+## Installation
+
+`conda-store` has two packages a `conda-store` (the client) and
+`conda-store-server` (the server). Make sure that either `conda` or
+`mamba` are in your path.
+
+```shell
+conda install -c conda-forge conda-store-server conda-store
+```
+
+The `conda-store` server can be easily launched in standalone mode
+that carries no dependencies on databases, object storage, redis.
+
+```
+conda-store-server --standalone
+```
+
+Standalone mode runs all components together to simplify
+deployment. For more complex and scalable setups there are
+[installation examples for containerized and distributed
+environments](docs/installation.md).
