 ### Guidelines for imports
 
 It may be confusing to see different imports, so let's go over the most common examples:
 
-`@webapp` -> Refers to `pyroscope-oss`, aka `grafana/pyroscope` repo.
-`@pyroscope/webapp` -> Refers to `pyroscope-oss`, aka `grafana/pyroscope` repo.
+`@webapp` -> Refers to `pyroscope-oss`, aka [grafana/pyroscope] repo.
+`@pyroscope/webapp` -> Refers to `pyroscope-oss`, aka [grafana/pyroscope] repo.
 `@phlare` -> Refers to code in this repository. Note that this is needed since other
 downstream repositories may use this repository, and they also may want to override specific files.
 
-In the future, once both `grafana/pyroscope` and `grafana/phlare` are merged, there will
-be no need for `@webapp` and similar to happen, since there will be no `grafana/pyroscope` repo anymore.
+In the future, once both [grafana/pyroscope] and [grafana/phlare] are merged, there will
