 ##### Limitations
  * The extraction specifically looks for usages of a `translate` function with the correct signature. This may result in 
    false positives dependent on your code base.
+ * It is not currently possible to add notes/comments to a translation entry.
  * For the correct values to be parsed, the string arguments to the `translate` function **must** be inlined strings 
    (quoted or heredoc). It is **not** possible to use variables.
