+# For github pages
+
+### Creating a github pages repo
+You can create a github pages website by creating a repo with the name `<your-github-username>.github.io`.
+For more information about github pages, please read through [their guide](https://guides.github.com/features/pages/).
+
+
+### Domains file
+Create a json file inside the `domains` directory (`domains/<subdomain>.json`) with the following contents
+```json
+{
+  "description": "Add some description",
+  "repo": "https://github.com/github-username/github-username.github.io",
+  "owner": {
+    "username": "github-username",
+    "email": "any@email",
+    "twitter": "your-twitter-username"
+  },
+  "record": {
+    "CNAME": "github-username.github.io"
+  }
+}
+```
+
+### Configuring your repo
+* After the pull request is merged, you will see a 404 error on `your-domain.is-a.dev`. To fix this go to your github page repo's `Settings > Github pages > Custom domain` and add `your-domain.is-a.dev` in the given field
+* Check the `Enforce HTTPS` checkbox below the custom domain input
