 From an HTTP semantics point of view, using headers to convey the API version is the 'purer' approach. But from a user-experience point of view, using a URL prefix is arguably better. It makes it possible for developers to see which version of the API is being used at a glance, and it also means that the API can still be explored using a regular web browser (which is harder if custom headers are required).
 
+## SQL Migrations
+
+The first thing we need to do is generate a pair of _migration files_ using the **migrate create** command :
+
+```bash
+migrate create -seq -ext=.sql -dir=./migrations create_movies_table
+```
+
+In this command:  
+
+- The **-seq** flag indicates that we want to use sequential numbering like **0001, 0002, ...** for the migration files (instead of a Unix timestamp, which is the default).
+- The **-ext** flag indicates that we want to give the migration files the extension **.sql**.
+- The **-dir** flag indicates that we want to store the migration files in the **./migrations** directory (which will be created automatically if it doesn't already exist).
+- The name **create_movies_table** is a descriptive label that we give the migration files to signify their contents.
