+### Building from scratch
+To reduce compile times, we recommend using a pre-built version of `rocksdb`, either from the system package manager or e.g. via `conda`:
+
+```bash
+# Ubuntu
+sudo apt-get install librocksdb-dev
+
+# Conda
+conda install -c conda-forge rocksdb
+```
+
+In either case, either add
+```toml
+[env]
+ROCKSDB_LIB_DIR = "/usr/lib/" # in case of the system package manager, adjust the path accordingly for conda
+SNAPPY_LIB_DIR = "/usr/lib/"  # same as above
+```
+to `.cargo/config.toml` or set the environment variables `ROCKSDB_LIB_DIR` and `SNAPPY_LIB_DIR` to the appropriate paths:
+
+```bash
+export ROCKSDB_LIB_DIR=/usr/lib/
+export SNAPPY_LIB_DIR=/usr/lib/
+```
+
+By default, the environment variables are defined in the `.cargo/config.toml` as described above, i.e. may need adjustments if not using the system package manager.
+
+To build the project, run:
+```bash
+cargo build --release
+```
+
+To install the project locally, run:
+```bash
+cargo install --path .
