 `TopoModelX` (TMX) is a Python module for topological deep learning. It offers simple and efficient tools to implement topological neural networks for science and engineering.
 
-TMX's development follows the topological deep learning (TDL) blue print laid out in:
-- [Hajij et al. 2023. Topological Deep Learning: Going Beyond Graph Data](https://arxiv.org/abs/2206.00606).
+_**Note:** TMX is still under development._
+
+## Quick Tour for New Users
 
-TMX can reproduce and extend the topological neural networks (TNNs) surveyed in:
-- [Papillon et al. 2023. Architectures of Topological Deep Learning: A Survey on Topological Neural Networks](https://arxiv.org/abs/2304.10031).
+In this quick tour, we highlight the ease of creating and training a TNN model with only a few lines of code.
 
-See [our graphical literature review](https://github.com/pyt-team/TopoModelX/blob/main/topomodelx.jpeg) with message-passing equations available at [https://github.com/awesome-tnns/awesome-tnns](https://github.com/awesome-tnns/awesome-tnns).
+#Train your own TNN model
+
+Below is a minimal example of using TopoModelX to load a simplicial complex dataset, define a simplicial attention network (SAN), and perform a forward pass:
+
+
+```bash
+import numpy as np
+import toponetx as tnx
+import torch
+from topomodelx.nn.simplicial.san import SAN
+from topomodelx.utils.sparse import from_sparse
+
+# Step 1: Load the Karate Club dataset
+dataset = tnx.karate_club(complex_type="simplicial")
+
+# Step 2: Prepare Laplacians and node/edge features
+laplacian_down = from_sparse(dataset.down_laplacian_matrix(rank=1))
+laplacian_up = from_sparse(dataset.up_laplacian_matrix(rank=1))
+incidence_0_1 = from_sparse(dataset.incidence_matrix(rank=1))
+
+x_0 = torch.tensor(np.stack(list(dataset.get_simplex_attributes("node_feat").values())))
+x_1 = torch.tensor(np.stack(list(dataset.get_simplex_attributes("edge_feat").values())))
+x = x_1 + torch.sparse.mm(incidence_0_1.T, x_0)
+
+# Step 3: Define the network
+class Network(torch.nn.Module):
+    def __init__(self, in_channels, hidden_channels, out_channels):
+        super().__init__()
+        self.base_model = SAN(in_channels, hidden_channels, n_layers=2)
+        self.linear = torch.nn.Linear(hidden_channels, out_channels)
+
+    def forward(self, x, laplacian_up, laplacian_down):
+        x = self.base_model(x, laplacian_up, laplacian_down)
+        return torch.sigmoid(self.linear(x))
+
+# Step 4: Initialize the network and perform a forward pass
+model = Network(in_channels=x.shape[-1], hidden_channels=16, out_channels=2)
+y_hat_edge = model(x, laplacian_up=laplacian_up, laplacian_down=laplacian_down)
+   ```
+
+## 🤖 Installing TopoModelX
+
+`TopoModelX` is available on PyPI and can be installed using `pip`.
+Run the following command:
+
+```bash
+pip install topomodelx
+```
+
+Then install torch, torch-scatter, torch-sparse with or without CUDA depending on your needs.
+```bash
+pip install torch==2.0.1 --extra-index-url https://download.pytorch.org/whl/${CUDA}
+pip install torch-scatter torch-sparse -f https://data.pyg.org/whl/torch-2.0.1+${CUDA}.html
+pip install torch-cluster -f https://data.pyg.org/whl/torch-2.0.0+${CUDA}.html
+```
+where `${CUDA}` should be replaced by either `cpu`, `cu102`, `cu113`, or `cu115` depending on your PyTorch installation (`torch.version.cuda`).
