-### Upgrading
+## Version checking
+
+By default, `ts-jest` supports a range of versions for `jest`/`typescript`. One uses incompatible versions will receive a warning
+message while running tests. This warning message can be opt-out by setting environment variable `TS_JEST_DISABLE_VER_CHECKER`:
+
+**Linux/MacOS**
+
+```
+export TS_JEST_DISABLE_VER_CHECKER=true
+```
+
+**Windows**
+
+```
+set TS_JEST_DISABLE_VER_CHECKER=true
+```
+
+### Note
+
+As long as the environment variable `TS_JEST_DISABLE_VER_CHECKER` stays, the warning message will no longer show.
+This can lead to unexpected errors due to the usage of incompatible versions' dependencies. Use this environment variable with precautions.
+
+## Upgrading
 
 You can use the `config:migrate` tool of `ts-jest` CLI if you're coming from an older version to help you migrate your Jest configuration.
