+# API Reference
+
+## How to register
+* First you need to create a pull request with your `domains/my-domain.json` file
+* This PR will be reviewed, merged
+* The changes will take effect in less than a day after the PR gets merged
+* `Github pages` users, need to go to their repo settings page and change the domain to `your-domain.is-a.dev` after everything is done
+* And that's it
+
+Example (for github pages) -
+```json
+{
+  "description": "Add some description",
+  "repo": "https://github.com/user/user.github.io",
+  "owner": {
+    "username": "your-github-username",
+    "email": "any@email"
+  },
+  "records": {
+    "CNAME": "user.github.io"
+  }
+}
+```
+
+
+## Domains json file
+The way you register your own domain name is through a pull request.
+To register `my-domain.is-a.dev`, you need to create a `domains/my-domain.json` file
+
+### owner (required)
+You need to specify some information about yourself here.
+This is so that you can be contacted if required.
+
+In the owner object, the fields `username` and `email` are required. You can however add more information in this object if you need.
+```json
+{
+  "owner": {
+    "username": "github-username",
+    "email": "any@email"
+  },
+}
+```
+
+### description
+Describe your domain name and your usage. This is purely for documentation purpose and is optional.
+
+
+### repo
+This is a link to your website repository or your github account. This is purely for documentation purpose and is optional.
+
+
+### records
+This is where you specify how you want to link to your server/webpage.
+
+Currently, only `CNAME`, `ALIAS`, `A`, `URL` record types are supported.
+
+##### CNAME/ALIAS
+Replace CNAME with ALIAS for alias record type
+```json
+{
+  "records": {
+    "CNAME": "username.github.io"
+  }
+}
+```
+
+##### A record
+```json
+{
+  "records": {
+    "A": [
+      "999.999.991.999",
+      "999.999.992.999",
+      "999.999.993.999",
+      "999.999.994.999",
+    ]
+  }
+}
+```
+
+##### URL redirection
+```json
+{
+  "records": {
+    "URL": "https://my-other-website.com"
+  }
+}
+```
+
+##### Force HTTPS on your CNAME (or ALIAS or A) record
+```json
+{
+  "records": {
+    "CNAME": "username.github.io",
+    "URL": "https://your-domain.is-a.dev"
+  }
+}
+```
