+`github.com/pressly/goose` is a fork of `bitbucket.org/liamstask/goose` with the following changes:
 - No config files
 - [Default goose binary](./cmd/goose/main.go) can migrate SQL files only
 - Go migrations:
-    - We dropped building Go migrations on-the-fly from .go source files
-    - Instead, you can create your own goose binary, import `github.com/pressly/goose`
-      package and run complex Go migrations with your own `*sql.DB` connection
-    - Each Go migration function is called with `*sql.Tx` argument - within its own transaction
-- The goose pkg is decoupled from the default binary:
-    - goose pkg doesn't register any SQL drivers anymore
-      (no driver `panic()` conflict within your codebase!)
+    - We don't `go build` Go migrations functions on-the-fly
+      from within the goose binary
+    - Instead, we let you
+      [create your own custom goose binary](examples/go-migrations),
+      register your Go migration functions explicitly and run complex
+      migrations with your own `*sql.DB` connection
+    - Go migration functions let you run your code within
+      an SQL transaction, if you use the `*sql.Tx` argument
+- The goose pkg is decoupled from the binary:
+    - goose pkg doesn't register any SQL drivers anymore,
+      thus no driver `panic()` conflict within your codebase!
     - goose pkg doesn't have any vendor dependencies anymore
+- We encourage using sequential versioning of migration files
+    (rather than timestamps-based versioning) to prevent version
+    mismatch and migration colissions
