 # Mogan Editor / [墨干编辑器](README_ZH.md)
-Mogan Editor is a structured editor based on GNU TeXmacs.
+Mogan Editor is a structure editor delivered by the Xmacs Labs.
 
-Mogan is named after Mount Mogan[^1], a famous attraction in my hometown. 墨干(Mogan) literally means "dried ink". The word is derived from 莫干(Mogan) which is a combination of 莫(Mo) and 干(Gan)[^2].
+Mogan Editor is forked from GNU TeXmacs and a libre software.
 
-GNU TeXmacs is for Scientists, Mogan is for human beings.
+We customize GNU TeXmacs for everyone to enjoy it fluently.
 
-## Plans
-Mogan v1.0 (based on GNU TeXmacs 2.1.1) will be a baseline release with the following three major changes:
-+ Switch from GNU Guile 1.8 to S7
-+ Switch from Qt 4.x to Qt 5.x
-+ Change some of the default settings
+We develop new features for everyone to learn and create science and technology.
 
-Mogan v1.x will always be compatible with GNU TeXmacs 2.1.1.
+Mogan is named after Mount Mogan[^1], a famous attraction in my hometown. 墨干(Mogan) literally means "dried ink". The word is derived from 莫干(Mogan) which is a combination of 莫(Mo) and 干(Gan)[^2].

+
+  The most significant change of Mogan Editor v1.0.2 is that we've separated
+  the <menu|Help|Mogan> doc and migrated it to two remote <TeXmacs>
+  documents. And the release manager of Mogan Editor v1.0.2 is too lazy to
+  prepare the ChangeLog for Mogan Editor v1.0.2.
+
+  Here are the two remote <TeXmacs> documents.
