 Provides NVidia GPU data to gotop
 
+## Compiling
+
+The easiest way is to not try to compile from this repository, but use the [gotop-builder](github.com/xxxserxxx/gotop-builder):
+
+```
+mkdir gotop-nvidia
+cd gotop-nvidia
+go run github.com/xxxserxxx/gotop-builder -r v4.1.0 github.com/xxxserxxx/gotop-nvidia
+go build -o gotop-nvidia ./gotop.go
+```
+
+Check the documentation for gotop-builder, and the source -- it's not a very long file.  What this program does is downloads the `gotop.go` command file, modifies it to import the nvidia code (this project), and creates an appropropriate `go.mod` to import the main gotop project. You end up with `gotop.go` and a `go.mod` files in the directory, which you can then build into an executable with the nvidia plugin.
+
+If you need or want to compile locally (such as, for development), there are a couple of variations. It ain't trivial.
+
+### If you want to use the gotop code from github directly
+
+From this repository, run:
+
+```
+mkdir tmp
+cd tmp
+go run github.com/xxxserxxx/gotop-builder -r v4.1.0 github.com/xxxserxxx/gotop-nvidia
+echo 'replace github.com/xxxserxxx/gotop-nvidia => ../' >> go.mod
+go build -o gotop .
+```
+
+This builds with the checked-out nvidia code.
+
+### If you want to use the gotop code from a local path
+
+then do everything in the previous example, but before compiling do an additional replacement:
+
+```
+echo 'replace github.com/xxxserxxx/gotop/v4 => ../../gotop' >> go.mod
+```
+
