 As per BIP1 _BIP Purpose and Guidelines_, there are three((("BIPs (Bitcoin Improvement Proposals)", "types of"))) kinds of BIPs:
 
 _Standard_ BIP:: Describes any change that affects most or all Bitcoin implementations, such as a change to the network protocol, a change in block or transaction validity rules, or any change or addition that affects the interoperability of applications using Bitcoin.
-_Informational_ BIP:: Describes a Bitcoin design issue or provides general guidelines or information to the Bitcoin community, but does not propose a new feature. Informational BIPs do not necessarily represent a Bitcoin community consensus or recommendation, so users and implementors may ignore informational BIPs or follow their advice.

Informational BIPs do not necessarily represent a Bitcoin community consensus or recommendation, so users and implementers may ignore informational BIPs or follow their advice.
 _Process_ BIP:: Describes a Bitcoin process or proposes a change to (or an event in) a process. Process BIPs are like standard BIPs but apply to areas other than the Bitcoin protocol itself. They might propose an implementation but not to Bitcoin's codebase; they often require community consensus. Unlike informational BIPs, they are more than recommendations, and users are typically not free to ignore them. Examples include procedures, guidelines, changes to the decision-making process, and changes to the tools or environment used in Bitcoin development. Any meta-BIP is also considered a process BIP.
 
 BIPs are recorded in a https://oreil.ly/jjO0R[versioned repository on GitHub].
