+### Dash (DIPs)
+{% include helpers/subhead-links.md %}
+
+Similar to Bitcoin's BIPs, a Dash Improvement Proposal ([DIP](https://github.com/dashpay/dips)) is a design
+document for providing information to the Dash community, or describing a new
+feature for Dash processes/environment. The DIP should provide a
+concise technical specification of the feature and a rationale for the feature.

+### Bitcoin (BIPs)
+{% include helpers/subhead-links.md %}
+
+A Bitcoin Improvement Proposal (BIP) is a design document providing information
+to the Bitcoin community, or describing a new feature for Bitcoin or its
+processes or environment.
+
+Since Dash is forked from Bitcoin, some BIPs are applicable to both. The following
+table provides a list of the BIPs that are relevant to Dash. Some BIPs may only
+be partially implemented or modified to meet Dash requirements. The `Dash Status`
+column indicates if any changes were made.

+
+#### BIP Summary Table
+<!-- no subhead-links here -->
+
+Dash-specific BIP information derived from Dash developer
+[QuantumExplorer's BIP repository](https://github.com/QuantumExplorer/bips/blob/master/README.mediawiki).

+\* These BIPs are not Bitcoin or Dash specific (i.e. BIP-0044 Multi-Account Hierarchy for Deterministic Wallets). Generally relates to the Application Layer and not specifically the reference client.
