-A micro framework in PHP for managing a set of database migrations using pure Sql.
+Simple library in PHP for database version control. Supports Sqlite, MySql, Sql Server and Postgres.
 
 Database Migration is a set of commands for upgrade or downgrade a database.
 This library uses only SQL commands.

+### Multi Development environment 
+
+If you work with multiple developers and multiple branches it is to difficult to determine what is the next number.
+
+In that case you have the suffix "-dev" after the version number. 
+
+See the scenario:
+
+- Developer 1 create a branch and the most recent version in e.g. 42.
+- Developer 2 create a branch at the same time and have the same database version number.
+
+In both case the developers will create a file called 43-dev.sql. Both developers will migrate UP and DOWN with
+no problem and your local version will be 43. 
+
+But developer 1 merged your changes and created a final version 43.sql (`git mv 43-dev.sql 43.sql`). If the developer 2
+update your local branch he will have a file 43.sql (from dev 1) and your file 43-dev.sql. 
+If he is try to migrate UP or DOWN
+the migration script will down and alert him there a TWO versions 43. In that case, developer 2 will have to update your
+file do 44-dev.sql and continue to work until merge your changes and generate a final version.
