+Running the bindingstester
+===
+
+This assumes that all FoundationDB dependencies are installed properly. See
+the FoundationDB documentation for information on the dependencies.
+
+1. Download and build FoundationDB
+---
+
+```bash
+$ git clone https://github.com/apple/foundationdb
+$ cd foundationdb
+$ # Optionally checkout a specific release branch
+$ # git checkout -b release-6.1 origin/release-6.1
+$ mkdir _build
+$ cd _build
+$ cmake ..
+$ make -j4
+```
+
+2. Tweak `bindingtester` to be able to run our Erlang client
+---
+
+```bash
+$ cd ../bindings/bindingtester
+$ vi __init__.py # Comment out the sys.path injection on line 25
+$ vi known_testers.py # Add the following line to the `testers` hash
+```
+
+```python
+'erlang': Tester('erlang', '/Users/davisp/github/labs-cloudant/couchdb-erlfdb/test/tester.es', 2040, MAX_API_VERSION, MAX_API_VERSION, types=ALL_TYPES),
+```
+
+3. Start a temporary fdbserver instance
+---
+
+*This should be done in a second shell*
+
+```bash
+$ mkdir ~/tmp/fdbtest
+$ cd ~/tmp/fdbtest
+$ echo "foo:bar@127.0.0.1:4689" > fdb.cluster
+$ /Users/davisp/github/davisp/foundationdb/_build/bin/fdbserver \
+ -p 127.0.0.1:4689 \
+ -C fdb.cluster \
+ -d . \
+ -L .
+```
+
+4. Configure the temporary fdbserver instance
+---
+
+*This only needs to be done once after step 3*
+
+```bash
+$ cd ~/tmp/fdbtest
+$ /Users/davisp/github/davisp/foundationdb/_build/bin/fdbcli
+Database created
+```
+
+5. Start the binding test
+---
+
+*Notice that the ERL_LIBS=... command is one long single line.*
+
+```bash
+$ cd /Users/davisp/github/davisp/foundationdb/bindings/bindingtester
+$ ERL_LIBS=/Users/davisp/github/labs-cloudant/couchdb-erlfdb/ PYTHONPATH=/Users/davisp/github/davisp/foundationdb/_build/bindings/python/ ./bindingtester.py --cluster-file /Users/davisp/tmp/fdbtest/fdb.cluster erlang
+```
+
+By default, `bindingtester.py` runs the `scripted.py` test which is a deterministic set of tests. To really try and soak test the bindings you should add the following command line parameters:
+
+`--test-name api --num-ops 10000`
+
+The `api` test is a large randomly generated set of test instructions and should exercise a number of combinations of parameters exercising large portions of the bindings.
+
+If you do encounter an error in tests you can add these options to try and debug the issue:
+
+`--seed $SEED --bisect`
+
+Where `$SEED` is printed in the output of the failed test run.

+Binding Tester
+---
+
+FoundationDB has a custom binding tester that can be used to test whether
+changes have broken compatibility. See the [BINDING_TESTER](BINDING_TESTER.md)
+documentation for instructions on building and running that system.
