+Apiritif is a number of utilities aimed to simplify the process of maintaining API tests.
 Apiritif tests fully based on python nose tests. This library can help you to develop and run your existing tests.
 In order to create any valid tests for Apiritif you can read [nose test documentation](https://nose.readthedocs.io/en/latest/testing.html).
 
 Check Apiritif version with the following command:
-```

 Here is an example of certificate usage:

 At the same time requests to `users/all` page will be executed outside of transaction even if something inside transaction fails.
 
 Transaction defines the name for the block of code. This name with execution results of this particular block will be displayed in the output report.

 Also each transaction defines the name for the block of code and will be displayed in the output report.

 Now about `apiritif.put_into_thread_store(func_mode=True)`, this is test execution mode for apiritif.
 We can execute all of the transactions in test no matter what or stop after first failed transaction.
 This flag tells to apiritif "Stop execution if some transaction failed". `False` says "Run till the end in any case".

 If this test will be interrupted in `_method_with_exception`, both of teardown methods will be executed even if them raise exception.
 Please note two differences with usage of `tearDown` method of nose:
+
 1. all parts of teardown stage will be executed as mentioned above (will be interrupted in regular nose execution)
 2. results of teardown steps will be written by apiritif SampleWriter into output file (nose lost them as tearDown isn't recognised as test).
 
 ##### Graceful shutdown
+
 Somethimes waiting of end of test isn't necessary and we prefer to break it but save all current results and handle all teardown steps. (see above)
 It's possible with GRACEFUL flag. To use it you can run apiritif with GRACEFUL environment variable pointed to any file name.
 Apiritif will be interrupted as soon as the file is created.

 ### Environment Variables
 
 There are environment variables to control length of response/request body to be written into traces and logs:
-  * `APIRITIF_TRACE_BODY_EXCLIMIT` - limit of body part to include into exception messages, default is 1024
-  * `APIRITIF_TRACE_BODY_HARDLIMIT` - limit of body length to include into JSON trace records, default is unlimited
