 While this repository can be used as a library of sorts to call the HCS apis, there are a couple binaries built out of the repository as well.

+
+### Linting
+
+Code must pass a linting stage, which uses [`golangci-lint`][lint].
+Since `./test` is a separate Go module, the linter is run from both the root and the
+`test` directories. Additionally, the linter is run with `GOOS` set to both `windows` and
+`linux`.
+
+The linting settings are stored in [`.golangci.yaml`](./.golangci.yaml), and can be run
+automatically with VSCode by adding the following to your workspace or folder settings:
+
+```json
+    "go.lintTool": "golangci-lint",
+    "go.lintOnSave": "package",
+```
+
+Additional editor [integrations options are also available][lint-ide].
+
+Alternatively, `golangci-lint` can be [installed][lint-install] and run locally:
+
+```shell
+# use . or specify a path to only lint a package
+# to show all lint errors, use flags "--max-issues-per-linter=0 --max-same-issues=0"
+> golangci-lint run
+```
+
+To run across the entire repo for both `GOOS=windows` and `linux`:
+
+```powershell
+> foreach ( $goos in ('windows', 'linux') ) {
+    foreach ( $repo in ('.', 'test') ) {
+        pwsh -Command "cd $repo && go env -w GOOS=$goos && golangci-lint.exe run --verbose"
+    }
+}
+```
+
+### Go Generate
+
+The pipeline checks that auto-generated code, via `go generate`, are up to date.
+Similar to the [linting stage](#linting), `go generate` is run in both the root and test Go modules.
+
+This can be done via:
+
+```shell
+> go generate ./...
+> cd test && go generate ./...
+```
