+About placing SQL files:
+
+File should be named `V1000_{version}__{description}.sql` where:
+- `{version}` is the sequential ID, please pick the next available number
+- `{description}` is a short description of the change
+
+The folders are grouped by 40 changes each, please put the files in the correct folder according to the version number:
+- `db/40` : 1-40
+- `db/80` : 41-80
+- etc.
+
+(this is to avoid having to scroll through a huge list of files when looking for a specific change)
