-focus and feats:
-****************
-fitting with these tenets, we're always open to new
-framework/lib/service interop suggestions and ideas!
+focus and features:
+*******************
+- 100% federated: your code, your hardware, your data feeds, your broker fills.
+- zero web: low latency, native software that doesn't try to re-invent the OS
+- maximal **privacy**: prevent brokers and mms from knowing your
+  planz; smack their spreads with dark volume.
+- zero clutter: modal, context oriented UIs that echew minimalism, reduce
+  thought noise and encourage un-emotion.
+- first class parallelism: built from the ground up on next-gen structured concurrency
+  primitives.
+- traders first: broker/exchange/asset-class agnostic
+- systems grounded: real-time financial signal processing that will
+  make any queuing or DSP eng juice their shorts.
+- non-tina UX: sleek, powerful keyboard driven interaction with expected use in tiling wms
+- data collaboration: every process and protocol is multi-host scalable.
+- fight club ready: zero interest in adoption by suits; no corporate friendly license, ever.
 
-- **100% federated**:
-  your code, your hardware, your data feeds, your broker fills.
+fitting with these tenets, we're always open to new framework suggestions and ideas.
 
-- **zero web**:
-  low latency as a prime objective, native UIs and modern IPC

-
-- **maximal privacy**:
-  prevent brokers and mms from knowing your planz; smack their
-  spreads with dark volume from a VPN tunnel.

-- **zero clutter**:
-  modal, context oriented UIs that echew minimalism, reduce thought
-  noise and encourage un-emotion.
-
-- **first class parallelism**:
-  built from the ground up on a next-gen structured concurrency
-  supervision sys.

-- **systems grounded**:
-  real-time financial signal processing (fsp) that will make any
-  queuing or DSP eng juice their shorts.
-
-- **non-tina UX**:
-  sleek, powerful keyboard driven interaction with expected use in
-  tiling wms (or maybe even a DDE).
-

-a sane install with `uv`
-************************
-bc why install with `python` when you can faster with `rust` ::
-
-    uv sync
-
-    # ^ astral's docs,
-    # https://docs.astral.sh/uv/concepts/projects/sync/
-
-include all GUIs (ex. for charting)::
-
-    uv sync --group uis
-
-AND with **all** our normal hacking tools::
-
-    uv sync --dev
-
-AND if you want to try WIP integrations::
-
-    uv sync --all-groups
-
-Ensure you can run the root-daemon::
-
-    uv run pikerd [-l info --pdb]
+sane install with `poetry`

+TODO!
 
 
-install on nix(os)
-******************
-``NixOS`` is our core devs' distro of choice for which we offer
-a stringently defined development shell envoirment that can currently
-be applied in one of 2 ways::
-
-    # ONLY if running on X11
-    nix-shell default.nix
-
-Or if you prefer flakes style and a modern DE::
-
-    # ONLY if also running on Wayland
-    nix develop  # for default bash
-    nix develop -c uv run xonsh  # for @goodboy's preferred sh B)
+rigorous install on ``nixos`` using ``poetry2nix``

+TODO!
 
 
-start a chart
-*************
-run a realtime OHLCV chart stand-alone::
+hacky install on nixos
+**********************
+`NixOS` is our core devs' distro of choice for which we offer
+a stringently defined development shell envoirment that can be loaded with::
 
-    [uv run] piker -l info chart btcusdt.spot.binance xmrusdt.spot.kraken
+    nix-shell develop.nix
 
-    # ^^^ iff you haven't activated the py-env,
-    # - https://docs.astral.sh/uv/concepts/projects/run/
-    #
-    # in order to create an explicit virt-env see,
-    # - https://docs.astral.sh/uv/concepts/projects/layout/#the-project-environment
-    # - https://docs.astral.sh/uv/pip/environments/
-    #
-    # use $UV_PROJECT_ENVIRONMENT to select any non-`.venv/`
-    # as the venv sudir in the repo's root.
-    # - https://docs.astral.sh/uv/reference/environment/#uv_project_environment
+this will setup the required python environment to run piker, make sure to
+run::
 
-this runs a chart UI (with 1m sampled OHLCV) and shows 2 spot markets from 2 diff cexes
-overlayed on the same graph. Use of `piker` without first starting
-a daemon (`pikerd` - see below) means there is an implicit spawning of the
-multi-actor-runtime (implemented as a `tractor` app).
+    pip install -r requirements.txt -e .
 
