+Brainfuck is sort of the poster child for [[esolangs]].
+
+Brainfuck operates on an array of memory cells, each initially set to zero. There is a pointer, initially pointing to the first memory cell. You then increment and decrement along the memory cells, and are able to preform limited actions on cells.
+
+* move the pointer right, >
+* move the pointer left, <
+* increment the memory cell at pointer, +
+* decrement the memory cell at pointer, -
+* output character signified by the memory cell at pointer, .
+* input character and store it in the memory cell at pointer, ,
+* jump past the matching ] if the cell at the pointer is 0, [
+* jump back to the matching [ if the cell at the pointer is nonzero, ]
+
+
+All characters other than ><+-.,[] are typically considered comments and ignored.
