 # Getting started
 You need to compile the compiler or use a precompiled version of it.
 The samples folder offers examples on the usage for the different supported languages. These folders show some sample asn1 files, the command line and the expected output of the compiler.
+See [samples/readme.md](samples/readme.md) for the current TypeScript microservice sample layout and required Node/pnpm setup.
 
 # Building the compiler
 ## Prerequesites to compile the compiler
 * Have cmake installed 
   * https://cmake.org
-  * at least V3.21
+  * at least V3.20
   * available in the path
