 ## Installing
-Currently if you want to test it, you need to build it on your own. In the future I might consider
-publishing the binary to the Release Page.
+You can pick up the latest release in the [Release tab](https://github.com/hassanalinali/Lesma/releases) and start using it. Lesma is currently being tested and provides binaries only on Unix. Compatibility between operating systems and architectures is not hard to achieve, but simply not a priority.
+In the case that your platform is not oficially supported, you need to build it on your own.

-In order to build Lesma, you need to have [Python 3.7](https://www.python.org/) installed. Currently it's tested only on Linux. It makes use of clang to compile the resulting object file currently, so you need it installed, but only running a file doesn't require clang.

 ## Switch statement
 
-**Every case needs a break** if you don't want to continue the flow to the next case, only the last case doesn't need a break, this means that the default would still need one if it's not the last case of the switch statement.
+**No implicit fallthrough**, this means that in comparison with languages like C, the equivalent to a break statement is implicit in Lesma, therefore you need to specify the `fallthrough` keyword for the flow to go downstream to the other cases. Break statements are not allowed inside a switch statement.
