+UTI outputs come in filesystem tree structure (single tree), where directories
+correspond to suite levels and files correspond to suite setup, suite teardown
+or any test case at this level of suite.
+The directory name comes from SUITE_NAME Robot variable (the last part
+as the previous parts are higher level suites), converted to lowercase.
+If the suite name contains spaces (Robot converts underscores to spaces),
+they are replaced with underscores.
+
+The filesystem tree is rooted under tests/ (as suites in git are there),
+and for each component (test case, suite setup, suite teardown).
+
+Although we expect only ASCII text in the exported files,
+we manipulate files using UTF-8 encoding,
+so if Robot Framework uses a non-ascii character, it will be handled.
+
+JSON schemas
+------------
+
+CSIT model is formally defined as a collection of JSON schema documents,
+one for each output file type.
+
+The current version specifies only one output file type:
+Info output for test case.
+
+The authoritative JSON schema documents are in JSON format.
+Git repository also contains YAML formatted document and conversion utility,
+which simplifies maintaining of the JSON document
+(no need to track brackets and commas), but are not authoritative.
