 ## Introduction
 RP2 supports most countries each of which has different accounting methods and report generators, as explained in the sections below. Some countries have direct support (by means of a country-specific RP2 plugin), but other countries can still benefit from RP2 via the generic country plugin (see below).
 
+## Accounting Methods
+RP2 supports the following accounting methods (although not all countries support all accounting methods):
+  * [FIFO](https://www.investopedia.com/terms/f/fifo.asp);
+  * [LIFO](https://www.investopedia.com/terms/l/lifo.asp);
+  * [HIFO](https://www.investopedia.com/terms/h/hifo.asp);
+  * LOFO: lowest cost in, first out. This is the opposite of HIFO.
