-In order to reproduce benchmark results, one should first generate input data.
-Random data can be generated with the following programs (written in haskell):
+To run benchmarks:
 
-    http/gen/gen_http.hs
-    uri/gen/gen_uri.hs
+1. Create symlink to the RE2C binary (version 1.0 or older) in the current
+directory.
 
-Use the following scripts to build generators:
+2. Generate input data: files ./http/gen/http.dat and ./uri/gen/uri.dat.
+    Random data can be generated with the following programs (written in
+    haskell):
 
-    http/gen/mk_gen.sh
-    uri/gen/mk_gen.sh
+        http/gen/gen_http.hs
+        uri/gen/gen_uri.hs
 
-The size of the generated data is hard-coded in the source code of generators
-(and can be easily tweaked).
+    Use the following scripts to build generators:
+
+        http/gen/mk_gen.sh
+        uri/gen/mk_gen.sh
+
+    The size of the generated data is hard-coded in the source code of
+    generators (and can be easily tweaked).
+
+    Alternatively, if you don't have haskell compiler or for any other reason
+    are unable to build generators, use small data samples provided for each
+    benchmark (one can copy-paste them many times with 'cat' to obtain a large
+    input file):
+
+        http/gen/sample.dat
+        uri/gen/sample.dat

+    ./uri/rfc3986/__bench_b.sh
+    ./uri/rfc3986/__bench_unopt.sh

+    Alternatively, run ./__run.sh (it will drop logs in each subdirectory).
