+
+## Overview
+
+An Aspire component leveraging the [Ollama](https://ollama.com) container with support for downloading a model on startup.
+
+## Usage
+
+Use the static `AddOllama` method to add this container component to the application builder.
+
+```csharp
+// The distributed application builder is created here
+
+var ollama = builder.AddOllama("ollama");
+
+// The builder is used to build and run the app somewhere down here
+```
+
+### Configuration
+
+The AddOllama method has optional arguments to set the `name`, `port` and `modelName`.
+The `name` is what gets displayed in the Aspire orchestration app against this component.
+The `port` is provided randomly by Aspire. If for whatever reason you need a fixed port, you can set that here.
+The `modelName` specifies what LLM to pull when it starts up. The default is `llama3`. You can also set this to null to prevent any models being pulled on startup - leaving you with a plain Ollama container to work with.
+
+## Downloading the LLM
+
+When the Ollama container for this component first spins up, this component will download the LLM (llama3 unless otherwise specified).
+The progress of this download will be displayed in the State column for this component on the Aspire orchestration app.
+Important: Keep the Aspire orchestration app open until the download is complete, otherwise the download will be cancelled.
+In the spirit of productivity, we recommend kicking off this process before heading for lunch.
+This component binds a volume called "ollama" so that once the model is fully downloaded, it'll be available for subsequent runs.
+
+## Accessing the Ollama server from other Aspire components
+
+You can pass the ollama component to other Aspire components in the usual way:
+
+```csharp
+builder.AddMyComponent().WithReference(ollama);
+```
+
+Within that component (e.g. a web app), you can fetch the Ollama connection string from the application builder as follows.
+Note that if you changed the name of the Ollama component via the `name` argument, then you'll need to use that here when specifying which connection string to get.
+
+```csharp
+var connectionString = builder.Configuration.GetConnectionString("Ollama");
+```
+
+You can then call any of the Ollama endpoints through this connection string. We recommend using the [OllamaSharp](https://www.nuget.org/packages/OllamaSharp) client to do this.
