 ## Building nexus-exam
 
-For now, the only supported combination of OS and architecture for nexus-exam is Linux/amd64. Please note that it cannot be built statically as some static libraries are missing.
+For now, the only supported combination of OS and architecture for nexus-exam is Linux/amd64.
 
 Similarly to nexush and nexus-cli, nexus-exam requires `SERVER` and `CERT` environment variables (see [Building nexush and nexus-cli](#building-nexush-and-nexus-cli)). Furthermore, two other environment variables are required: `EXAM_USER` and `EXAM_PWD`. These define the credentials for the user used by nexus-exam to connect to the nexus server. On the server side, make sure this user has the `VM_ATTACH_ANY` capability.
