+# GoBlog's storage system
+
+## Database
+
+GoBlog uses a SQLite database for storing most of the data (posts, comments, webmention, sessions, etc.). The database is accessed using the Go library [mattn/go-sqlite3](https://github.com/mattn/go-sqlite3). With each startup it is checked if there are schema migrations to be performed on the database.
+
+Currently there are the following database tables:
+
+```
+activitypub_followers
+comments
+deleted
+indieauthauth
+indieauthtoken
+migrations
+notifications
+persistent_cache
+post_parameters
+posts
+posts_fts
+queue
+sessions
+shortpath
+webmentions
+```
