-'''LHA''' is an archiving program and file format created by Haruyasu Yoshizaki (a.k.a. Yoshi) in 1988. It was originally called '''LHarc''', then was briefly '''LH''' (v2.02–2.04), then '''LHa''' (v2.05–2.06), before settling on '''LHA''' (v2.10+). In the 1990s, it was the most popular archiving format on the Amiga platform. It also got some use on the PC platform including in the installers for id Software games such as Doom and Quake, because [[ZIP]] compression was inferior until the release of PKZIP 2.0, which brought the formats to parity.
+'''LHA''' is a family of archiving programs, and their associated file format, created by Haruyasu Yoshizaki (a.k.a. Yoshi). The software was originally called '''LHarc''', then was briefly '''LH''' (v2.02–2.04), then '''LHa''' (v2.05–2.06), before settling on '''LHA''' (v2.10+). The file format is also known as '''LZH'''. See the [[LZH|LZH disambiguation page]] for other "LZH" formats.
 It was particularly popular in Japan. Most of the best information about it is in Japanese.

 It supports a number of different compression schemes, most of which use [[LZ77 with Huffman coding|LZ77 combined with Huffman coding]].
-The file format is also known as '''LZH'''. See the [[LZH|LZH disambiguation page]] for other "LZH" formats.
+This article covers the format used by LHarc/LHA, as well as "generalized" LHA format: the same file format, but with other compression schemes. The generalized format was possibly designed by Kazuhiko Miki for [[LArc]], but confirmation of this is needed. If so, it was soon borrowed by LHarc, with new compression schemes.
