 # okta-admin
-A minimal CLI to perform administrative tasks in Okta
+This is a Commandline application to perform administrative tasks in [Okta](https://www.okta.com).
+
+It does not allow you to make requests to arbitrary endpoints of the Okta API. Rather, it is designed to speed up frequently performed administrative tasks like creating users, adding them to groups, listing resources and so forth.
+
+## Usage
+Download the pre-compiled binary for your platform from the [Releases](https://github.com/duaraghav8/okta-admin/releases) page or compile the code for your platform using `make build`.
+
+Use `-help` to display the list of commands available and to get information about specific commands.
+
+### Examples
+1. Create a new user in your Okta Organization
+```bash
+okta-admin create-user \
+    -org-url https://hogwarts.okta.co.uk \
+    -api-token xxxxx \
+    -email [email protected] \
+    -fname Harry -lname Potter \
+    -team Seekers
+```
+The above command creates a new user in an organization and assigns them a Team. It also highlights how you can specify the organization URL and Okta API Token via commandline arguments, although **this is not the recommended way to supply credentials**.
+
+2. Add a member to groups in the organization
+```bash
+export OKTA_ORG_URL="https://hogwarts.okta.com/"
+export OKTA_API_TOKEN="xxxxx"
+
+okta-admin assign-groups -email [email protected] -groups TheOrder
+
+okta-admin assign-groups \
+    -email [email protected] \
+    -groups "Slytherin, pure-blood, rich_kids"
+
+okta-admin assign-groups \
+    -email [email protected] \
+    -groups hogwarts-alumni,MinistryOfMagic
+```
+These commands demonstrate the different ways in which you can specify `groups` to assign to a member. Any option capable of accepting multiple values can be given a comma-separated list of them. Notice how the organization credentials this time are passed via environment variables. This is the recommended way to work with Okta Admin, especially when running the tool in automation.
+
+3. List Groups present in the organization
+```bash
+source ~/.okta/creds.env
+
+# List names of all groups
+okta-admin list-groups
+
+# Get info about select groups
+okta-admin list-groups -groups azkaban,durmstrang -detailed
+```
+
+## Developing
+After cloning this repository, run `make bootstrap` to download tools necessary for developing. This project uses [Go Modules](https://blog.golang.org/using-go-modules) for dependency management.
+
+Use `make test` to run tests and `make fmt` to run `gofmt` over the codebase. Finally, run `make build` to build binaries for distribution.
