+
+Configuration limit
+===================
+
+Using a first-order Taylor expansion on the configuration, we can write the limit as:
+
+.. math::
+    \begin{aligned}
+    q_{\text{min}} &\leq q \oplus v \cdot dt \leq q_{\text{max}} \\
+    q_{\text{min}} &\leq q \oplus \Delta q \leq q_{\text{max}} \\
+    q_{\text{min}} &\ominus q \leq \Delta q \leq q_{\text{max}} \ominus q
+    \end{aligned}
+
+Rewriting as :math:`G \Delta q \leq h`, we separate the inequalities:
+
+.. math::
+    \begin{aligned}
+    &+I \cdot \Delta q \leq q_{\text{max}} \ominus q \\
+    &-I \cdot \Delta q \leq q \ominus q_{\text{min}}
+    \end{aligned}
+
+Stacking these inequalities, we define:
+
+.. math::
+    \begin{aligned}
+    G &= \begin{bmatrix} +I \\ -I \end{bmatrix}, \\
+    h &= \begin{bmatrix} q_{\text{max}} \ominus q \\ q \ominus q_{\text{min}} \end{bmatrix}
+    \end{aligned}
+
+Velocity limit
+==============
+
+Given the maximum joint velocity magnitudes :math:`v_{\text{max}}`, the joint velocity limits can be expressed as:
+
+.. math::
+    \begin{aligned}
+    -v_{\text{max}} &\leq v \leq v_{\text{max}} \\
+    -v_{\text{max}} &\leq \frac{\Delta q}{dt} \leq v_{\text{max}} \\
+    -v_{\text{max}} \cdot dt &\leq \Delta q \leq v_{\text{max}} \cdot dt
+    \end{aligned}
+
+Rewriting as :math:`G \Delta q \leq h`, we separate the inequalities:
+
+.. math::
+    \begin{aligned}
+    &+I \cdot \Delta q \leq v_{\text{max}} \cdot dt \\
+    &-I \cdot \Delta q \leq v_{\text{max}} \cdot dt
+    \end{aligned}
+
+Stacking these inequalities, we define:
+
+.. math::
+    \begin{aligned}
+    G \Delta q &\leq h \\
+    \begin{bmatrix} +I \\ -I \end{bmatrix} \Delta q &\leq \begin{bmatrix} v_{\text{max}} \cdot dt \\ v_{\text{max}} \cdot dt \end{bmatrix}
+    \end{aligned}

+Lie
+***
+
+MuJoCo does not currently offer a native Lie group interface for rigid body transforms, though it
+does have a collection of functions for manipulating quaternions and rotation matrices. The goal
+of this library is to provide this unified interface. Whenever possible, the underlying
+lie operation leverages the corresponding MuJoCo function. For example,
+:py:meth:`~SO3.from_matrix` uses `mujoco.mju_mat2Quat` under the hood.
+
+This library is heavily ported from `jaxlie <https://github.com/brentyi/jaxlie>`__,
+swapping out JAX for Numpy and adding a few additional features.
