-# Known issues
-
-## Rails integration
-
-This gem implements support of `*.babl` views in [Rails](https://github.com/rails/rails/).
-
-Ideally, the template should be compiled once for all and re-used for all subsequent requests. In practice, today's implementation will re-compile the template at every request, because Rails templating mechanism doesn't make our life easy. Template compilation time is non negligible, and it could become a real problem with [code generation](https://github.com/getbannerman/babl/pull/21).
-
-I will probably hack something soon in order to work around this issue.
