+Diachronic morphosyntactic disambiguation challenge
+===================================================
+
+The task is to take part in "Diachronic morphosyntactic
+disambiguation" challenge:
+http://poleval2020.nlp.ipipan.waw.pl/challenge/poleval-diachronic-morpho
+
+Also, apart from submitting a solution you're expected to report any
+problems with the web site (including incorrect English, unclear
+instructions, software errors).
+
+For an account there, please contact Filip Graliński, but do it only
+when you're sure you'll take part in it — the dataset and instructions
+are freely available without a need to sign up there:
+git://poleval2020.nlp.ipipan.waw.pl/poleval-diachronic-morpho
+http://poleval2020.nlp.ipipan.waw.pl/challenge-readme/poleval-diachronic-morpho
+http://poleval2020.nlp.ipipan.waw.pl/challenge-how-to/poleval-diachronic-morpho
+
+This is a special task, Jenkins/make won't be used. The task will be
+scored manually, according to the following criteria:
+
+* submitting a solution beating a simple baseline along with the
+  source codes: 4 points
+* quality of solution (including the result obtained): 0-8
+* quality of usage report (0-6 points)
+
+In Section A (contrary to B/C) points are *added* (it is not the case
+the maximum is calculated).
