 Reaction Systems Verification Toolkit
 
 The toolkit consists of two separate modules implementing:
-* Methods implemented using binary decision diagrams (BDD) for storing and manipulating the state space of the verified system.
+
+* Methods using binary decision diagrams (BDD) for storing and manipulating the state space of the verified system.
 * Methods translating the verification problems into satisfiability modulo theories (SMT).
 
-# Installation
-
-## Installing everything manually
-
-(to be added)
-
-## Virtual Machine
-
-The easiest way to try out ReactICS is to download [the VM where everything is alread installed](http://reactionsystems.org/ReactICS.zip). This a VirtualBox virtual machine. After booting it up, you can log in as `reactics` with the same password. After logging in, ReactICS is available in the `reactics` directory:
-
-```
-$ cd reactics
-```
-
-An update and setup needs to be performed before running any type of verification:
-
-```
-$ ./reactics setup
-```
-
-After performing these steps you should be ready to start using ReactICS.
-
-## Examples
-
-The `examples` directory contains sample input files.
-
-### Multi-agent reaction systems (rsCTLK verification)
-
-To quickly test the BDD module you can perform verification of the TGC controller consiting of three trains:
-
-```
-$ ./reactics bdd -c f1 examples/bdd/tgc.rs
-```
-
-The above command tests the formula labelled `f1` in the input file.
-
-### Reachability
-
-To test the SMT module you can perform reachability verification of the scalable chain system:
-
-Running the benchmark without any arguments tells us what parameters are available:
-
-```
-$ ./reactics smt examples/smt/scalable_chain.py
-
- ------------------------------------------------
- -- ReactICS -- Reaction Systems Model Checker --
- ------------------------------------------------
-
-arguments: <chainLen> <maxConc> <formulaNumber>
-```
-
-We may execute the benchmark for `chainLen=2`, `maxConc=3`, and `formulaNumber=1` using the following command:
-
-```
-$ ./reactics smt examples/smt/chain_reaction.py 2 3 1
-```
-
-### rsLTL verification
-
-To test the SMT module for rsLTL verification the scalable chain system benchmark may be used.
-
-
-
-```
-$ ./reactics smt examples/smt/scalable_chain.py 2 5 1
-```
-
-
-
-### Reaction synthesis
-
-To test the reaction synthesis approach on a mutual exclution protocol modelling three processes, run the following command (three processes, parametric verification, result optimised with OptSMT):
-
-```
-$ ./reactics smt examples/smt/mutex_param.py 3 p -o
-```
-
-To check the available parameters for the benchmark, we run it with `-h`:
-
-```
-$ ./reactics smt examples/smt/mutex_param.py -h
-
- ------------------------------------------------
- -- ReactICS -- Reaction Systems Model Checker --
- ------------------------------------------------
-
-usage: mutex_param.py [-h] [-v] [-o] scaling {p,np-p,np-np}
-
-positional arguments:
-  scaling         scaling parameter value
-  {p,np-p,np-np}  Selects the mode: p - parameter synthesis (parametric
-                  implementation), np-p - non-parametric with parametric
-                  implementation (with the parameters substituted), np-np -
-                  non-parametric with non-parametric implementation
-                  (parameters substituted)
-
-optional arguments:
-  -h, --help      show this help message and exit
-  -v, --verbose   turn verbosity on
-  -o, --optimise  minimise the parametric computation result
-```

+# Testing ReactICS
+
+## Prerequisites
+
+- **BDD module**: compiled (`./reactics setup` or `make` in `reactics-bdd/`)
+- **SMT module**: Python 3 with `z3-solver` and `pytest` installed
+
+```
+pip install z3-solver pytest
+```
+
+## Running all tests
+
+```
+./run_tests.sh
+```
+
+This runs the BDD, SMT, and generator test suites in sequence.
+
+## BDD tests
+
+```
+bash tests/run_tests.sh
+```
+
+10 regression tests that run the compiled `reactics-bdd/reactics` binary
+against example `.drs` files and compare output to saved baselines in
+`tests/expected/`. Covers:
+
+- Parsed system printing (`-P`)
+- Reaction listing (`-r`)
+- Reachable state enumeration (`-s`)
+- RSCTLK model checking (`-c`) for properties f1--f4
+
+Input files: `examples/bdd/tgc.drs`, `examples/bdd/tgc4.drs`,
+`reactics-bdd/in/trivial.drs`.
+
+To update baselines after an intentional output change, delete the
+relevant file in `tests/expected/` and re-run; the test will regenerate it.
+
+## SMT tests
+
+```
+python3 -m pytest tests/test_smt.py -v
+```
+
+23 pytest tests exercising the Python API directly. Organised by layer:
+
+- **Data model** -- ReactionSystem, concentrations, context automata,
+  formula construction (BagDescription, rsLTL)
+- **SmtCheckerRS** -- basic reachability (no concentrations)
+- **SmtCheckerRSC** -- reachability and rsLTL model checking with
+  concentrations (chain reaction, heat shock response)
+- **SmtCheckerRSCParam** -- parametric verification
+- **RSC-to-RS translation** -- verifying the translated system
+
+## Generator tests
+
+7 tests that run each generator (from `examples/bdd/generators/`),
+feed the output into the BDD model checker, and verify the expected
+verification result (holds / does not hold).
+
+Generators using old syntax (`examples/bdd/generators/old_syntax/`)
+are not tested this way as they are not compatible with the current
+parser.

