 _go-sqlite3_ is *cgo* package.
 If you want to build your app using go-sqlite3, you need gcc.
 However, if you install _go-sqlite3_ with `go install github.com/mattn/go-sqlite3`, you don't need gcc to build your app anymore.

+* Can I use this in multiple routines concurrently?
+
+    Yes for readonly. But, No for writable. See [#50](https://github.com/mattn/go-sqlite3/issues/50), [#51](https://github.com/mattn/go-sqlite3/issues/51), [#209](https://github.com/mattn/go-sqlite3/issues/209).
+
+* Why is it racy if I use a `sql.Open("sqlite3", ":memory:")` database?
+
+    Each connection to :memory: opens a brand new in-memory sql database, so if
+    the stdlib's sql engine happens to open another connection and you've only
+    specified ":memory:", that connection will see a brand new database. A
+    workaround is to use "file::memory:?mode=memory&cache=shared". Every
+    connection to this string will point to the same in-memory database. See
+    [#204](https://github.com/mattn/go-sqlite3/issues/204) for more info.
