Backend is implemented as a serverless action with api gateway route
+## Installing
+
+### Deploy action
+Configure the `wsk` CLI with authentication and host
+
+Create the action using `wsk` CLI and set default parameters
+```
+wsk create slackinvite action.js -p org "myslackteam" -p slacktoken "xop-12345..."
+```
+
+The org is the Slack team name, usually the hostname from your .slack.com.
+The slacktoken is a token for a user with admin access. You can get one from https://api.slack.com/docs/oauth-test-tokens
+Recommend creating a bot user with admin to use for invites.
+
+Verify the action by invoking with the `wsk` CLI
+```
+wsk action invoke slackinvite -p email "user@example.com"
+```
+
+The action should do a http call to the slack API using the team host and token, then Slack will send the invite to the email provided.
+
+### Expose action
+Create a public url to invoke the action using `wsk` CLI
+```
+wsk api-experimental create /openwhisk-team /slackinvite GET slackinvite
+```
+The command will print the new url created
+```
+ok: created api /slackinvite GET for action slackinvite
+https://21ef035.api-gw.mybluemix.net/openwhisk-team/slackinvite
+```
+
+Verify the exposed url by invoking using the `curl` CLI or a web browser
+```
+curl -X GET https://21ef035.api-gw.mybluemix.net/openwhisk-team/slackinvite?email=user@example.com
+```
+
+## Update index.html
+Edit the line `var actionUrl = "https://...";` and replace the value with your new url that expose your new action.
+
+## Deploy to github-pages
+Create a new github repo, then go to settings, and set master branch as github page.
+Push the modified `index.html` to the new repo, then your webpage would be accesible from https://$username.github.io/$reponame
