+
+To index [Dotnet](https://dotnet.microsoft.com/) we use SourceGraph's [SCIP indexer for dotnet](https://github.com/sourcegraph/scip-dotnet). [SCIP](https://about.sourcegraph.com/blog/announcing-scip) is a new format for tools to share information about code. Releases of [scip-dotnet](https://github.com/sourcegraph/scip-dotnet) can be installed with `dotnet tools` and used as indexers for SCIP, which Glean will accept. The indexer itself requires a [dotnet](https://dotnet.microsoft.com/) runtime environment.
+
+## Run the indexer
+
+The indexer is run via the main `glean` CLI tool.
+
+```
+> cabal build exe:glean
+```
+
+And index your Dotnet repository with:
+```
+glean index dotnet-scip DIR --db NAME/INSTANCE
+```
+
+where
+
+* `DIR` is the root directory containing the Dotnet project
+* `name/hash` is the name of the repository to create
+
+Provide the usual `--db-root` and `--schema` or `--service` arguments
+to `glean`
+
+## In the shell
+
+Dotnet source can also be indexed directly from the Glean shell:
+
+```
+:index dotnet-scip DIR
+```
+
+The shell will pick a DB name and hash for you based on `DIR`.
+
+## Schema
+
+The schema is in <SrcFile file="glean/schema/source/scip.angle" />
