 Bash-based tests, to be ported to Python:
 -----------------------------------------
-- wallet.sh : Exercise wallet send/receive code.
-- walletbackup.sh : Exercise wallet backup / dump / import
-- txnmall.sh : Test proper accounting of malleable transactions
 - conflictedbalance.sh : More testing of malleable transaction handling
 
 Notes
 =====
 
+You can run a single test by calling `qa/pull-tester/rpc-tests.sh <testname>`.
+
+Run all possible tests with `qa/pull-tester/rpc-tests.sh -extended`.
+
+Possible options:
+
+````
+-h, --help       show this help message and exit
+  --nocleanup      Leave bitcoinds and test.* datadir on exit or error
+  --noshutdown     Don't stop bitcoinds after the test execution
+  --srcdir=SRCDIR  Source directory containing bitcoind/bitcoin-cli (default:
+                   ../../src)
+  --tmpdir=TMPDIR  Root directory for datadirs
+  --tracerpc       Print out all RPC calls as they are made
+```
+
+If you set the environment variable `PYTHON_DEBUG=1` you will get some debug output (example: `PYTHON_DEBUG=1 qa/pull-tester/rpc-tests.sh wallet`).

 A 200-block -regtest blockchain and wallets for four nodes
 is created the first time a regression test is run and
 is stored in the cache/ directory. Each node has 25 mature