-For additional subsystem feats available through our chart UI see the
-various sub-readmes:
-
-- order control using a mouse-n-keyboard UX B)
-- cross venue market-pair (what most call "symbol") search, select, overlay Bo
-- financial-signal-processing (`piker.fsp`) write-n-reload to sub-chart BO
-- src-asset derivatives scan for anal, like the infamous "max pain" XO
+once after loading the shell
 
 
-spawn a daemon standalone
-*************************
-we call the root actor-process the ``pikerd``. it can be (and is
-recommended normally to be) started separately from the ``piker
-chart`` program::
+install wild-west style via `pip`
+*********************************
+``piker`` is currently under heavy pre-alpha development and as such
+should be cloned from this repo and hacked on directly.
+
+for a development install::
+
+    git clone git@github.com:pikers/piker.git
+    cd piker
+    virtualenv env
+    source ./env/bin/activate
+    pip install -r requirements.txt -e .
+
+
+check out our charts
+********************
+bet you weren't expecting this from the foss::
+
+    piker -l info -b kraken -b binance chart btcusdt.binance --pdb
+
+
+this runs the main chart (currently with 1m sampled OHLC) in in debug
+mode and you can practice paper trading using the following
+micro-manual:
+
+``order_mode`` (
+    edge triggered activation by any of the following keys,
+    ``mouse-click`` on y-level to submit at that price
+    ):
+
+    - ``f``/ ``ctl-f`` to stage buy
+    - ``d``/ ``ctl-d`` to stage sell
+    - ``a`` to stage alert
+
+
+``search_mode`` (
+    ``ctl-l`` or ``ctl-space`` to open,
+    ``ctl-c`` or ``ctl-space`` to close
+    ) :
+
+    - begin typing to have symbol search automatically lookup
+      symbols from all loaded backend (broker) providers
+    - arrow keys and mouse click to navigate selection
+    - vi-like ``ctl-[hjkl]`` for navigation
+
+
+you can also configure your position allocation limits from the
+sidepane.
+
+
+run in distributed mode
+***********************
+start the service manager and data feed daemon in the background and
+connect to it::
 
     pikerd -l info --pdb
 
-the daemon does nothing until a ``piker``-client (like ``piker
-chart``) connects and requests some particular sub-system. for
-a connecting chart ``pikerd`` will spawn and manage at least,
 
-- a data-feed daemon: ``datad`` which does all the work of comms with
-  the backend provider (in this case the ``binance`` cex).
-- a paper-trading engine instance, ``paperboi.binance``, (if no live
-  account has been configured) which allows for auto/manual order
-  control against the live quote stream.
+connect your chart::
 
-*using* an actor-service (aka micro-daemon) manager which dynamically
-supervises various sub-subsystems-as-services throughout the ``piker``
-runtime-stack.
+    piker -l info -b kraken -b binance chart xmrusdt.binance --pdb
 
-now you can (implicitly) connect your chart::
 
-    piker chart btcusdt.spot.binance
-
-since ``pikerd`` was started separately you can now enjoy a persistent
-real-time data stream tied to the daemon-tree's lifetime. i.e. the next
-time you spawn a chart it will obviously not only load much faster
-(since the underlying ``datad.binance`` is left running with its
-in-memory IPC data structures) but also the data-feed and any order
-mgmt states should be persistent until you finally cancel ``pikerd``.
+enjoy persistent real-time data feeds tied to daemon lifetime. the next
+time you spawn a chart it will load much faster since the data feed has
+been cached and is now always running live in the background until you
+kill ``pikerd``.

