+# exoscale-instance-type
+
+A parameter with all Exoscale instance types. This allows developers to select
+their desired virtuell machine for the workspace.
+
+Customize the preselected parameter value:
+
+```hcl
+module "exoscale-instance-type" {
+    source = "https://registry.coder.com/modules/exoscale-instance-type"
+    default = "standard.medium"
+}
+
+resource "exoscale_compute_instance" "instance" {
+  type        = module.exoscale-instance-type.value
+  ...
+}
+
+resource "coder_metadata" "workspace_info" {
+  item {
+    key   = "instance type"
+    value = module.exoscale-instance-type.name
+  }
+}
+```
+
+![Exoscale instance types](../.images/exoscale-instance-types.png)
+
+## Examples
+
+### Customize type
+
+Change the display name a type using the corresponding maps:
+
+```hcl
+module "exoscale-instance-type" {
+    source = "https://registry.coder.com/modules/exoscale-instance-type"
+    default = "standard.medium"
+    custom_names = {
+        "standard.medium": "Mittlere Instanz" # German translation
+    }
+    custom_descriptions = {
+        "standard.medium": "4 GB Arbeitsspeicher, 2 Kerne, 10 - 400 GB Festplatte" # German translation
+    }
+}
+
+resource "exoscale_compute_instance" "instance" {
+  type        = module.exoscale-instance-type.value
+  ...
+}
+
+resource "coder_metadata" "workspace_info" {
+  item {
+    key   = "instance type"
+    value = module.exoscale-instance-type.name
+  }
+}
+```
+
+![Exoscale instance types Custom](../.images/exoscale-instance-custom.png)
+
+### Use category and exlude type
+
+Show only gpu1 types
+
+```hcl
+module "exoscale-instance-type" {
+    source        = "https://registry.coder.com/modules/exoscale-instance-type"
+    default       = "gpu.large"
+    type_category = ["gpu"]
+    exclude       = [

+        "gpu3.medium",
+        "gpu3.large",
+        "gpu3.huge"
+    ]
+}
+
+resource "exoscale_compute_instance" "instance" {
+  type        = module.exoscale-instance-type.value
+  ...
+}
+
+resource "coder_metadata" "workspace_info" {
+  item {
+    key   = "instance type"
