+### Build xorm and test it locally
+
+Once you write some codes on your feature branch, you could build and test locally at first. Just
+
+```
+make build
+```
+and
+```
+make test
+```
+
+The `make test` is an alias of `make test-sqlite`, it will run the tests on a sqlite database file. No extra thing needed to do except you need to cgo compile enviroment.
+
+If you write a new test method, you could run
+
+```
+make test-sqlite#TestMyNewMethod
+```
+
+that will only run the special test method.
+
+If you want to run another datase, you have to prepare a running database at first, and then, you could
+
+```
+TEST_MYSQL_HOST= TEST_MYSQL_CHARSET= TEST_MYSQL_DBNAME= TEST_MYSQL_USERNAME= TEST_MYSQL_PASSWORD= make test-mysql
+```
+
+or other databases:
+```
+TEST_MSSQL_HOST= TEST_MSSQL_DBNAME= TEST_MSSQL_USERNAME= TEST_MSSQL_PASSWORD= make test-mssql
+```
+```
+TEST_PGSQL_HOST= TEST_PGSQL_SCHEMA= TEST_PGSQL_DBNAME= TEST_PGSQL_USERNAME= TEST_PGSQL_PASSWORD= make test-postgres
+```
+```
+TEST_TIDB_HOST= TEST_TIDB_DBNAME= TEST_TIDB_USERNAME= TEST_TIDB_PASSWORD= make test-tidb
+```
+
+And if your branch is related with cache, you could also enable it via `TEST_CACHE_ENABLE=true`.

+## Notice
+
+v1.0.0 相对于 v0.8.2 有以下不兼容的变更：
+
+- 移除了部分不符合Go语言命名的函数，如 `Id`, `Sql`，请使用 `ID`, `SQL` 替代。
+- 删除了对 `xorm.io/core` 的依赖。大部分代码迁移到了 `xorm.io/xorm/core`, `xorm.io/xorm/names`, `xorm.io/xorm/schemas` 等等几个包中.
+- 重命名了几个结构体，如： `core.IMapper` -> `names.Mapper`, `core.ILogger` -> `log.Logger`.
+
