+# The `luamathalign` package for LuaLaTeX
+
+With `amsmath`'s `align` environment simple equations can be aligned easily, e.g.
+
+```tex
+2  &=1+1\\
+2-1&=1
+```
+
+but even just adding an underline makes this much more complicated. E.g.
+
+```tex
+2  &=1+1\\
+\underline{2-1&=1}
+```
+
+is not allowed. Similarly alignment points surrounded by `\left` and `\right`
+or points nested in other environments do not work.
+
+For LuaLaTeX this can be solved with luamathalign. It adds a command `\AlignHere`
+which behaves mustly like `&` except that it's allowed almost anywhere. E.g.
+
+```
+                      2 &= 1+1\\
+\underline{2-1 \AlignHere= 1}
+```
+
+
+Licensed under the LPPL v1.3c or later.
