+6502 assembly code is full of LDA, STA, LDA, STA sequences.
 With xasm you can use MVA as a shortcut for an LDA/STA pair or even MWA for 16-bit transfers.
-You can avoid defining labels when you need short jumps,
-thanks to conditional skip and repeat pseudo-instructions.
-You can put two instructions that share their argument in one line.
+Short branches can be replaced with conditional skip and repeat pseudo-instructions.
+You can use a pair of instructions with a shared argument.
 These are just some of the features that help you program in a more concise way.
 Let's look at typical 6502 code (which is also valid in xasm):

+xasm syntax is an extension of Quick Assembler's (created in 1991 for Atari 8-bit).
+Accumulator shifts should be written as in `asl @`.
 Whitespace is important: it is required before the instruction
 and disallowed in the operands, because it separates a comment from the operand, e.g.
