As follows / as above (如下/如上)

Structure … + 如下：+ list／如上 + noun（所述）

如下 (rúxià, "as follows") and 如上 (rúshàng, "as above") are deictic document connectors: they point the reader downward, to a list or detail about to come, or upward, to what has already been laid out. 如下 closes an opening sentence and is usually followed by a colon: 具体安排如下：… 如上 closes or sums up: 如上所述 = "as stated above". They mark written, formal register (reports, contracts, instructions); in speech one would just say 像下面这样 or 上面说的.
