+
+## Theoretical Foundations
+
+### Core Interface
+
+The `IDAOCore` interface ties all the other components together and offers the main entry points for interacting with the DAO.
+
+**Interface Definition:**
+
+```go
+type IDAOCore interface {
+	Render(path string) string
+
+	VotingModule() IVotingModule
+	ProposalModules() []ActivableProposalModule
+	ActiveProposalModuleCount() int
+	Registry() *MessagesRegistry
+
+	UpdateVotingModule(newVotingModule IVotingModule)
+	UpdateProposalModules(toAdd []IProposalModule, toDisable []int)
+}
+```
+
+A default implementation is provided in the package `gno.land/p/demo/teritori/dao_core`, and custom implementations are generally not required.
+
+### A voting module
+
+### Voting Module
+
+The `gno.land/p/demo/teritori/dao_interfaces.IVotingModule` interface defines how voting power is allocated to addresses within the DAO.
+
+**Interface Definition:**
+
+```go
+type IVotingModule interface {
+	Info() ModuleInfo
+	ConfigJSON() string
+	Render(path string) string
+	VotingPowerAtHeight(address std.Address, height int64) (power uint64)
+	TotalPowerAtHeight(height int64) uint64
+}
+```
+
+There is only one implementation currently, `gno.land/p/demo/teritori/dao_voting_group`, it's a wrapper around a gno group, providing a membership-based voting power definition
+
+### Proposal Modules
+
+A proposal module (`gno.land/p/demo/teritori/dao_interfaces.IProposalModule`) is responsible for:
+- Receiving proposals, the proposal type is defined by the module
+- Managing the proposals lifecycle
+- Tallying votes, the vote type is defined by the module and the associated voting power is queried from the voting module
+- Executing proposals once they are passed
+
+**Interface Definition:**
+```go
+type IProposalModule interface {
+	Core() IDAOCore
+	Info() ModuleInfo
+	ConfigJSON() string
+	Render(path string) string
+	Execute(proposalID int)
+	VoteJSON(proposalID int, voteJSON string)
+	ProposeJSON(proposalJSON string) int
+	ProposalsJSON(limit int, startAfter string, reverse bool) string
+	ProposalJSON(proposalID int) string
+}
+```
+
+There is only one implementation currently, `gno.land/p/demo/teritori/dao_proposal_single`, providing a yes/no/abstain vote model with quorum and threshold
+
+### Message handlers
+
+Proposals actions are encoded as objects implementing `gno.land/p/demo/teritori/dao_interfaces.ExecutableMessage`
+```go
+type ExecutableMessage interface {
+	ujson.JSONAble
+	ujson.FromJSONAble
+
+	String() string
+	Type() string
+}
+```
+
+They are deserialized and executed by message handlers implementing `gno.land/p/demo/teritori/dao_interfaces.MessageHandler`
+```go
+type MessageHandler interface {
+	Execute(message ExecutableMessage)
+	MessageFromJSON(ast *ujson.JSONASTNode) ExecutableMessage
+	Type() string
+}
+```
+
+Message handlers are registered at core creation and new message handlers can be registered via proposals to extend the DAO capabilities
+
+## Practical Implementation
+
+### Setting Up Your Workspace
+
+Sooo, let's create a new realm
+
+```
+git clone https://github.com/TERITORI/gno.git gno-dao-tutorial
+cd gno-dao-tutorial
+git checkout teritori-unified
+mkdir examples/gno.land/r/demo/my_dao
+```
+
+### Creating the Voting Module
+
+We will start by instantiating a voting module
+
+1. **Initialize the Factory**
+
+Modules instantiation uses the factory pattern in case the module needs to access the core
+
+`examples/gno.land/r/demo/my_dao/my_dao.gno`
+```go
+package my_dao
+
+import (
+    "gno.land/p/demo/teritori/dao_interfaces"
+)
+
+func init() {
+    votingModuleFactory := func(core dao_interfaces.IDAOCore) {
+
+    }
+}
+```
+
+2. **Create the Group**
+
+First we need to create a group that will be queried by the module. We use the teritori fork of the groups realm since the upstream groups can't be created by a non-EOA
+
+`examples/gno.land/r/demo/my_dao/my_dao.gno`
+```go
+package my_dao
+
+import (
+    "gno.land/p/demo/teritori/dao_interfaces"
+    "gno.land/p/demo/teritori/groups" // <- new
+)
+
+func init() {
+    votingModuleFactory := func(core dao_interfaces.IDAOCore) {
+        group := groups.CreateGroup("my_dao_voting_group") // <- new
+    }
+}
+```
+
+3. **Add Initial Members**
+
+`examples/gno.land/r/demo/my_dao/my_dao.gno`
+```go
+func init() {
+    votingModuleFactory := func(core dao_interfaces.IDAOCore) {
+        group := groups.CreateGroup("my_dao_voting_group")
+        groups.AddMember(groupID, "your-address", 1, "") // <- new
+        // repeat for any other initial members you want in the DAO
+    }
+}
+```
+
+4. **Instantiate the voting module**
+
+`examples/gno.land/r/demo/my_dao/my_dao.gno`
+```go
+func init() {
+    package my_dao
+
+    import (
+        "gno.land/p/demo/teritori/dao_interfaces"
+        "gno.land/p/demo/teritori/groups"
+        "gno.land/p/demo/teritori/dao_voting_group" // <- new
+    )
+
+
+    votingModuleFactory := func(core dao_interfaces.IDAOCore) dao_interfaces.IVotingModule {
+        group := groups.CreateGroup("my_dao_voting_group")
+        groups.AddMember(groupID, "your-address", 1, "")
+        return dao_voting_group.NewVotingGroup(groupID) // <- new
+    }
+}
+```
+
+Now let's create a proposal module
+
+### Creating the proposal module
+
+1. **Initialize the Factory**
+
+`examples/gno.land/r/demo/my_dao/my_dao.gno`
+```go
+func init() {
+    votingModuleFactory := func(core dao_interfaces.IDAOCore) {
+        // ...
