- CitrineOS core extracted (CSMS OCPP 2.0.1)
- OpenOCPP extracted (firmware OCPP 1.6J/2.0.1)
- ShapeShifter library installed (pip install -e)
- ShapeShifter specification extracted
- EVerest extracted

+# Tests
+
+Building tests:
+
+```sh
+$ cd EVerest
+$ mkdir build
+$ cd build
+$ cmake -GNinja -DEVEREST_CORE_BUILD_TESTING=ON ..
+$ ninja install
+```
+
+`touch release.json` may be needed if it hasn't been created
+(then re-run `ninja install`).
+
+## Run EVerest in SIL
+
+1. start MQTT broker
+2. from `build/run-scripts` run `./run-sil-dc-tls.sh`
+3. from `build/run-scripts` run `./nodered-sil-dc.sh`
+4. open web browser [EVerest Node-RED dashboard](http://localhost:1880/ui/)
+
+## Unit tests
+
+- `./v2g_openssl_test`
+- automatically runs `pki.sh`
+- run from the directory containing the executable
+
+### Standalone V2G TLS server
+
+Tests the Server class via the functions in connection.cpp and
+tls_connection.cpp.
+
+- `./v2g_server -i <interface name>`
+- connects to IPv6 only with a link local address
+- requires `boost` library so LD_LIBRARY_PATH may need to be set
+- displays the address it is listening on. e.g.
+  `[fe80::ae91:a1ff:fec9:a947%3]:64109`
+- supports multiple connections
+- gracefully terminates after 80 seconds
+- `valgrind` can be used to check memory allocations
+  (has some leaks - possibly in v2g_ctx_start_events thread)
+- requires client certificate
+- s_client echos back what is typed with a delay since V2G has a long timeout
+
+The connect argument must match what was displayed by `v2g_server`
+
+```sh
+openssl s_client -connect [fe80::ae91:a1ff:fec9:a947%3]:64109 -verify 2 -CAfile server_root_cert.pem -cert client_cert.pem -cert_chain client_chain.pem -key client_priv.pem -verify_return_error -verify_hostname evse.pionix.de -status
