+# ns-train
+
+Primary interface for training a NeRF model. `--help` is your friend when navigating command arguments. We also recommend installing the tab completion `ns-install-cli`.
+
+```bash
+usage: ns-train {method} [method args] {dataparser} [dataparser args]
+```
+
+If you are using a nerfstudio data set, the minimal command is:
+
+```bash
+ns-train nerfacto --data YOUR_DATA
+```
+
+To learn about the available methods:
+
+```bash
+ns-train --help
+```
+
+To learn about a methods parameters:
+
+```bash
+ns-train {method} --help
+```
+
+By default the nerfstudio dataparser is used. If you would like to use a different dataparser it can be specified after all of the method arguments. For a list of dataparser options:
+
+```bash
+ns-train {method} {dataparser} --help
+```