+    <b>Reaction Systems</b> are a formalism inspired by the functioning of living cells.
+    They allow for specifying and analysing computational processes in which reactions operate on sets of molecules.
+</p>
+
+<p align="justify">
+    The behaviour of a reaction system is determined by the interactions of its reactions, which are based on
+    the mechanisms of facilitation and inhibition.
+    The formal treatment of reaction systems is qualitative and there is no direct representation of the number
+    of molecules involved in reactions.
+</p>
+
+<p align="justify">
+    A <b>Distributed Reaction System</b> is a computational model in which multiple autonomous processes (aka. agents)
+    interact locally through rule-based reactions.
+    Each agent operates independently (without any central controller—coordination),
+    processing inputs and producing outputs based on predefined reactions,
+    and their collective behavior leads to complex system dynamics.

+
+<h3>States</h3>
+
+<p align="justify">
+    A new state is created by left-clicking the edit area (the main part of the component).
+    As it is customary in automata theory, states are numbered separately starting from 1.
+    The types of states are distinguished by shape and colour:
+    the initial state is depicted as a square, all other states are depicted as circles.
+    Moreover, hovering the mouse above a state allows to see its full description containing both
+    its name and its (distinct) number.
+</p>
+<br/>
+<center><img src="img/ctx-automaton-state.png"/></center>
+
+<p align="justify">
+    The details of a state can be edited by right-clicking the existing
+    state and choosing the right option from the popup menu:
+    <ul>
+    <li><b>Set as initial</b> - Makes the selected state the initial state of the context automaton.</li>
+    <li><b>Set label</b> - Allows to set the custom label for the selected state. Note that state labels have to be unique.</li>
+    </ul>
+</p>
+<br/>
+<center><img src="img/ctx-automaton-state.png"/></center>
+
+<h3>Edges</h3>
+
+<p align="justify">
+    A directed edge between two states is created by left-clicking both its endpoints in correct order.
+    Each edge may contain several transitions, each of them defined by a <i>context</i> (additional entities
+    provided for active processes/agents) and a <i>guard</i> (a condition required by the transition to execute).
+    The list of transitions may be edited by right-clicking the existing
+    edge and choosing the <b>Nondeterministic transitions</b> popup menu.
+</p>
+<center><img src="img/ctx-automaton-transition-edit.png"/></center>

+    including context and guards.

+<center><img src="img/ctx-automaton-edge-details.png"/></center>
+
+<br/>
+
+<h3>Removing context automaton elements</h3>
+
+<p align="justify">
+    Switching the toggle button <b>Delete</b> on allows removing context automaton elements.
+    Each left-clicked element is removed from the automaton grapn.
+    Moreover, the entire context automaton graph may be deleted by clicking the <b>Clear</b> button.
+</p>
+
+<br/>
+
+<h3>Transforming the context automaton graph</h3>
+
+<p align="justify">
+    Any state of the automaton may be picked and dragged around the edit area to obtain the desired graph shape.
+    It is also possible to select multiple states and move them together at the same time.
+    After <b>CTRL + left-click</b> on a particular state the entire automaton graph is shifted to be centered
+    on the clicked state.
+    Checking the <b>Lock relative nodes positions</b> checkbox locks the relative positions of the states.
+    In that case, dragging a single state moves the entire automaton graph.
+    Moreover, using mouse scroll the automaton graph view can be zoomed in and out.

+
+<p align="justify">
+    The component offers the visualisation of the transition system representing the state space of the reaction systems.
+    The initial state is depicted as a square, all other states are depicted as circles.
+    There is a directed edge connecting the state S<sub>i</sub> to the state S<sub>j</sub>
+    if S<sub>f</sub> is reachable from S<sub>i</sub> by a single computation step of the reaction system.
+</p>
+
+<p align="justify">
+    The component has two separate instances represented by two separate tabs in the application window.
+    The first visualises the complete state space of the reaction system,
+    where each state is represented by sets of entities possessed by each agent and the current context automaton state.
+    The second visualises the compressed state space, where context automaton states are ignored
+    (states are represented only by the sets of entities possessed by each agent).
