+# Build Support Stack
+
+## Instructions
+
+JS/TS/NPM builds need an npm registry to store intermediate package artifacts.
+This can be supplied by the user (e.g. using a hosted registry or even npmjs.com), or a local registry using gitea can be deployed by stack orchestrator.
+To use a user-supplied registry set these environment variables:
+
+`CERC_NPM_REGISTRY_URL` and 
+`CERC_NPM_AUTH_TOKEN`
+
+Leave `CERC_NPM_REGISTRY_URL` un-set to use the local gitea registry.
+
+### Build support containers
+```
+$ laconic-so --stack build-support build-containers
+```
+### Deploy Gitea Package Registry
+
+```
+$ laconic-so --stack package-registry setup-repositories
+$ laconic-so --stack package-registry deploy-system up
+This is your gitea access token: 84fe66a73698bf11edbdccd0a338236b7d1d5c45. Keep it safe and secure, it can not be fetched again from gitea.
+$ export CERC_NPM_AUTH_TOKEN=84fe66a73698bf11edbdccd0a338236b7d1d5c45
+```
+Now npm packages can be built:
+### Build npm Packages
+```
+$ laconic-so build-npms --include laconic-sdk
+```
