+The branch named "main" is the upstream main branch where development occurs.
+
+The branch name `2026.1` is the stable release this year, which means that new features from the main branch go here when they are considered sufficiently mature and stable.
+
+The tag  `2026.1(TeXLive)` corresponds to the synctexdir directory of TeXLive svn repository from the 2026 release.
+
+All other branches are secondary.
+
+See synctex_version.h to see the latest version of synctex and of the parser.

+# SyncTeX
+
+Synchronization for TeX
+
+The tagged history points are a partial clone of synctexdir in the TeXLive svn repository, see the online [TeXLive repository](http://www.tug.org/svn/texlive/trunk/Build/source/texk/web2c/synctexdir/).
+
+The focus here is on the client side code for synchronization between text editor and pdf viewer. The files are not always forwarded to TeXLive as is.
+
+Instructions for building and testing are available in [./meson/README.md](https://github.com/jlaurens/synctex/blob/main/meson/README.md).
