 The code for [Bitraf.no](http://bitraf.no) website.
 
+## Structure
+
+Most of the Bitraf website is actually wiki-pages.
+
+The frontpage/landing-page is however stored here.
+
 ## Making changes
 
-`TODO: Document`
+You can use the Github webinterface to make changes. This is recommended for simple cases, like fixing a typo or improving the text.
+
+First, [log into or sign up](github.com/login) to Github.
+
+When logged in you can click [any file](https://github.com/bitraf/web/tree/master/) in this repository,
+and then hit the *pencil icon* on the file toolbar to edit. More documentation [here](https://help.github.com/articles/editing-files-in-your-repository/).
+
+To edit the frontpage, here is link to edit [index.php](https://github.com/bitraf/web/edit/master/index.php)
+
+One you have made the change, add a description of what you did "Fixed typo", and hit *Commit*.
+
+## Deploy changes
+
+[TODO: automate deployment](https://github.com/bitraf/web/issues/6)
+
+Log in to the server
+
+  ssh bitraf.no
+
+Pull the changes into staging
+
+  cd /home/bitweb/web/staging
+  git pull
+
+Check on staging that everything looks good: https://bitraf.no:4433/
+
+  # all good?
+
+Pull the changes into live
+
+  cd /home/bitweb/web/staging
+  git pull
+
+Double-check the changes on live site: https://bitraf.no
+
+
+## Using your own clone (advanced)
+
+The steps above assumes you made the changes directly in the main repository (https://github.com/bitraf/web).
+If you used your own clone, you can easily work with it by adding another git remote: `git remote add jonnor MY-CLONE-URL`, and do `git checkout jonnor/mybranch`. NB: Remember to always push your changes to main repo when you're happy with them!
