 ### Next, in-development
 
+- TBD
+
+### Version 2.2.0, October 28, 2025
+
 Our current priorities to support metrics for advanced database features and use cases, like Exadata, GoldenGate, and views included in the Oracle Diagnostics Pack.
 
+- Allow loading database credentials from [HashiCorp Vault](../configuration/hashicorp-vault.md).
 - Added experimental support for the [go-ora](https://github.com/sijms/go-ora)
 - Move `oracledb_dbtype` metric to the default metrics. You may now disable or override this metric like any other database metric.
 - Document required database permissions for the exporter.
 - Fix an issue where some metrics would not be cached when using a per-metric scrape interval with a global scrape interval.
+- Update third party dependencies
+- Update Go runtime to 1.24.9

+# Development
+
+The exporter is a Go program using the Prometheus SDK. 
+
+External contributions are welcome, see [CONTRIBUTING](https://github.com/oracle/oracle-db-appdev-monitoring/blob/main/CONTRIBUTING.md) for details.
+
+The exporter initialization is as follows:
+
+- Parse flags options and configuration properties
+- Load the default toml file (`default-metrics.toml`) and store each metric in a `Metric` struct
+- Load the custom toml file (if a custom toml file is given)
+- Create an `Exporter` object
+- Register exporter in prometheus library
+- Launching a web server to handle incoming requests
+- Attempt connection to any configured Oracle Database servers
+
+These operations are mainly done in the `main` function.
+
+After this initialization phase, the exporter will wait for the arrival of a request.
+
+Each time, it will iterate over the content of the `metricsToScrape` structure (in the function scrape `func (e * Export) scrape (ch chan <- prometheus.Metric)`).
+
+For each element (of `Metric` type), a call to the `ScrapeMetric` function will be made which will itself make a call to the `ScrapeGenericValues` function.
+
+The `ScrapeGenericValues` function will read the information from the `Metric` structure and, depending on the parameters, will generate the metrics to return. In particular, it will use the `GeneratePrometheusMetrics` function which will make SQL calls to the database.
+
+### Docker/container build
+
+To build a container image, run the following command:
+
+```bash
+make docker
+```
+
+For ARM:
+
+```bash
+make docker-arm
+```
+
+### Building Binaries
+
+Run build:
+
+```bash
+make go-build
+```
+
+This will create binaries and archives inside the `dist` folder for the building operating system.

+
+# Using the go-ora database driver
+
+The Oracle Database Metrics Exporter experimentally supports compiling with the [go-ora database driver](https://github.com/sijms/go-ora).  By default, the exporter compiles using the `godror` database driver, which uses CGO execution to invoke Oracle Instant Client. the go-ora driver presents an option for users who want to use a "thin" database client without the Oracle Instant Client and CGO.
+
+### Configuring go-ora
+
+Because go-ora does not use Oracle Instant Client, it is recommended to provide all connection string options in the `database.url` property:
+
+```yaml
+databases:
+  go_ora_db:
+    username: myuser
+    password: ******
+    url: my_tnsname?wallet=/path/to/wallet&ssl=1
+```
+
+### Build with go-ora
+
+To build using `go-ora` instead of `godror`, set `TAGS=goora CGO_ENABLED=0`:
+
+```bash
+make go-build TAGS=goora CGO_ENABLED=0
+```
