+# Installing in Production
+
+Be familiar with the steps in [Installation][] below, since it is needed to
+build the Angular app first.
+
+Once the Angular app is built, provision a small base-64-lts 20.4.0 VM,
+connected solely to the external network (aka public Internet). From within
+the VM, the following steps are needed:
+
+    pkgin in gmake
+    mkdir -p /opt/spearhead/portal
+
+From this repo, copy in bin/, cfg/, smf/, static/ (since this is a symlink,
+this means the build in app/dist should be copied into static/ in prod), and \*.
+Notably, avoid app/ and node\_modules. In production, adjust the config in
+/opt/spearhead/portal/cfg/prod.json. Lastly:
+
+    pushd /opt/spearhead/portal
+    npm install
+    svccfg import smf/service.xml
+    svcadm enable portal
+    popd
+
+The application will now be running.
+
 # Installation
 
+First install the server-side libraries:
+
     npm install
 
-# Generate server certificates
+Then install the Angular compiler needed for the client-side app:
 
-From within the config/ directory:
+    npm install -g @angular/cli
+    pushd app && npm install && popd
 
+## Build the client-side app:
+
+    pushd app && npm run build && popd
+
+## Generate server certificates
+
+    pushd config
     openssl genrsa -out key.pem
     openssl req -new -key key.pem -out csr.pem
     openssl x509 -req -days 9999 -in csr.pem -signkey key.pem -out cert.pem
     rm csr.pem
+    popd
 
-# Configuration
+## Configuration
 
-Ensure the config file in config/ matches your details.
+Ensure the config file in config/ matches your details. If running in
+production, name the config file config/prod.json.
+
+Relevant configuration attributes:
+
+- server.port: the port this server will serve the app from
+- server.key: path to the private key for TLS
+- server.cert: path to the PKIX certificate for TLS
+- urls.local: the domain or IP the SSO will redirect back to (aka this server)
+- urls.sso: the URL to the SSO
+- urls.cloudapi: the URL to cloudapi
+- key.user: name of Triton user who has "Registered Developer" permission set
+- key.id: SSH fingerprint of Triton user (same as what node-triton uses)
+- key.path: path to private key of Triton user
 
 The SSH key used must be the correct format, e.g. generated with:
 
     ssh-keygen -m PEM -t rsa -C "your@email.address"
 
-# Running the server
+## Running the server
 
     node bin/server.js config/prod.json
 
+The server generates a lot of JSON data about every request. This is easier
+for a human to handle if they have bunyan installed ("npm install -g bunyan"),
+and instead:
+
+    node bin/server.js config/prod.json | bunyan
+
 # Endpoints
 
-## GET /static/*
+## GET /\*
 
 This is where all the front-end code goes. All files will be served as-is as
-found in that directory. The default is static/index.html. There is no
-authentication; all files are public.
+found in that directory (by default a symlink from static/ to app/dist). The
+default is static/index.html. There is no authentication; all files are public.
 
-## GET /login
+## GET /api/login
 
 Call this endpoint to begin the login cycle. It will redirect you to the SSO
 login page: an HTTP 302, with a Location header.
 
-## GET /token
+## GET/POST/PUT/DELETE/HEAD /api/\*
 
-Upon successful login, the SSO login page will redirect to this endpoint. This
-endpoint will return a 204, along with a X-Auth-Token header that must be saved
-by the front-end code. All subsequent calls should provide this X-Auth-Token
-header.
-
-## Other
-
-All other calls will be passed through to cloudapi. For these calls to succeed,
-they MUST provide the X-Auth-Token header that the /token endpoint returns.
+All calls will be passed through to cloudapi. For these calls to succeed,

 # Interaction cycle
 
-client --- GET /login --------> this server
-       <-- 302 Location #1 ----
+    client --- GET /api/login --------> this server
+           <-- 302 Location #1 ----
 
-client --- GET <Location #1> --> SSO server
-       <separate SSO cycle>
-       <-- 302 Location #2 ----
-
-client --- GET <Location #2> --> this server
-       <-- 204 X-Auth-Token ----
+    client --- GET <Location #1> --> SSO server
+           <separate SSO cycle>
+           <-- 302 with token query arg
 
 From now on call this server as if it were a cloudapi server (using [cloudapi
 paths](https://github.com/joyent/sdc-cloudapi/blob/master/docs/index.md#api-introduction)),
-always providing the X-Auth-Token. For example, to retrieve a list of packages:
+except prefixing any path with "/api". Also always provide the X-Auth-Token.
 
-client --- GET /my/packages --> this server
-       <-- 200 JSON body ------
+For example, to retrieve a list of packages:
+
+    client --- GET /api/my/packages --> this server
+           <-- 200 JSON body ------
 
 The most useful cloudapi endpoints to begin with will be ListPackages,
 GetPackage, ListImages, GetImage, ListMachines, GetMachine, CreateMachine and
