+
+### 2. License Grants and Conditions
+
+#### 2.1. Grants
+
+Each Contributor hereby grants You a world-wide, royalty-free, non-exclusive license:
+
+* **(a)** under intellectual property rights (other than patent or trademark)
+  Licensable by such Contributor to use, reproduce, make available, modify, display, perform, distribute, and otherwise

+the Contributor first distributes such Contribution.
+
+#### 2.3. Limitations on Grant Scope
+
+The licenses granted in this Section 2 are the only rights granted under this License. No additional rights or licenses
+will be implied from the distribution or licensing of Covered Software under this License. Notwithstanding Section 2.1(
+b) above, no patent license is granted by a Contributor:
+
+* **(a)** for any code that a Contributor has removed from Covered Software; or
+* **(b)** for infringements caused by: **(i)** Your and any other third party's modifications of Covered Software,
+  or **(ii)** the combination of its Contributions with other software (except as part of its Contributor Version); or
+* **(c)** under Patent Claims infringed by Covered Software in the absence of its Contributions.
+
+This License does not grant any rights in the trademarks, service marks, or logos of any Contributor (except as may be
+necessary to comply with the notice requirements in Section 3.4).
+
+#### 2.4. Subsequent Licenses
+
+No Contributor makes additional grants as a result of Your choice to distribute the Covered Software under a subsequent
+version of this License (see Section 10.2) or under the terms of a Secondary License (if permitted under the terms of
+Section 3.3).
+
+#### 2.5. Representation
+
+Each Contributor represents that the Contributor believes its Contributions are its original creation(s) or it has
+sufficient rights to grant the rights to its Contributions conveyed by this License.
+
+#### 2.6. Fair Use
+
+This License is not intended to limit any rights You have under applicable copyright doctrines of fair use, fair
+dealing, or other equivalents.
+
+#### 2.7. Conditions
+
+Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in Section 2.1.
+
+### 3. Responsibilities
+
+#### 3.1. Distribution of Source Form
+
+All distribution of Covered Software in Source Code Form, including any Modifications that You create or to which You
+contribute, must be under the terms of this License. You must inform recipients that the Source Code Form of the Covered
+Software is governed by the terms of this License, and how they can obtain a copy of this License. You may not attempt
+to alter or restrict the recipients' rights in the Source Code Form.
+
+#### 3.2. Distribution of Executable Form
+
+If You distribute Covered Software in Executable Form then:
+
+* **(a)** such Covered Software must also be made available in Source Code Form, as described in Section 3.1, and You
+  must inform recipients of the Executable Form how they can obtain a copy of such Source Code Form by reasonable means
+  in a timely manner, at a charge no more than the cost of distribution to the recipient; and
+
+* **(b)** You may distribute such Executable Form under the terms of this License, or sublicense it under different
+  terms, provided that the license for the Executable Form does not attempt to limit or alter the recipients' rights in
+  the Source Code Form under this License.
+
+#### 3.3. Distribution of a Larger Work
+
+You may create and distribute a Larger Work under terms of Your choice, provided that You also comply with the
+requirements of this License for the Covered Software. If the Larger Work is a combination of Covered Software with a
+work governed by one or more Secondary Licenses, and the Covered Software is not Incompatible With Secondary Licenses,
+this License permits You to additionally distribute such Covered Software under the terms of such Secondary License(s),
+so that the recipient of the Larger Work may, at their option, further distribute the Covered Software under the terms
+of either this License or such Secondary License(s).
+
+#### 3.4. Notices
+
+You may not remove or alter the substance of any license notices
+(including copyright notices, patent notices, disclaimers of warranty, or limitations of liability) contained within the
+Source Code Form of the Covered Software, except that You may alter any license notices to the extent required to remedy
+known factual inaccuracies.
+
+#### 3.5. Application of Additional Terms
+
+You may choose to offer, and to charge a fee for, warranty, support, indemnity or liability obligations to one or more
+recipients of Covered Software. However, You may do so only on Your own behalf, and not on behalf of any Contributor.
+You must make it absolutely clear that any such warranty, support, indemnity, or liability obligation is offered by You
+alone, and You hereby agree to indemnify every Contributor for any liability incurred by such Contributor as a result of
+warranty, support, indemnity or liability terms You offer. You may include additional disclaimers of warranty and
+limitations of liability specific to any jurisdiction.
+
+### 4. Inability to Comply Due to Statute or Regulation
+
+If it is impossible for You to comply with any of the terms of this License with respect to some or all of the Covered
+Software due to statute, judicial order, or regulation then You must: **(a)** comply with the terms of this License to
+the maximum extent possible; and **(b)**
+describe the limitations and the code they affect. Such description must be placed in a text file included with all
+distributions of the Covered Software under this License. Except to the extent prohibited by statute or regulation, such
+description must be sufficiently detailed for a recipient of ordinary skill to be able to understand it.
+
+### 5. Termination
+
+**5.1.** The rights granted under this License will terminate automatically if You fail to comply with any of its terms.
+However, if You become compliant, then the rights granted under this License from a particular Contributor are
+reinstated **(a)** provisionally, unless and until such Contributor explicitly and finally terminates Your grants,
+and **(b)** on an ongoing basis, if such Contributor fails to notify You of the non-compliance by some reasonable means
+prior to 60 days after You have come back into compliance. Moreover, Your grants from a particular Contributor are
+reinstated on an ongoing basis if such Contributor notifies You of the non-compliance by some reasonable means, this is
+the first time You have received notice of non-compliance with this License from such Contributor, and You become
+compliant prior to 30 days after Your receipt of the notice.
