-# local-cert-generator
+# HTTPS for `localhost`
+
 A set of scripts to quickly generate a HTTPS certificate for your local development environment.
+
+## How-to
+
+1. Clone this repository and `cd` into it:
+
+```
+git clone https://github.com/dakshshah96/local-cert-generator.git
+cd local-cert-generator
+```
+2. Run the script to create a root certificate:
+
+```
+sh createRootCA.sh
+```
+
+3. Trust this certificate after importing it to your System keychain:

+
+4. Run the script to create a domain certificate for `localhost`: 
+
+```
+sh createSelfSigned.sh
+```
+
+5. Move `server.key` and `server.crt` to an accessible location on your server and include them when starting it. In an Express app running on Node.js, you'd do something like this:
+
+```js
+var path = require('path')
+var fs = require('fs')
+var express = require('express')
+var https = require('https')
+
+var certOptions = {
+  key: fs.readFileSync(path.resolve('build/cert/server.key')),
+  cert: fs.readFileSync(path.resolve('build/cert/server.crt'))
+}
+
+var app = express()
+
+var server = https.createServer(certOptions, app).listen(443)
+```