-Connecting to the API from `piker`
----------------------------------
-In order to expose the container's API endpoint to the
-`brokerd/datad/ib` actor, we need to add a section to the user's
-`brokers.toml` config (note the below is similar to the repo-shipped
-template file),
-
-.. code:: toml
-
-    [ib]
-    # define the (set of) host-port socketaddrs that
-    # brokerd.ib will scan to connect to an API endpoint
-    # (ib-gw or ib-tws listening instances)
-    hosts = [
-        '127.0.0.1',
-    ]
-    ports = [
-        4002,  # gw
-        7497,  # tws
-    ]
-
-    # When API endpoints are being scanned durin startup, the order
-    # of user-defined-account "names" (as defined below) here
-    # determines which py-client connection is given priority to be
-    # used for data-feed-requests by according to whichever client
-    # connected to an API endpoing which reported the equivalent
-    # account number for that name.
-    prefer_data_account = [
-        'paper',
-        'margin',
-        'ira',
-    ]
-
-    # define "aliases" (names) for each account number
-    # such that the names can be reffed and logged throughout
-    # `piker.accounting` subsys and more easily
-    # referred to  by the user.
-    #
-    # These keys will be the set exposed through the order-mode
-    # account-selection UI so that numbers are never shown.
-    [ib.accounts]
-    paper = 'XX0000000'
-    margin = 'X0000000'
-    ira = 'X0000000'
-
-
-the broker daemon can also connect to the container's VNC server for
-added functionalies including,
-
-- viewing the API endpoint program's GUI for manual interventions,
-- workarounds for historical data throttling using hotkey hacks,
-
-Add a further section to `brokers.toml` which maps each API-ep's
-port to a table of VNC server connection info like,
-
-.. code:: toml
-
-    [ib.vnc_addrs]
-    4002 = {host = 'localhost', port = 5900, pw = 'doggy'}
-
-The `pw = 'doggy'` here ^ should the same value as the particular
-container instances `.env` file setting (when it was run),
-
-.. code:: ini
-
-    VNC_SERVER_PASSWORD='doggy'
-
-
-IF you also want to run ``TWS``
--------------------------------
-You can also run it containerized,
-
-https://github.com/gnzsnz/ib-gateway-docker?tab=readme-ov-file#using-tws
-
-
-SECURITY stuff (advanced, only if you're paranoid)
---------------------------------------------------
-First and foremost if doing a "distributed" container setup where you
-run the ``ib-gw`` docker container and your connecting API client
-(likely ``ib_async`` from python) on **different hosts** be sure to
-read the `security considerations`_ section!
-
-And for a further (somewhat paranoid) perspective from
-a long-time-ago serious devops eng..
-
-Though "``ib``" claims they filter remote host connections outside
-``localhost`` (aka ``127.0.0.1`` on ipv4) it's prolly justified if
-you'd like to filter the socket at the *OS level* using a stateless
-firewall rule::
+SECURITY STUFF!?!?!
+-------------------
+Though "``ib``" claims they host filter connections outside
+localhost (aka ``127.0.0.1``) it's probably better if you filter
+the socket at the OS level using a stateless firewall rule::
 
     ip rule add not unicast iif lo to 0.0.0.0/0 dport 4002
 
-
-We will soon have this either baked into our own custom derivative
-image (or patched into the current upstream one after further testin)
-but for now you'll have to do it urself, diggity dawg.

-broker and data provider.

-avail UIs
-*********
-
-order ctl
----------
-the `piker.clearing` subsys is exposed mainly though
-the `piker chart` GUI as a "chart trader" style UX and
-is automatically enabled whenever a chart is opened.
-
-.. ^TODO, more prose here!
-
-the "manual" order control features are exposed via the
-`piker.ui.order_mode` API and can pretty much always be
-used (at least) in simulated-trading mode, aka "paper"-mode, and
-the micro-manual is as follows:
-
-``order_mode`` (
-    edge triggered activation by any of the following keys,
-    ``mouse-click`` on y-level to submit at that price
-    ):
-
-    - ``f``/ ``ctl-f`` to stage buy
-    - ``d``/ ``ctl-d`` to stage sell
-    - ``a`` to stage alert
-
-
-``search_mode`` (
-    ``ctl-l`` or ``ctl-space`` to open,
-    ``ctl-c`` or ``ctl-space`` to close
-    ) :
-
-    - begin typing to have symbol search automatically lookup
-      symbols from all loaded backend (broker) providers
-    - arrow keys and mouse click to navigate selection
-    - vi-like ``ctl-[hjkl]`` for navigation
-
-
-position (pp) mgmt
-------------------
-you can also configure your position allocation limits from the
-sidepane.
-
-.. ^TODO, explain and provide tut once more refined!

-'''
-Programmatic debugging helper for `pdbp` REPL human-like
-interaction but built to allow `claude` to interact with 
-crashes and `tractor.pause()` breakpoints along side a human dev.
-
-Originally written by `clauded` during a backfiller inspection
-session with @goodboy trying to resolve duplicate/gappy ohlcv ts
-issues discovered while testing the new `nativedb` tsdb.
-
-Allows `claude` to run `pdb` commands and capture output in an "offline"
-manner but generating similar output as if it was iteracting with
-the debug REPL.
-
-The use of `pexpect` is heavily based on tractor's REPL UX test
-suite(s), namely various `tests/devx/test_debugger.py` patterns.
