-This README must be written yet! :(
+## Table of Contents
 
+- Usage
+- Structure of the output file
+
+## Usage
+
+Typing `restG4 -h` will show all available options.
+
+### Basic Usage
+
+`restG4 simulation.rml` will launch a simulation using `simulation.rml` as the configuration file. The output file will
+be saved to the specified path in the configuration.
+
+### Multithreading
+
+`restG4` makes use of the multithreading capabilities of Geant4 and can be used in multithreading mode to significantly
+increase simulation speed.
+
+- `restG4 simulation.rml -t 8` will launch a simulation using 8 worker threads.
+
+By default `restG4` is executed in serial mode (one single thread) and is equivalent to the `-t 0` option.
+
+Simulation results are determined by the random seed and the number of threads, so using different number of threads
+with the same seed will produce different results. Using the same seed and same number of threads produces the same
+results.
+
+The multithreading implementation of `restG4` is new and although it looks to work properly it may have some bugs. If
+you find one of such bugs, please post an issue [here](https://github.com/rest-for-physics/restG4/issues) with
+the `multithreading` label.
+
+We encourage our users to use the multithreading feature especially when performing exploratory simulations.
+
+### Overriding values from the RML
+
+The CLI interface allows to set a few different parameters without having to modify the RML.
+
+- `restG4 simulation.rml -o output.root` to specify the output file.
+- `restG4 simulation.rml -n 1000` to set the number of processed events
+  (`n` in Geant4's `/run/beamOn n` or `nEvents` in the rml configuration).
+- `restG4 simulation.rml -g geometry.gdml` to specify the geometry file.
+
+### Ending the simulation early
+
+The simulation run will naturally end when the selected number of events have been processed. They can either be
+specified in the RML file or via the `-n` flag on the CLI. However, the user can also specify additional conditions to
+end the simulation early.
+
+- `restG4 simulation.rml -N 1000` will signal the simulation to stop once 1000 events have been marked as valid (saved
+  on the output file). The final simulation will probably have a slightly higher number of entries than the value
+  specified in the case of multithreading as the worker threads may still be working on valid events, or they may not
+  have been saved yet. The number of processed events (the equivalent of `nEvents`) will be adjusted to the real number
+  of processed events, overriding the selected value of the user, so the resulting simulation would be equivalent to a
+  plain simulation using this value as `nEvents`. This holds more accurately the large the `-N` parameter.
+- `restG4 simulation.rml -S 1h20m30s` will signal the simulation to stop after 1 hour 20 minutes and 30 seconds have
+  elapsed since the start. You can specify any value using this format such as `1h15m`, `30s`, etc.
+- Sending the interrupt signal (typically via `CTRL+C`) will signal the simulation to stop, and it will attempt to save
+  the results into disk before closing the process.
