or:

{{Addition|line|pool|statement|depend|1 or 2|comment}}

where:

line is the number of the line on the tableau proof where the Rule of Addition is to be invoked
pool is the pool of assumptions (comma-separated list)
statement is the statement of logic that is to be displayed in the Formula column, without the $ ... $ delimiters
depend is the line of the tableau proof upon which this line directly depends
1 or 2 should hold 1 for Addition_1, and 2 for Addition_2
comment is the (optional) comment that is to be displayed in the Notes column.
