+# Robosats traditional environment
+
+Robosats backend development and testing without docker and containers.
+
+Binaries needed:
+* postgresql (`postgres`, `initdb`, `psql`)
+* redis (`redis-server`)
+* bitcoin (`bitcoind`, `bitcoin-cli`)
+* cln (`lightningd`, `lightning-cli`, `holdinvoice`)
+* lnd (`lnd`, `lncli`)
+
+## Preparation
+
+Postgresql and redis can be found in all linux distros and bsds.
+
+Some distros do not put postgresql binaries in `PATH`, if this is the
+case simply link them somewhere in your `PATH`.
+
+Example on debian:
+```
+ln -sf /usr/lib/postgresql/16/bin/postgres ~/.local/bin/
+ln -sf /usr/lib/postgresql/16/bin/initdb ~/.local/bin/
+ln -sf /usr/lib/postgresql/16/bin/psql ~/.local/bin/
+```
+
+Bitcoin nodes if not already installed need to be manually downloaded.
+* bitcoin core binaries can be found here: https://bitcoincore.org/en/download
+* cln binaries can be found here: https://github.com/ElementsProject/lightning/releases
+* holdinvoice binary can be found here: https://github.com/daywalker90/holdinvoice/releases
+* lnd binaries can be found here: https://github.com/lightningnetwork/lnd/releases
+
+Example preparation:
+```
+$ python3 -m venv venv
+$ . venv/bin/activate
+$ pip install -r requirements_dev.txt
+$ pip install -r requirements.txt
+
+$ mkdir regtest
+$ mkdir regtest/programs
+$ cd regtest/programs
+$ mkdir bitcoin cln lnd
+# download bitcoin, cln (and holdinvoice) and lnd binaries
+
+# if you want to use roboauto
+# still in regtest/programs
+$ git clone https://github.com/jerryfletcher21/roboauto
+$ cd roboauto
+$ pip install -r requirements.txt
+$ pip install .
+```
+
+## env file
+
+```
+$ cp .env-sample .env
+```
+Edit `.env`, both robosats and regtest scripts will read from there.

+
+Paths can be relative or absolute. Binaries should be paths, they are
+not resolved with `PATH`.
+
+Roboauto can be disabled by not setting `ROBOAUTO_GIT_DIR` or setting it
+to `false`.
+
+If some ports are already in use, change their value.
+
+To check which port are already in use, `netstat -tulnp` with root
+privileges can be used.
+
+For example if there is alread an instance of postgresql running on the
+default port, change `POSTGRES_PORT = "5433"`.
+
+## Usage
+
+For development and testing two scripts are provided:
+* `regtest-services` for non bitcoin related services
+* `regtest-nodes` for bitcoin and lightning nodes
+
+`regtest-services` sets up the database and manages the services.
+
+Everything is done locally, so no root privileges/service managers are
+needed.
+
+`regtest-nodes` is a script that should be sourced, it sets up a regtest
+environment, with bitcoin core, cln, lnd and roboauto, connecting them
+and creating channels. It then exposes the functions `btc_reg`,
+`cln_coord`, `cln_user`, `lnd_coord`, `lnd_user`, `ra_reg` to interact
+with the nodes and roboauto.
+
+If the script is sourced in a `bash` shell, it will also source
+completions for all the functions.
+
+`regtest-nodes` can also be run without arguments to simply expose the
+functions to start and remove the nodes and to create the channels
+between them, without setting up a specific environment.
+
+Setup:
+```
+# after having changed .env file
+
+$ . venv/bin/activate
+
+# generate cln and lnd grpc
+$ scripts/generate_grpc.sh
+
+$ scripts/traditional/regtest-services postgres-setup
+
+$ scripts/traditional/regtest-services postgres-database
+
+# postgres-database will create the database specified by
+# POSTGRES_DB in .env, it can be run multiple times with
+# different values of POSTGRES_DB for different databases
+```
+
+Testing:
+```
+# edit .env setting LNVENDOR to either "CLN" or "LND"
+# LNVENDOR_ROBOT while running tests should be set to "LND"
+
+# in the main window
+$ . venv/bin/activate
+$ . scripts/traditional/regtest-nodes test
+
+# in a secondary window
+$ . venv/bin/activate
+# can be stopped with Control-C
+$ scripts/traditional/regtest-services test
+
+# back in the main window
+$ python3 manage.py test
+
+# after having run the tests run
+$ robosats_regtest_stop_and_remove_all
+# to remove the nodes, they will be recreated when
+# running the tests again
+
+# the tests should be run with a clean database so if you have already run
+# the server and want to keep the database, either use a different value
+# of POSTGRES_DB or use a different directory by moving
+# regtest/services/postgres somewhere and the moving it back when you want
+# to run the server again
+```
+
+Development:
+```
+# edit .env setting LNVENDOR to either "CLN" or "LND"
+# and LNVENDOR_ROBOT to either "CLN" or "LND"
+
+# in the main window
+$ . venv/bin/activate
+$ . scripts/traditional/regtest-nodes server
+
+# in a secondary window
+$ . venv/bin/activate
+# can be stopped with Control-C
+$ scripts/traditional/regtest-services server
+
+# to see the output of the django runserver command
+# in a third window
+$ tail -f regtest/logs/runserver
+
+# if roboauto is active, use it to test the backend
+# back in the main window
