+# The Xnoe Blog
+
+This is a highly work-in-progress blog frontend and backend written in Haskell and Elm-lang, using PostgreSQL for the database, it is being developed with a Docker-first mindset to make development a breeze.
+
+Currently the only functionality that exists is providing a really bad card view of the posts that exist.
+
+You will need to create a table called posts manually if you want to use this, the following is necessary
+
+```sql
+CREATE TABLE posts(title varchar(128), subtext varchar(128), category varchar(128));
+```
+
+And you will need to add any entries manually.
+
+Exposed on port 80