+
+**5.2.** If You initiate litigation against any entity by asserting a patent infringement claim (excluding declaratory
+judgment actions, counter-claims, and cross-claims) alleging that a Contributor Version directly or indirectly infringes
+any patent, then the rights granted to You by any and all Contributors for the Covered Software under Section 2.1 of
+this License shall terminate.
+
+**5.3.** In the event of termination under Sections 5.1 or 5.2 above, all end user license agreements (excluding
+distributors and resellers) which have been validly granted by You or Your distributors under this License prior to
+termination shall survive termination.
+
+### 6. Disclaimer of Warranty
+
+> Covered Software is provided under this License on an “as is”
+> basis, without warranty of any kind, either expressed, implied, or
+> statutory, including, without limitation, warranties that the
+> Covered Software is free of defects, merchantable, fit for a
+> particular purpose or non-infringing. The entire risk as to the
+> quality and performance of the Covered Software is with You.
+> Should any Covered Software prove defective in any respect, You
+> (not any Contributor) assume the cost of any necessary servicing,
+> repair, or correction. This disclaimer of warranty constitutes an
+> essential part of this License. No use of any Covered Software is
+> authorized under this License except under this disclaimer.
+
+### 7. Limitation of Liability
+
+> Under no circumstances and under no legal theory, whether tort
+> (including negligence), contract, or otherwise, shall any
+> Contributor, or anyone who distributes Covered Software as
+> permitted above, be liable to You for any direct, indirect,
+> special, incidental, or consequential damages of any character
+> including, without limitation, damages for lost profits, loss of
+> goodwill, work stoppage, computer failure or malfunction, or any
+> and all other commercial damages or losses, even if such party
+> shall have been informed of the possibility of such damages. This
+> limitation of liability shall not apply to liability for death or
+> personal injury resulting from such party's negligence to the
+> extent applicable law prohibits such limitation. Some
+> jurisdictions do not allow the exclusion or limitation of
+> incidental or consequential damages, so this exclusion and
+> limitation may not apply to You.
+
+### 8. Litigation
+
+Any litigation relating to this License may be brought only in the courts of a jurisdiction where the defendant
+maintains its principal place of business and such litigation shall be governed by laws of that jurisdiction, without
+reference to its conflict-of-law provisions. Nothing in this Section shall prevent a party's ability to bring
+cross-claims or counter-claims.
+
+### 9. Miscellaneous
+
+This License represents the complete agreement concerning the subject matter hereof. If any provision of this License is
+held to be unenforceable, such provision shall be reformed only to the extent necessary to make it enforceable. Any law
+or regulation which provides that the language of a contract shall be construed against the drafter shall not be used to
+construe this License against a Contributor.
+
+### 10. Versions of the License
+
+#### 10.1. New Versions
+
+Mozilla Foundation is the license steward. Except as provided in Section 10.3, no one other than the license steward has
+the right to modify or publish new versions of this License. Each version will be given a distinguishing version number.
+
+#### 10.2. Effect of New Versions
+
+You may distribute the Covered Software under the terms of the version of the License under which You originally
+received the Covered Software, or under the terms of any subsequent version published by the license steward.
+
+#### 10.3. Modified Versions
+
+If you create software not governed by this License, and you want to create a new license for such software, you may
+create and use a modified version of this License if you rename the license and remove any references to the name of the
+license steward (except to note that such modified license differs from this License).
+
+#### 10.4. Distributing Source Code Form that is Incompatible With Secondary Licenses
+
+If You choose to distribute Source Code Form that is Incompatible With Secondary Licenses under the terms of this
+version of the License, the notice described in Exhibit B of this License must be attached.

+# Kotlin Bitflags
+
+Kotlin-Bitflags is a utility library to simplify implementing bitflags in Kotlin. It integrates with Kotlin unsigned 
+types and Java Enumsets. This especially useful when interacting with binary protocols from Kotlin.
+
+## Using Kotlin-Bitflags
+
+After adding this module to your dependencies, you'll have to implement the related interfaces in your classes:
+
+```kotlin
+enum class MessageFlag(
+  override val value: UInt,
+) : Flag<UInt> {
+  Self(0x01u),
+  Highlight(0x02u),
+  Redirected(0x04u),
+  ServerMsg(0x08u),
+  Backlog(0x80u);
+
+  companion object : Flags<UInt, MessageFlag> {
+    override val all: Set<MessageFlag> = values().toEnumSet()
+  }
+}
+```
+
+This allows you to then use this elsewhere to e.g initialize a field from discrete values
+```kotlin
+// Construct from varargs or an array
+val field = MessageFlag.of(MessageFlag.Self, MessageFlag.Highlight)
+
+val values = listOf(MessageFlag.Self, MessageFlag.Highlight)
+// Or from a collection
+val field = MessageFlag.of(values)
+// Or use the to helper
+val field = values.toEnumSet()
+```
+
+You can also convert such a field into the raw binary value easily
+```kotlin
+// Returns in this case UInt
+field.toBits()
+```
+
+Additional utility functions are available:
+```kotlin
+// Empty field
+MessageFlag.none()
+// Get all non-null values
+MessageFlag.validValues()
+```
