or fleshing it out, at a later time. **Spark’s** are created with the goal of turning them, either on their own or by combining them with other Spark’s, into complete atomic notes.
