 docker run --rm -it -v /YourPackageSrc:/go/work \

 ### Go linker flags override
 
-You can override Go linker flags and other flags by specifying environment variable for a container using `-e` option.
+Go linker and compiler flags can be specified using container environment variables via `-e` option.

+To set files to be owned by your current user by default, start the container with your current **uid/gid**.
 
 Use `-u` flag to start container with different user/group id.

 docker exec --rm -it -u "$UID:$GID" ...

-**Attention:** we recommend to mount your host GOPATH and GOCACHE instead of
