+### Supported Polynomial Commitment Schemes
+
+The library supports six polynomial commitment schemes.
+
+#### Inner-product-argument PC
+
+A polynomial commitment scheme based on the hardness of the discrete logarithm problem in prime-order groups. 
+The construction is described in the following paper.

+
+#### Marlin variant of the Kate-Zaverucha-Goldberg PC
+
+Polynomial commitment based on the Kate-Zaverucha-Goldberg construction, with degree enforcement, batching, and (optional) hiding property taken from Marlin.
+The construction is described in the following papers.

+
+#### Sonic/AuroraLight variant of the Kate-Zaverucha-Goldberg PC
+
+Polynomial commitment based on the Kate-Zaverucha-Goldberg construction, with degree enforcement and batching taken from Sonic (more precisely, their counterparts in AuroraLight that avoid negative G1 powers). The (optional) hiding property of the commitment scheme follows the approach described in Marlin.
+The construction is described in the following papers.

+
+Multilinear polynomial commitment, introduced with Hyrax zkSNARK. Relies on Pedersen commitments and discrete logarithm problem for a hiding scheme. Construction details in the following paper.

+
+#### Marlin variant of the Papamanthou-Shi-Tamassia multivariate PC
+
+Multivariate polynomial commitment based on the construction in the Papamanthou-Shi-Tamassia construction with batching and (optional) hiding property inspired by the univariate scheme in Marlin.
+The construction is described in the following paper.

+
+### Comparison (WIP)
+
+#### Comparison of `MarlinKZG10` and `SonicKZG10`
+
+
+- High-level:
+They handle degree bounds differently. 
+MarlinPC uses shift powers only in G1 and requires two commitments to enforce degree bounds.
+SonicPC uses shift powers in G1 and G2 and requires only one commitment to enforce degree bounds.
+
+- Setup:
+SonicPC additionally computes some G2 elements for shift powers: `(1/\beta)^i H`. This results in a longer verifying key, as shift powers in SonicPC are in G2, while shift powers in Marlin are in G1, and are shared with the "non-shift" powers.
+
+- Commit:
+When there is no degree bound, both are the same.
+When there is a degree bound, MarlinPC is more expensive: it needs an additional commitment to commit to the shifted poynomial. 
+
+- Open: 
+When there is no degree bound, both are the same.
+When there is a degree bound, MarlinPC is slightly more expensive: it requires more scalar field computations.
+
+- Check:
+MarlinPC simply adjusts the commitment of the shifted polynomial, so the overhead is small. It checks a pairing equation with two pairing operations.
+SonicPC is more expensive, as it checks a pairing equation of three pairing operations. It can be reduced into two if there is no degree bound.
