Good enough for a alpha release?

+![GitHub Workflow Status](https://img.shields.io/github/workflow/status/neachdainn/rubullet/Rust)
+# RuBullet
+
+RuBullet is a Rust implementation of [PyBullet](https://pybullet.org/).
+In other words, it uses the [Bullet3](https://github.com/bulletphysics/bullet3) 
+C API in order to expose a functionality that is similar to PyBullet.
+Development is ongoing and functionality is currently limited.
+
+## Status
+Right now RuBullet should cover most of the basic use cases. It can:
+* Create a PhysicsClient in either Direct or Gui mode
+* Load models from URDF, SDF or MuJoCo files
+* Create own models within the simulation
+* Control robots in position, velocity or torque mode
+* Calculate inverse dynamics, inverse kinematics, jacobians and mass matrices
+* Render camera images
+* Read information about links and joints
+* Change linear and angular damping of joints
+* Create GUI sliders, button or put debugging text or lines in the simulation
+* Get keyboard and mouse events 
+
+Things which are not implemented yet:
+* Collision Detection Queries 
+* Virtual Reality
+* Connect via SHARED_MEMORY, UDP or TCP
+* Plugins
+* Deformables and Cloth
+* Logging and saving states
+* Creating constraints
+* Set physics engine parameters
+* Change other dynamics parameters apart from linear and angular damping
+
+The API is unstable and subject to change.
+
+# Example
+```rust
+use std::{thread, time::Duration};
+
+use anyhow::Result;
+use nalgebra::{Isometry3, Vector3};
+use rubullet::*;
+
+fn main() -> Result<()> {
+    let mut physics_client = PhysicsClient::connect(Mode::Gui)?;
+
+    physics_client.set_additional_search_path("../rubullet-sys/bullet3/libbullet3/data")?;
+    physics_client.set_gravity(Vector3::new(0.0, 0.0, -10.0))?;
+
+    let _plane_id = physics_client.load_urdf("plane.urdf", Default::default())?;
+
+    let cube_start_position = Isometry3::translation(0.0, 0.0, 1.0);
+    let box_id = physics_client.load_urdf(
+        "r2d2.urdf",
+        UrdfOptions {
+            base_transform: cube_start_position,
+            ..Default::default()
+        },
+    )?;
+
+    for _ in 0..10000 {
+        physics_client.step_simulation()?;
+        thread::sleep(Duration::from_micros(4167));
+    }
+
+    let cube_transform = physics_client.get_base_transform(box_id)?;
+    println!("{}", cube_transform);
+
+    Ok(())
+}
+```

+## Bug reports and Merge Requests
+The current development happens as a part of marcbone's master thesis. Therefore, merge requests can not be accepted until
+July 5, 2021. We are disabling merge requests until then which sadly also disables issues. If you find any bugs or have suggestions please write an email to
+one of the maintainers.