+    }
+    proposalModuleFactories := []dao_interfaces.ProposalModuleFactory{
+        func(core dao_interfaces.IDAOCore) dao_interfaces.IProposalModule {
+
+        },
+    }
+}
+```
+
+2. **Configure and instantiate the Proposal Module**
+
+`examples/gno.land/r/demo/my_dao/my_dao.gno`
+```go
+package my_dao
+
+import (
+    "gno.land/p/demo/teritori/dao_interfaces"
+    "gno.land/p/demo/teritori/groups"
+    "gno.land/p/demo/teritori/dao_voting_group"
+    "gno.land/p/demo/teritori/dao_proposal_single" // <- new
+)
+
+func init() {
+    // ...
+    proposalModuleFactories := []dao_interfaces.ProposalModuleFactory{
+        func(core dao_interfaces.IDAOCore) dao_interfaces.IProposalModule {
+            tt := dao_proposal_single.PercentageThresholdPercent(100) // 1% threshold
+			tq := dao_proposal_single.PercentageThresholdPercent(100) // 1% quorum
+			return dao_proposal_single.NewDAOProposalSingle(core, &dao_proposal_single.DAOProposalSingleOpts{
+				MaxVotingPeriod: time.Hour * 24 * 42,
+				Threshold: &dao_proposal_single.ThresholdThresholdQuorum{
+					Threshold: &tt,
+					Quorum:    &tq,
+				},
+			})
+        },
+    }
+}
+```
+
+### Registering Message Handlers
+
+Add message handlers to allow your DAO to perform specific actions when proposals are executed.
+
+`examples/gno.land/r/demo/my_dao/my_dao.gno`
+```go
+package my_dao
+
+import (
+    "gno.land/p/demo/teritori/dao_interfaces"
+    "gno.land/p/demo/teritori/groups"
+    "gno.land/p/demo/teritori/dao_voting_group"
+    "gno.land/p/demo/teritori/dao_proposal_single"
+)
+
+func init() {
+    // ...
+    messageHandlersFactories := []dao_interfaces.MessageHandlerFactory{
+        // Allow to manage the voting group
+        func(core dao_interfaces.IDAOCore) dao_interfaces.MessageHandler {
+            return groups.NewAddMemberHandler(groupID) // TODO: keep ref to groupID in previous parts
+        },
+        func(core dao_interfaces.IDAOCore) dao_interfaces.MessageHandler {
+            return groups.NewDeleteMemberHandler(groupID) // TODO: keep ref to groupID in previous parts
+        },
+        // Allow to update the proposal module settings
+        func(core dao_interfaces.IDAOCore) dao_interfaces.MessageHandler {
+            return dao_proposal_single.NewUpdateSettingsHandler(proposalModule) // TODO: keep ref to proposal module in previous parts
+        },
+    }
+}
+```
+
+### Creating the DAO Core
+
+Now we can create the actual DAO
+
+```go
+package my_dao
+
+import (
+    "gno.land/p/demo/teritori/dao_interfaces"
+    "gno.land/p/demo/teritori/groups"
+    "gno.land/p/demo/teritori/dao_voting_group"
+    "gno.land/p/demo/teritori/dao_proposal_single"
+    "gno.land/p/demo/teritori/dao_core" // <- new
+)
+
+var (
+    daoCore dao_interfaces.IDAOCore // <- new
+)
+
+func init() {
+    // ...
+    messageHandlersFactories := []dao_interfaces.MessageHandlerFactory{
+        // ...
+    }
+    daoCore = dao_core.NewDAOCore(votingModuleFactory, proposalModuleFactories, messageHandlersFactories) // <- new
+}
+```
+
+We also need to expose the DAO methods in the realm
+
+```go
+func init() {
+    // ...
+}
+
+func Render(path string) string {
+	return daoCore.Render(path)
+}
+
+func VoteJSON(moduleIndex int, proposalID int, voteJSON string) {
+	module := dao_core.GetProposalModule(daoCore, moduleIndex)
+	if !module.Enabled {
+		panic("proposal module is not enabled")
+	}
+	module.Module.VoteJSON(proposalID, voteJSON)
+}
+
+func Execute(moduleIndex int, proposalID int) {
+	module := dao_core.GetProposalModule(daoCore, moduleIndex)
+	if !module.Enabled {
+		panic("proposal module is not enabled")
+	}
+	module.Module.Execute(proposalID)
+}
+
+func ProposeJSON(moduleIndex int, proposalJSON string) int {
+	module := dao_core.GetProposalModule(daoCore, moduleIndex)
+	if !module.Enabled {
+		panic("proposal module is not enabled")
+	}
+	return module.Module.ProposeJSON(proposalJSON)
+}
+
+func getProposalsJSON(moduleIndex int, limit int, startAfter string, reverse bool) string {
+	module := dao_core.GetProposalModule(daoCore, moduleIndex)
+	return module.Module.ProposalsJSON(limit, startAfter, reverse)
+}
+
+func getProposalJSON(moduleIndex int, proposalIndex int) string {
+	module := dao_core.GetProposalModule(daoCore, moduleIndex)
+	return module.Module.ProposalJSON(proposalIndex)
+}
+```
+
+## Deploying and Interacting with Your DAO
+
+*TODO: Add instructions for deploying and interacting with the DAO.*
+
+---
+
+That's it! You've successfully created your first DAO using the Gno DAO framework. To expand its capabilities, you can register additional message handlers or update the existing modules.
