-`csp` ("Composable Stream Processing") is a functional-like reactive
-language that makes time-series stream processing simple to do.  The
-main reactive engine is a C++ based engine which has been exposed to
-python ( other languages may optionally be extended in future versions
-). `csp` applications define a connected graph of components using a
-declarative language (which is essentially python).  Once a graph is
-constructed it can be run using the C++ engine. Graphs are composed of
-some number of "input" adapters, a set of connected calculation "nodes"
-and at the end sent off to "output" adapters. Inputs as well as the
-engine can be seamlessly run in simulation mode using historical input
-adapters or in realtime mode using realtime input adapters.

-# Roadmap
-
-We do not have a formal roadmap, but we're happy to discuss features, improvements, new adapters, etc, in our [discussions area](https://github.com/Point72/csp/discussions). Here are some high level items we hope to accomplish in the next few months:
-
-- Support `clang` compiler and full MacOS support ([#33](https://github.com/Point72/csp/issues/33) / [#132](https://github.com/Point72/csp/pull/132))
-- Support `msvc` compiler and full Windows support ([#109](https://github.com/Point72/csp/issues/109))
-- Establish a better pattern for adapters ([#165](https://github.com/Point72/csp/discussions/165))
-
-## Adapters and Extensions
-
-- Redis Pub/Sub Adapter with [Redis-plus-plus](https://github.com/sewenew/redis-plus-plus) ([#61](https://github.com/Point72/csp/issues/61))
-- C++-based websocket adapter
-  - Client adapter in [#152](https://github.com/Point72/csp/pull/152)
-- C++-based HTTP/SSE adapter
-- Add support for other graph viewers, including interactive / standalone / Jupyter
-
-## Other Open Source Projects
-
-- `csp-gateway`: Application development framework, built with [FastAPI](https://fastapi.tiangolo.com) and [Perspective](https://github.com/finos/perspective). This is a library we have built internally at Point72 on top of `csp` that we hope to open source later in 2024. It allows for easier construction of modular `csp` applications, along with a pluggable REST/WebSocket API and interactive UI.

+`csp.baselib` defines some generally useful adapters, which are also imported directly into the CSP namespace when importing CSP.
+
+These are all graph-time constructs.

+
+## `csp.timer`
+
+```python
+csp.timer(
+    interval: timedelta,
+    value: '~T' = True,
+    allow_deviation: bool = False
+)
+```
+
+This will create a repeating timer edge that will tick on the given `timedelta` with the given value (value defaults to `True`, returning a `ts[bool]`)
+
+Args:
+
+- **`interval`**: how often to tick value
+- **`value`**: the actual value that will tick every interval (defaults to the value `True`)
+- **`allow_deviation`**: When running in realtime the engine will ensure timers execute exactly when they requested on their intervals.
+  If your engine begins to lag, timers will still execute at the expected time "in the past" as the engine catches up
+  (imagine having a `csp.timer` fire every 1/2 second but the engine becomes delayed for 1 second.
+  By default the half seconds will still execute until time catches up to wallclock).
+  When `allow_deviation` is `True`, and the engine is in realtime mode, subsequent timers will always be scheduled from the current wallclock + interval,
+  so they won't end up lagging behind at the expensive of the timer skewing.
+
+## `csp.const`
+
+```python
+csp.const(
+    value: '~T',
+    delay: timedelta = timedelta()
+)
+```
+
+This will create an edge that ticks one time with the value provided.
+By default this will tick at the start of the engine, delta can be provided to delay the tick
+
+## `csp.curve`
+
+```python
+csp.curve(
+    typ: 'T',
+    data: typing.Union[list, tuple]
+)
+```
+
+This allows you to convert a list of non-CSP data into a ticking edge in CSP
+
+Args:
+
+- **`typ`**: is the type of the value of the data of this edge
+- **`data`**: is either a list of tuples of `(datetime, value)`, or a tuple of two equal-length numpy ndarrays, the first with datetimes and the second with values.
+  In either case, that will tick on the returned edge into the engine, and the data must be in time order.
+  Note that for the list of tuples case, you can also provide tuples of (timedelta, value) where timedelta will be the offset from the engine's start time.
+
+## `csp.add_graph_output`
+
+```python
+csp.add_graph_output(
+    key: object,
+    input: ts['T'],
+    tick_count: int = -1,
+    tick_history: timedelta = timedelta()
+)
+```
+
+This allows you to connect an edge as a "graph output".
+All edges added as outputs will be returned to the caller from `csp.run` as a dictionary of `key: [(datetime, value)]`
+(list of datetime, values that ticked on the edge) or if `csp.run` is passed `output_numpy=True`, as a dictionary of
+`key: (array, array)` (tuple of two numpy arrays, one with datetimes and one with values).
+See [Collecting Graph Outputs](https://github.com/Point72/csp/wiki/0.-Introduction#collecting-graph-outputs)
+
+Args:
+
+- **`key`**: key to return the results as from `csp.run`
+- **`input`**: edge to connect
+- **`tick_count`**: number of ticks to keep in the buffer (defaults to -1 - all ticks)
+- **`tick_history`**: amount of ticks to keep by time window (defaults to keeping all history)
+
+## `csp.feedback`
+
+```python
+csp.feedback(typ)
+```
+
+`csp.feedback` is a construct that can be used to create artificial loops in the graph.
+Use feedbacks in order to delay bind an input to a node in order to be able to create a loop
+(think of writing a simulated exchange that takes orders in and needs to feed responses back to the originating node).
+
+`csp.feedback` itself is not an edge, its a construct that allows you to access the delayed edge / bind a delayed input.
+
+Args:
+
+- **`typ`**: type of the edge's data to be bound
+
+Methods:
+
+- **`out()`**: call this method on the feedback object to get the edge which can be wired as an input
+- **`bind(x: ts[object])`**: call this to bind an edge to the feedback
